Safety Precautions

Failure to comply with the precautions below could lead to injury or death or damage to the instrument.

WARNING

Use the Instrument Only for Its Intended Purpose

This instrument is a waveform measuring device that monitors and measures electrical signals. Do not use this instrument for anything other than as a waveform measuring device.

Check the Physical Appearance

Do not use the instrument if there is a problem with its physical appearance.

Use the Correct Power Supply

Before connecting the power cord, ensure that the source voltage matches the rated supply voltage of the instrument and that it is within the maximum rated voltage of the provided power cord.

Use the Correct Power Cord and Plug

To prevent the possibility of electric shock or fire, be sure to use the power cord supplied by YOKOGAWA. The main power plug must be plugged into an outlet with a protective earth terminal. Do not invalidate this protection by using an extension cord without protective earth grounding. Additionally, do not use the power cord supplied with this instrument with another instrument.

Connect the Protective Grounding Terminal

Make sure to connect the protective earth to prevent electric shock before turning ON the power. The power cord that comes with the instrument is a threeprong type power cord. Connect the power cord to a properly grounded threeprong outlet.

Do Not Impair the Protective Grounding

Never cut off the internal or external protective earth wire or disconnect the wiring of the protective earth terminal. Doing so poses a potential shock hazard.

Do Not Operate with Defective Protective Grounding or Fuse

Do not operate the instrument if the protective earth or fuse might be defective. Also, make sure to check them before operation.

Do Not Operate in an Explosive Atmosphere

Do not operate the instrument in the presence of flammable liquids or vapors. Operation in such an environment constitutes a safety hazard.

Do Not Remove the Covers or Disassemble or Alter the Instrument

Only qualified YOKOGAWA personnel may remove the covers and disassemble or alter the instrument. The inside of the instrument is dangerous because parts of it have high voltages.

Ground the Instrument before Making External Connections

Securely connect the protective grounding before connecting to the item under measurement or to an external control unit. If you are going to touch the circuit, make sure to turn OFF the circuit and check that no voltage is present.

IM 701240-01E

Safety Precautions

Precautions to Be Taken When Using the Modules

• Do not apply input voltage exceeding the maximum input voltage, withstand voltage, or allowable surge voltage.

• To prevent the possibility of electric shock, be sure to furnish protective earth grounding of the SL1400.

• To prevent the possibility of electric shock, be sure to fasten the module screws. Otherwise, the electrical protection function and the mechanical protection function will not be activated.

• Do not leave the instrument connected to devices in an environment that may be subject to voltage surges.

Precautions to Be Taken When Using the Probes

• When measuring high voltages using the 701250 (HS10M12) or the 701251 (HS1M16), use the isolated probe (700929), 1:1 safety cable (combination of 701901 and 701954), or differential probe (700924).

• Be sure to connect the GND lead of the differential probe (700924) to the functional ground terminal of the SL1400. High voltage may appear at the BNC connector of the differential probe. Be sure to connect the GND lead to the SL1400 before connecting the probe to the parameter to be measured.

• When using the 701255 (NONISO_10M12), be sure to fasten the module screws. Fastening the module screws activates the protection function and the non-isolation function. It is extremely dangerous if you do not fasten the screws. In addition, when measuring high voltage above 42 V, be sure to use the passive probe (701940).

• The BNC part of the passive probe (701940) is made of metal. Therefore, use the probe at 42 V or less for isolated inputs (701250 (HS10M12), 701251 (HS1M16), etc.) for safety reasons. (Do not connect voltage above 42 V to both the High and Low sides.) For non-isolated inputs (701255 (NONISO_10M12), etc.), fasten the module screws as described before.

• When measuring high voltage using the 701267 (HV (with RMS)), use the measurement leads (758933) and the alligator clips (751954).

• The measurement category of the 701267 (HV (with RMS)) is 400V-CAT II for the low side and 700V-CAT II for the high side. Use caution because the overvoltage tolerance differs between the low and high sides.

Measurement Category

The measurement category of this instrument’s signal input terminals varies depending on the modules that are installed. Use the instrument within the scope of the measurement category that corresponds to the module specifications. Do not use the instrument outside the scope of the measurement category that corresponds to the module specifications.

Installation Location

• This instrument is designed to be used indoors. Do not install or use it outdoors.

• Install the instrument so that you can immediately remove the power cord if an abnormal or dangerous condition occurs.

Signal Flow on the SL1400

The flow of the signal applied to the input signal varies depending on the input module. Here, the high-speed 10 MS/s, 12-bit isolation module (701250 (HS10M12)) is used as an example for the explanation. (For details on the flow of the signal of each module, see the block diagram.) The signal applied to the two input terminals is first processed by the input section of each module. On the 701250 (HS10M12), (1) the attenuator (ATT) attenuates and the amplifier (AMP) amplifies the input signal, (2) the filter (FLT) limits its bandwidth, and (3) the A/D converter samples the input signal at a sample rate of 10 MS/s (10 million times per second) and converts the signal to digital data. Then, the signal passes through the isolator and ASIC and enters the waveform processing ASIC (ACQ-ASIC). The 16 channels of digital data collected at the CPU board passes through the waveform processing ASIC (ACQASIC) and stored in the acquisition memory (ACQ Memory). The digital data stored in the ACQ memory is compressed at high speeds by the waveform processing ASIC (ACQ-ASIC), passes through the graphic controller, and shown on the SVGA TFT color display. The SL1400 can acquire simultaneously up to 16 analog input channels and 16-bit logic data.

2.2 Setting the Horizontal and Vertical Axes

Horizontal (Time) Axis «For procedures, see section 5.2.»

Record Time

When using the internal clock*, the time axis scale is set using the length of time within one screen. The record time is the length of time within one screen. The record time is set in units of second, minute, hour, and day. The transition from seconds to minutes to hours to days is automatically performed. The selectable record time varies depending on the maximum record length installed in the SL1400, the number of channels whose display is turned ON, and the specified sample rate.

* Internal clock and external clock (time base selection)

Under the initial setting, the sampling timing of waveform data is controlled by the clock signal generated from the time base circuit within the SL1400. The sampling timing can also be controlled by a clock signal applied externally. External clock signals are input through the external clock input terminal on the left panel facing the SL1400. This external clock input is useful for observing a signal whose period varies or for observing waveforms by synchronizing to the clock signal of the signal being measured.

T/div

T/div is 1/10th the record time or the time per one grid square (1 div).

Explanation of Functions

Record time 5 ms

10 div

1 div = 500 µs

Record time 10 ms

1 div = 1 ms

Sample Rate

The sample rate is the number of times the measured waveform is sampled (in unit of S/ s). The sample rate is set according to the measurement purpose or the speed of variation. The maximum sample rate varies depending on the module. The SL1400 can display waveforms correctly up to one-half the frequency of the sample rate as defined by the Nyquist sampling theorem.*

* If the sample rate is comparatively low with respect to the input signal frequency, the

harmonics contained in the signal are lost. In this case, some of the harmonics will appear at low frequencies due to the effects described by the Nyquist sampling theorem. This phenomenon is called aliasing. You can prevent aliasing by acquiring waveforms with the acquisition mode set to envelope.

Record length

2.2 Setting the Horizontal and Vertical Axes

Record Length

The term in the acquisition memory. The record length changes when you change the record time or sample rate (see appendix 1). The following equation holds: record length = record time × sample rate. The maximum record length of the SL1400 is 50 MW. The measured waveform signal of a single channel can be acquired up to the maximum record length of 50 MW when only a single channel is displayed. The record length that is stored in the acquisition memory and the record length of the displayed waveform are the same.

record length

Display along the Time Axis

There are 10 divisions along the time axis, and 1001 points (logical number of points, not the dots on the screen) are used to draw the waveforms. Therefore, if the record length is exactly 1 kW (the number of acquired data points is 1001), the waveform is displayed using 1001 points. However, if the record length is greater than or equal to 2 kW, the maxim and minimum values are determined (P-P compression) and aligned at the same time position (total number of points: 2002) to draw the waveform.

Zooming Horizontally and Drawing Waveforms

The SL1400 is capable of expanding (zooming) the waveform horizontally (see page 2-34). When the zoom rate of the waveform is increased, the number of displayed points decreases. The waveform is displayed P-P compressed until the number of display points falls to 2002 points. When the number of displayed points falls below 1001, the waveform can no longer be displayed using continuous lines. In this case, the display data is interpolated using the display interpolation function (see page 2-33) so that the number of displayed points is 1001 points.

2-4

IM 701240-01E

2.2 Setting the Horizontal and Vertical Axes

Dot Display

By default, the display interpolation function works automatically. However, you can also disable the display interpolation in which case the waveform is displayed using dots. In this setting, up to 100100 points (100 kpoints) of the acquired data are displayed without using P-P compression. For example, if the display record length is 10 kW (the number of acquired data points is 10010 points), all the points of the waveform are drawn by aligning 10 points vertically at the same time axis positions. If the number of acquired data points exceeds 100100, only the data per given interval is displayed. In other words, the data is decimated down to 100100 points (100 k points) for displaying the waveform.

Record Time and Roll Mode Display

If the trigger mode is set to Auto, Auto Level, Single, or Log and the record time is set greater than or equal to 1 s/div, the waveform is displayed in roll mode. In roll mode, the displayed waveform is not updated using triggers (update mode). Rather, the oldest data is deleted as new data is acquired, and the waveform is shifted from right to left on the screen.

Explanation of Functions

Roll mode display allows waveforms to be observed in the same way as on a pen recorder. It is useful in observing signals with a long period or signals that change slowly. It is also useful in detecting glitches (spikes in the waveform) that occur intermittently.

2.2 Setting the Horizontal and Vertical Axes

Vertical (Voltage) Axis (for Modules Other Than the Strain Module) «For procedures, see section 5.3.»

Setting the Voltage Range

The voltage range setting is used to adjust the displayed amplitude of the waveform so that it can be easily observed. The voltage range is set using a voltage across the top and bottom edges of the waveform display area (10 divisions). The voltage range changes by switching the input section to an attenuator with different values of attenuation. The sensitivity is changed in steps as in 1 V to 2 V to 5 V.

Measurement Range and Display Range

The measurement range of the SL1400 is ±10 divisions (20 divisions of absolute width (span) around 0 V. The display range of the screen is ±5 divisions (10 divisions of span). The following functions can be used to move the displayed waveform and display the waveform outside the display range by expanding/reducing the displayed waveform.

• Move the vertical position → See page 2-7.

Note

• For measuring the voltage with high accuracy

To measure the voltage with high accuracy, set the voltage range so that the input signal is measured with as large amplitude as possible.

• Measurement Resolution

The measurement resolution varies depending on the module. For example, the 701250 (HS10M12) and 701255 (NONISO_10M12) sample the input signal using a 12-bit A/D converter at a resolution of 150 levels per division. The 701251 (HS1M16), 701267 (HV (with RMS)), 701261 (UNIVERSAL), 701262 (UNIVERSAL (AAF)), 701265 (TEMP/HPV), and 701275 (ACCL/VOLT) sample the input signal using a 16-bit A/D converter at a resolution of 2400 levels per division.

2.2 Setting the Horizontal and Vertical Axes

Vertical Position of Waveforms «For procedures, see section 5.4.»

Since the SL1400 can display the waveforms of the analog input channels (CH1 to CH16) and computation waveforms (Math1 to Math8), the waveforms may overlap making them difficult to be observed. In this happens, you can change the vertical display position of waveforms for easier viewing. The vertical position can be moved within a range of ± 5 div. The voltage sensitivity per division switches around the vertical position mark.

Input Coupling «For procedures, see section 5.5.»

If you want to measure just the amplitude of an AC signal, it is best to remove the DC component from the input signal. On the other hand, there are times when you want to check the ground level or measure the entire input signal (both the DC and AC components). In these cases, you can change the input coupling setting. By changing the input coupling, the input method used to input the signal to the vertical control circuit (voltage axis) is switched. The following types of input coupling are available.

The input signal is directly coupled to the attenuator of the vertical control circuit. Select DC if you want to measure the entire input signal (DC and AC components).

AC (Only When Measuring the AC Voltage)

The input signal is coupled to the attenuator of the vertical control circuit through a capacitor. Select AC if you want to measure only the amplitude of the AC signal, eliminating the DC components from the input signal.

GND

Input signal is coupled to the ground not to the attenuator of the vertical control circuit. By selecting GND, you can check the ground level on the screen.

Using the 701267 (HV (with RMS)), both the DC and AC components of the signal are converted to rms values and displayed. An RMS conversion circuit is connected to the vertical control circuit of the same input coupling circuit used when the coupling is set to “DC.”

Probe Attenuation or Current-to-Voltage Conversion Ratio «For procedures, see section 5.6.»

For voltage (current) measurement, a probe is normally used in connecting the circuit being measured to the signal input terminal. Using a probe has the following advantages.

• Prevents disturbing the voltage and current of the circuit being measured.

• Inputs the signal with no distortion.

• Expands the measurable voltage (current) range of the SL1400.

When using a probe, the attenuation setting on the SL1400 must be set equal to the probe attenuation or current-to-voltage conversion ratio so that the measured voltage (current) can be read directly. The SL1400 has the following attenuation settings: 1:1, 10:1, 100:1, 1000:1, 10A:1V,

and 100A:1V.*2 If you are using a probe other than the ones provided as accessories (sold separately), set the attenuation ratio on the SL1400 according to the attenuation of the probe.

*1 Output voltage rate: 0.1 V/A *2 Output voltage rate: 0.01 V/A

Note

Use a probe that matches the input capacity of each module. Otherwise, the capacity cannot be adjusted.

Bandwidth Limit «For procedures, see section 5.7.»

A bandwidth limit can be applied for each module. By limiting the bandwidth, you can eliminate high frequency components (such as high frequency noise) from the input signal for waveform observation.

Explanation of Functions

Linear Scaling «For procedures, see section 5.11.»

When measuring the voltage (current), strain, or frequency (number of rotations, period, duty cycle, power supply frequency, pulse width, pulse integration, and velocity), there are two methods of linear scaling: “AX+B” and “P1-P2.”

AX+B

Scaling is performed using the specified scaling coefficient A and offset B according to the equation shown below. Cursor measurement values and automated measurement values of waveform parameters are displayed using scaled values. You can also assign a unit to the linearly scaled value.

Y = AX + B (where X is the measured value and Y is the scaling result)

P1-P2

Specify arbitrary scale values (P1:Y and P2:Y) for the measured values of two arbitrary points (P1:X and P2:X). The conversion equation (y = ax + b) is derived from these four values.

Inversion «For procedures, see section 5.12.»

When measuring voltage or strain, the waveform can be displayed with the vertical axis inverted around the vertical position as shown below.

Normal display

Vertical position mark

Pulse/Rotate «For procedures, see section 5.20.»

When the time base is set to external clock, one data sample is captured to the acquisition memory when one pulse of the external clock signal is input. You can specify the number of pulses of the external signal (in other words, the number of data samples captured in the acquisition memory) that will correspond to one mechanical rotation (one cycle). The selectable range is from 1 to 24000 pulses. For example, if the pulse/rotate setting is set to 100 pulses, then 10 rotations of data samples will be acquired when the record length is set to 1 kW. When the pulse/rotate setting is set to 1 pulse, one data sample will correspond to one rotation (one cycle).

The pulse/rotate setting affects only the X-axis (horizontal) measurement values in cursor measurements and the time axis display on the screen. For example, if the pulse/ rotate setting is 100 pulses and the record length is 1 kW, 1 division will be 1 rotation. In this case, moving the cursor by 1 division during cursor measurements causes the horizontal measured value to increase or decrease by “1.”

RMS Measurement «For procedures, see section 5.13.»

If the module of the selected channel is a 701267 (HV (with RMS)), the rms value of the input signal can be observed.

AC-RMS

This setting is used when you want to observe only the rms values of the AC signal, eliminating the DC components from the input signal.

Where u(t) is the input signal and T is one period of the input signal.

Temperature Measurement «For procedures, see section 5.14.»

Thermocouple Types

The following types of thermocouples are available. K, E, J, T, L, U, R, S, B, N, W, and Au7Fe

Selectable Temperature Units

You can select °C or K.

Reference Junction Compensation (RJC)

The voltage generated by a thermocouple depends on the temperature of the spot of measurement and the reference junction temperature. In this case, the function used to compensate the temperature on the measurement instrument side to the cold junction is referred to as reference junction compensation. The SL1400 normally performs reference junction compensation with the built-in RJC circuit. The SL1400 allows you to turn ON or OFF the internal reference junction compensation.

Burnout

This function is used to accurately detect a burnout in the thermocouple. If the thermocouple measurement input detects a burnout, the measured value is fixed to the upper limit of the measurement range of each thermocouple.

Strain Measurement «For procedures, see section 5.15.»

Strain can be measured by connecting a strain gauge bridge (bridge head) or a strain gauge transducer to the strain module (701270 (STRAIN_NDIS) or 701271 (STRAIN_DSUB)).

Relationship between the Strain (µSTR) and the Transducer Output (mV/V)

The SL1400 allows the unit to be changed between “the strain unit (µSTR: ×10–6 strain)” and “the output unit of the strain gauge transducer (mV/V) exists between µSTR and mV/V.

* Unit corresponding to the output of the strain gauge transducer. A value expressing the

transducer output per volt applied to the bridge in mV. You can set the bridge voltage (excitation: voltage applied to the bridge) from 2 V, 5 V, and 10 V. However, since the mV/V value is a converted value, the measured value is basically constant.

mV/V = 0.5×(µSTR/1000)

Example

500 (µSTR) → 0.5×500(µSTR/1000) = 0.25 (mV/V)

Gauge Factor (K) when mV/V Is Selected

You can set the gauge factor to an arbitrary value on the SL1400. However, if there are no specifications on the strain gauge transducer, set K to 2. If K is not 2, e is derived within the SL1400 using the following equation.

e = (4/K)×(V/E)

Shunt Calibration

The 701271 (STRAIN_DSUB) supports shunt calibration.

* Shunt calibration refers to the act of correcting the gain of the strain measurement by

connecting a known resistance (shunt calibration resistance) to the strain gauge in parallel.

For a description of the basic defining equation of strain, see appendix 9. For details on shunt calibration, see appendix 10.

Acceleration Measurement «For procedures, see section 5.16.»

The Acceleration/Voltage Module (with AAF) (701275 (ACCL/VOLT)) measures acceleration using the output signal from the acceleration sensor. Direction connection is possible to a built-in amplifier type acceleration sensor. Direct connection is not possible to a charge output type acceleration sensor that does not have a built-in amplifier.

Current Supply to Acceleration Sensors

The 701275 (ACCL/VOLT) can supply 4 mA of current to the acceleration sensor when measuring acceleration.

Filter

If you set the bandwidth limit to Auto, the anti-aliasing filter (AAF) and low-pass filter are enabled depending on the sample rate to eliminate high-frequency noise from the input signal. Using the anti-aliasing filter when measuring voltage allows elimination of aliasing noise resulting from FFT computation. The filter is effective not only during acceleration measurement but also during voltage measurement.

Deceleration Prediction and Stop Prediction

The 701280 (FREQ) automatically performs internal computation and displays waveforms by predicting the deceleration curve and stop point even when the input pulse is suddenly cut off. This function allows the measurement of waveforms of deceleration behavior that is close to the actual physical phenomenon in applications in which the deceleration behavior of an object that have inertia is measured such as in the brake test of automobiles.

Deceleration Prediction

The deceleration curve is computed according to the following equation using the elapsed time after the pulse input stops (∆t). Frequency (f) = 1/period (∆t) The deceleration prediction starts after a pulse period (T) of the pulse one period before the pulse input stopped elapses after the pulse input stopped.

Stop Prediction

The function determines the stop point at a constant time after the pulse input stops, and the frequency is set to 0. The time from the point when the pulse input stops to the point when the function determines that the object has stopped can be set to ×1.5, ×2, ×3, ... , ×9, and ×10 (10 settings) of the pulse period (T) of the pulse one period before the pulse input stopped.

Smoothing Filter (Moving Average)

The frequency module can display waveforms by taking the moving average of the data in realtime. The order of moving average can be set in terms of time in the range of 0.1 ms to 1 s (up to 25000 specified time divided by 40 µs. The smoothing filter has the following characteristics.

• Converts a waveform that changes in steps to a smooth waveform.

• Improves the resolution by reducing the measurement jitter. The resolution improves especially when measuring high frequencies or when expanding the display using the offset function. Consequently, highly accurate measurements can be made.

• Can be used on all measurement parameters of the frequency module.

Pulse Average

Measures the input pulse by dividing the pulse by the specified number of pulses (1 to 4096 pulses). The pulse average has the following characteristics.

• If pulse dropouts are present or pulse interval is fluctuating within a period, measurements can be made by eliminating the effects from the dropout or fluctuation (fluctuating component of the waveform used to measure the frequency or period).

• The measured result is displayed as a value per input pulse even when pulse average is used. Therefore, there is no need to perform scaling again.

• Can be used when measuring frequency, number of rotations, power supply frequency, pulse integration, and velocity.

•Value/div: 200 Hz/div

Offset Function

The 701280 (FREQ) allows you to set the center of observation (offset value) and expand the area around the offset value for close observation. It allows you to measure the fluctuation around a certain frequency.

Logic Waveforms «For procedures, see section 5.18.»

Logic waveforms can be measured by connecting logic probes to the logic signal input connectors (two connectors marked Logic A and Logic B) on the left side panel. A-1 to A8 (8 bits) and B-1 to B8 (8 bits) can be applied to the Logic A and Logic B ports, respectively.

Wave Window Trigger

This trigger is used to monitor the power supply waveform. It detects abnormalities in the power supply (disruption, sag, surge, frequency fluctuation, voltage drop, etc.). A reference waveform (realtime template) is created by setting a tolerance (window width) to a waveform derived by averaging 1 to 4 cycles of waveforms before the target cycle of the current waveform. The current waveform is compared against the realtime template. If the current waveform falls outside the realtime template, a trigger is activated.

Normally, Sync.Ch is set to Auto (the channel with the smallest number among the modules that can perform wave window trigger).

2.3 Setting the Trigger

Trigger Mode «For procedures, see section 6.1.»

The trigger mode sets the conditions for updating the displayed waveforms. The following six trigger modes are available.

Auto Mode

If a trigger occurs within a specified amount of time (approximately 50 ms, referred to as the timeout period), the displayed waveforms are updated. If a trigger is not activated within the timeout period, the displayed waveforms are automatically updated.

Auto Level Mode

Within the timeout period (approximately 1 s), the waveforms are displayed in the same fashion as in the auto mode. If a trigger is not activated within the timeout period, then the center value of the amplitude of the trigger source is detected, and the trigger level is changed to that value. A trigger is activated using the new value, and the displayed waveforms are updated.

Normal Mode

The waveform display is updated only when a trigger occurs. (The displayed waveforms are not updated if a trigger does not occur.)

1/2 the amplitude

Trigger level Amplitude

1/2 the amplitude

Single Mode

When a trigger is activated, the displayed waveforms are updated only once, and acquisition stops. This mode is suitable for observing a single-shot signal.

Single (N) Mode (Sequential Store Function)

This mode is selected when using the sequential store function (see section 2.4). Waveforms are acquired and stored in different memory areas each time a trigger is activated the specified number of times. Then, acquisition is stopped, and all the acquired waveforms are displayed. Acquired waveforms can be displayed together, or they can be displayed individually. This mode is useful for detecting sudden abnormalities in a waveform.

Acquisition Mode «For procedures, see sections 7.2 and 7.3.»

When storing sampled data in the acquisition memory, it is possible to perform processing on data and display waveforms based on the processed data. The following four types of data processing are available.

Normal Mode

In this mode, sampled data are stored in the acquisition memory without data processing.

Averaging Mode

Averaging

average of waveform data at the same time point (the same time in relation to the trigger point). The SL1400 takes the simple or exponential average of the waveform data and writes the results to the acquisition memory. The averaged data is then used to generate the display. You can set the attenuation constant to a value between 2 and 256 (in 2 where n is a natural number) and the averaging count to a value between 2 and 65536.

Averaging is effective such as when eliminating the random noise riding on the signal.

Envelope Mode

In normal mode and averaging mode, if you increase the record time, you must reduce the sample rate (the number of times data is acquired per second in the acquisition memory) to keep the record length of the acquisition memory the same (see appendix 1). However, in the envelope mode, the maximum and minimum values are determined at every time interval from the data sampled at the maximum sample rate of each input module. The time interval used to determine the values is twice the sample rate of the normal mode. The maximum and minimum values are paired and stored in the acquisition memory. Envelope mode is effective when you want to avoid aliasing, since the sample rate is kept high irrespective of the time axis setting. It is also effective when you want to detect glitches (pulse signals which rise very fast) or display an envelope of a modulating signal.

This mode is valid on the 701250 (HS10M12) and 701255 (NONISO_10M12). The rolling average of the data sampled at the maximum sample rate is determined. The resultant data is stored in the acquisition memory and used to generate the display. Box averaging is effective in eliminating small amounts of noise from the input signal. It can also remove noise from a single-shot signal.

Sequential Store «For procedures, see section 7.4.»

In the case of the history memory function describe in the next subsection, the waveform data of each block is updated in order until the measurement is stopped. However, in the sequential store function, you specify the waveform acquisition count (number of blocks), and the measurement stops when the specified count is reached. The updating of the waveform display is carried out after acquiring the entire waveform data. To acquire waveforms using this function, set the trigger mode to Single(N). The maximum Single(N) count is equal to N that is explained in the history memory function. The stored waveform data can be recalled using the history memory function. The figure below shows an example when data is sequentially stored 100 times.

Display example when the acquisition count is 100

2.4 Setting Waveform Acquisition Conditions and Display Conditions

History Memory «For procedures, see section 11.1.»

If the record length is set short on the SL1400, the memory is divided into blocks, and waveform data is saved to the individual blocks each time a trigger occurs. If N represents the maximum number of blocks determined by the record length, the oldest waveform data block is cleared when the number of activated triggers exceeds N. If you stop the measurement, you can recall the waveform data stored in each block and display the data on the screen. Once the specified number of waveforms have been stored, you can display any of the waveforms individually or all of them together. This function is useful when capturing the changes in the waveform over time. The following figure indicates an example when N = 100.

2.4 Setting Waveform Acquisition Conditions and Display Conditions

Realtime Recording to the Internal Hard Disk (Option) «For procedures, see section

7.5.»

The data can be recorded in realtime to the internal hard disk (option). The stored data can be recalled. The realtime recording area is allocated on the internal hard disk in advance (the default value is 50% of the entire capacity of the internal hard disk). You can set the realtime recording area in the range of 30% to 70% of the entire capacity of the internal hard disk when you format the internal hard disk (see section 13.6).

The time axis range and the maximum sample rate that allow realtime recording vary depending on the number of channels to be recorded in realtime. For details, see appendix 3.

The following two modes of realtime recording operation are available. Single: Starts realtime recording with the start of waveform acquisition and stops

realtime recording when the specified record time is reached.

Continue: Starts realtime recording with the start of waveform acquisition and stops

realtime recording when the specified record time is reached. This sequence is repeated the specified number of times (count).

If you select Single, Auto or Log trigger modes are available. If you select Continue, only Log is valid. Auto: Acquisition is started by pressing START. If the specified record time is

exceeded, old data is overwritten. Acquisition continues until you press STOP.

Action-on-Stop «For procedures, see section 7.6.»

A specified action can be carried out when the waveform is displayed after acquiring the specified record length of data after the measurement is started or when measurement is stopped. The following five types of actions are available.

Print the Screen Image Data (PRINT)

Prints the screen image to a specified printer.

Save the Screen Image Data (Image)

Saves the screen image data to the save destination specified in the IMAGE menu.

Save Waveform Data (Save to File)

Saves the waveform data in binary, ASCII, or floating format to the save destination specified in the FILE menu.

Beep Sound (Buzzer)

Sounds a buzzer.

Send Mail

Sends an e-mail message to a specified address (when Ethernet interface option is installed).

Backing Up the Acquisition Memory «For procedures, see section 7.7.»

If the ACQ MEMORY BACKUP switch on the right side panel of the SL1400 is turned ON, the history memory data in the acquisition memory is backed up even when the power supply is cut off. The data held in the acquisition memory is backed up immediately before the power is turned OFF. This function protects the data in the acquisition memory from sudden power failures. Alkaline dry cells or nickel hydride rechargeable batteries (four AAA batteries) are required for the backup. The backup time varies depending on the operating environment. For reference values of the backup time, see section 18.5.

Display Format and Waveform Mapping «For procedures, see section 8.1.»

Display Format

Waveforms can be displayed in divided windows to facilitate the viewing of multi-channel waveforms and computed waveforms.

Waveform Mapping

You can select the mapping of the input channels to the divided windows from the following: Auto: The input channels whose display is turned ON are assigned in order by the

channel numbers.

Fixed: Waveforms are assigned in order from the top regardless of whether the input

channel display is turned ON/OFF.

User: The channels can be assigned arbitrarily to the divided windows regardless of

whether the input channel display is ON/OFF.

2.4 Setting Waveform Acquisition Conditions and Display Conditions

Display Interpolation «For procedures, see section 8.2.»

In areas where less than 1000 points of data exist in the 10 divisions along the time axis (referred to as interpolation areas), a continuous waveform cannot be displayed because there is not enough sampled points. In this case, waveform is displayed by interpolating between data points. You can select the interpolation method from the following:

Linear Interpolation

Linearly interpolates between two points.

Sine Interpolation

sin x

Generates interpolation data using the function sin(x)/x then interpolates between

two dots using the resulting sine curve. Sine interpolation is suitable for observing sine waves or similar waves.

Interpolation OFF

Displays discrete dots without performing interpolation.

Linear Interpolation Sine Interpolation Interpolation OFF

Explanation of Functions

If the interpolation is OFF, waveforms are displayed using dots. In this setting, up to 100100 points (100 kpoints) of the acquired data are displayed without using P-P compression (page 2-4). For details, see page 2-5.

Graticule «For procedures, see section 8.3.»

You can change the type of graticule that is displayed to suit your needs. For example, you can show a grid on the screen or show only the frame.

Accumulated Display «For procedures, see section 8.4.»

This mode holds each waveform on the screen for a time that is longer than the update cycle, so that newer waveforms appear overlapped on older waveforms. If you select Persist, the waveforms are accumulated. Accumulated display is useful when you want to observe jitters and temporary turbulence in waveforms. Accumulated display is also possible on waveforms that are recalled using the history memory function.

IM 701240-01E

2.4 Setting Waveform Acquisition Conditions and Display Conditions

Zooming in on the Waveform Horizontally «For procedures, see section 8.5.»

The displayed waveform can be expanded along the time axis. This function is useful when the waveform acquisition time is set long and you want to observe a particular section of the waveform closely. Zooming is not possible if the number of displayed points on the screen is less than or equal to 10 (less than or equal to 50 for FFT waveforms). The zoom position is set in units of divisions of the grid.

Display Format When the Waveform Is Zoomed

Zoomed waveforms of two locations can be displayed simultaneously (dual zoom). Below are the combinations of the display methods of zoom waveforms. Main: Main waveform display frame Z1, Z2: Zoom waveform display frame

<Main>

<Main>

<Z1>

<Z2>

When displaying Main (main waveform) and Z1 or Z2 (zoomed waveform) simultaneously, a zoom box indicating the zoom position is displayed within the main waveform display frame. The center of the zoom area corresponds to the center of the zoom box.

Z1 box

Main waveform display frame

2.4 Setting Waveform Acquisition Conditions and Display Conditions

X-Y Waveform «For procedures, see section 8.6.»

The voltage relationship between signals can be observed by assigning the voltage of the input signal of the specified channel on the horizontal axis (X-axis) and the voltage of another input signal (signal that has the display turned ON) on the vertical axis (Y-axis). Simultaneous observation of X-Y waveforms and normal T-Y waveforms (waveform display using voltage axis and time axis) is possible. You can use the X-Y waveform display function to measure the phase angle between two sine wave signals. For example, the waveform that appears when two sine waveforms are shown on the X-Y display is called a Lissajous waveform. From this waveform, the phase angle can be read.

Snapshot «For procedures, see section 8.7.»

If the trigger mode is set to a mode other than single, the displayed waveforms are periodically updated or displayed in roll mode. The snapshot function allows you to temporarily hold the waveform that would be cleared when the screen is updated (snapshot waveform) on the screen. The snapshot waveform is displayed in white, allowing for easy comparison against the updated waveform. The snapshot waveform is a screen image waveform. You can save, load, and print the screen image data, but cursor measurements, automated measurement of waveform parameters, zoom, and computation cannot be performed on it.

Snapshot waveforms

Clear Trace «For procedures, see section 8.7.»

You can clear the snapshot waveform and restart averaging and accumulation using one key operation. Pressing the CLEAR TRACE key temporarily clears the measured waveforms from the screen. Pressing the ESC key redisplays them.

Scale Values «For procedures, see section 8.9.»

The upper and lower limits (scale values) of the vertical and horizontal axes of each channel can be displayed.

Waveform Labels «For procedures, see section 8.10.»

A waveform label can be assigned arbitrarily to the input waveform of each channel using up to eight characters.

Extra Window «For procedures, see section 8.11.»

This area displays data such as cursor measurement values and values resulting from automated measurement of waveform parameters. The extra window is useful when reading of the values is difficult because waveforms are overlapping them.

Level Indicators «For procedures, see section 8.12.»

The level of each waveform is displayed using an indication mark to the right of the waveform display frame.

Channel Information, Numeric Monitor, and Waveform Display Area Expansion «For procedures, see section 8.13.»

If you clear the setup menu by pressing ESC, channel information is displayed such as the voltage/division, input coupling, probe attenuation (type), bandwidth limit, temperature/division , thermocouple type, µSTR/division (or [mV/V]/division), measurement range, acceleration/div, gain, bias, value/division, measurement mode, and preset settings. However, some items are skipped when the number of displayed channels increases.

Pressing ESC once when the channel information is displayed clears the channel information and shows the numeric monitor.

Pressing ESC once when the numeric monitor is displayed expands the waveform display area horizontally to cover the entire screen.

2-36

If you press SELECT when the channel information or waveform monitor is displayed or when the waveform display area is expanded and an item is under jog shuttle control in the setup menu that was showing immediately before you pressed ESC, the item is displayed at the upper right of the display and can be controlled using the jog shuttle.

2.5 Recording in Recorder Mode

The SL1400 is equipped with an A-4 size printer. If Chart Recorder mode is selected in the menu that appears when MODE is pressed and waveform acquisition is started, T-Y waveforms (T-Y waveform recording) or numeric values can be recorded in realtime. In addition, if X-Y Recorder mode is selected and waveform acquisition is started and stopped, the X-Y waveform over the interval in which waveform was acquired can be recorded (X-Y waveform recording).

Chart Recorder Mode «For procedures, see sections 9.1 to 9.5.»

Print Style

In Chart Recorder mode, the print style can be selected from the following two styles.

T-Y Waveform Recording

In T-Y waveform recording, recording is performed at the specified chart speed (10 mm/h to 20 mm/s). The scale used in T-Y waveform recording is fixed to 10 mm per division on the horizontal axis (time axis). The scale on the vertical axis (voltage axis) can be set to 10 mm per division or [1 division of the 10 equally divided chart recording zone] per division. The recording can also be stopped automatically after recording a specified length (shot recording).

Numeric Value Recording

Numeric values can be recorded at the specified time interval (1 s to 60 min). Up to 16 channels can be recorded. If waveform acquisition is started on more than 16 channels, 16 channels are recorded in the following order: CH1 to CH6, Logic A, and Logic B.

Explanation of Functions

Acquisition Mode during Chart Recorder Mode

During Chart Recorder mode, the acquisition mode is set to envelope. The acquisition mode cannot be changed using the ACQ menu as with the normal operation. However, the acquisition mode can be changed to normal using other menus. Select normal mode if you are using the acquired waveform as numeric data such as in an analysis.

Selectable Trigger Modes in Chart Recorder Mode

The following four trigger modes are available.

2.5 Recording in Recorder Mode

Saving Data in the Internal Memory

In Chart Recorder mode, up to 1000 divisions of the recorded data are automatically saved in the internal memory. The required section of the data that has been cleared from the screen can be redisplayed after the recording is finished by using functions such as zoom (limited to the data in the range defined by “Number of Data Points That Can Be Saved” below). As with the normal data (data when the recorder mode is OFF), cursor measurements, automated measurement of waveform parameters, normal statistical processing*, zoom, and display setting modification in the DISPLAY menu can be performed on the redisplayed data. The redisplayed data can also be saved as waveform data in the same fashion as normal data. Furthermore, the redisplayed data can be reprinted by changing the print conditions or a PDF file of the reprint image can be created (see “Reprinting on the Built-in Printer” or “Creating a PDF File of the Reprinted Image” on page 2-40).

* Cyclic statistical processing and statistical processing of history data cannot be performed in

Chart Recorder mode.

Number of Data Points That Can Be Saved

If the chart speed is slow, the number of data points that can be saved in the internal memory is reduced. For example, if the chart speed is 10 mm/h, up to 100 divisions of data (up to 4 days of data) are saved. If the chart speed is 20 mm/s, up to 1000 divisions of data (up to 8 minutes 20 seconds of data) are saved. The maximum number of divisions that can be saved for each chart speed is as follows:

Chart Speed Maximum Number of Divisions That Can Be Saved

20 [mm/s] to 1 [mm/s] 1000 100 [mm/min] to 2 [mm/min] 1000

1 [mm/min] 500 100 [mm/h] 1000

For the relationship between the chart speed and sample rate, see appendix 2.

Functions That Cannot Be Used in Chart Recorder Mode

When making measurements in Chart Recorder mode, functions of history memory and waveform computation cannot be used (The HISTORY key and MENU key > MATH menu cannot be used).

Measured Data Compatibility

The measured data in Chart Recorder mode is not compatible with the measured data in Memory mode. The measured/saved data in Chart Recorder mode cannot be loaded in Memory mode, and vice versa.

2-39

2.5 Recording in Recorder Mode

X-Y Recorder Mode «For procedures, see section 9.6.»

X-Y Waveform Recording:

In X-Y waveform recording, the X-Y waveform display starts when waveform acquisition is started. If reprint is executed from the Reprint Setup menu after the record length of waveform (fixed to 1 MW) is acquired or after stopping waveform acquisition, the X-Y waveform acquired up to the point immediately before the measurement was stopped is recorded on paper. The scale of the X-Y waveform recording is 10 mm per division for both X- and Y-axes, and the waveform recording area is ±10 divisions (20 divisions). The screen also shows the X-Y waveform. Recording to paper can also be started automatically when waveform acquisition is stopped (auto print).

Acquisition Mode during X-Y Recorder Mode

The acquisition mode is automatically set to normal mode during X-Y record mode. The acquisition mode cannot be changed using the Menu key > ACQ menu as with the normal operation.

Saving Data in the Internal Memory

In X-Y recorder mode, up to 1 MW of data is automatically saved in the internal memory. Also, a PDF file of the reprint image can be created.

Functions That Cannot Be Used during X-Y Recorder Mode

When making measurements in X-Y Recorder mode, functions of history memory and waveform computation cannot be used (The HISTORY key and MENU key > MATH menu cannot be used). In addition, items set using the MENU key > ACQ menu cannot be changed.

Measured Data Compatibility

The measured data in X-Y Recorder mode is not compatible with the measured data in Memory mode. The measured/saved data in X-Y Recorder mode cannot be loaded in Memory mode, and vice versa.

Reprinting on the Built-in Printer (Only during T-Y Recording) «For procedures, see section 9.7.»

After the T-Y recording in Chart Recorder mode is finished, the data stored in the internal memory can be recalled and reprinted by changing the print conditions.

Creating a PDF File of the Reprint Image «For procedures, see section 9.8.»

After the waveform recording in Chart Recorder mode or X-Y Reorder Mode is finished, the data stored in the internal memory can be recalled and a PDF file of the reprint image can be created. In X-Y Recorder Mode, the most recent 1 MW of data stored in the internal memory are output to the PDF file. If data exceeding 1 MW is recalled, the waveform displayed on the screen and the waveform recorded on the printer may differ from the waveform output to the PDF file.

2.6 Waveform Computation

Various computations can be performed on up to 800 kW of data on the SL1400. (If a waveform greater than 800 kW is displayed, computation cannot be performed over all the data at once.) The computed results become Math1 to Math8 waveforms.

Addition, Subtraction, Multiplication, and Division «For procedures, see section 10.1.»

Addition, subtraction, multiplication, and division can be performed between two arbitrary waveforms of CH1 to CH16 and Math1 to Math7. These computations are useful in the following cases. Addition and subtraction: Comparison with the standard signal, confirmation of the

signal logic, phase comparison, etc.

Multiplication and division: Confirmation of the power waveform by applying the voltage

and current signals, etc.

Explanation of Functions

Binary Computation «For procedures, see section 10.2.»

The specified waveform is converted to a digital waveform of 0s and 1s with respect to the specified threshold level. The computation can be performed on CH1 to CH16 and Math1 to Math7.

Power Spectrum Display «For procedures, see section 10.3.»

The power spectrum of the input signal can be displayed by taking the FFT (Fast Fourier Transform). This is useful when you wish to check the frequency distribution of the input signal.

Power spectrum waveform

Waveform to be computed

Computed waveform

The following three FFT windows are available.

Rectangular (Rect)

The rectangular window is best suited to transient signals, such as impulse waves, which attenuate completely within the time window.

Hanning and FlatTop

The Hanning and flattop windows allow continuity of the signal by gradually attenuating the parts of the signal located near the ends of the time window down to the 0 level. Hence, it is best suited to continuous signals. With the Hanning window, the frequency resolution is high compared to the flattop window. However, the flattop window has a higher level of accuracy. When the waveform being analyzed is a continuous signal, select the proper window for the application.

2.6 Waveform Computation

FFT is performed on 1000, 2000, 5000, 10000, 20000, 50000, or 100000 points of measured data. The data is converted to half the specified number of points and displayed.

Phase Shift «For procedures, see section 10.4.»

You can shift the phase of CH1 to CH16 and Math1 to Math7 waveforms and display the resultant waveforms or perform computation using the phase-shifted data.

: W(t) = u(t) – u(t – T) U(t): Step function

: W(t) = 0.5 – 0.5 cos(2 π )

: W(t) = {0.54 – 0.46 cos(2 π )}

2 π(1 – 2t/T)

Scaling of Computed Waveforms «For procedures, see chapter 10.»

Normally, the SL1400 performs auto scaling when computed waveforms are displayed. However, you can also select manual scaling. When auto scaling, the upper and lower limits suitable for displaying the waveform are determined from the first computed waveform. If you select manual scaling, you can arbitrarily set the upper and lower limits of the computed waveform display.

You can display a specified history waveform from the data (up to 2000 waveforms, or the number of triggers) stored in the acquisition memory. The number of waveforms N that can be acquired and held as history waveforms varies from 1 to 2000 depending on the record length and acquisition mode settings. The waveform currently displayed on the screen (most recent waveform) is counted as the 1st waveform, and up to N–1 waveforms in the past can be displayed.

History Search «For procedures, see sections 11.2 and 11.3.»

• After turning the power off, wait at least 10 seconds before you turn it on again.

• It takes several seconds for the startup screen to appear.

Power Down Operation

Settings existing immediately before the power is turned OFF (also if the power cord is removed) are retained. This allows measurements to be performed using those saved settings the next time the power is turned ON.

Note

The settings are stored using an internal lithium battery. The battery lasts for approximately 5 years, if it is used at an ambient temperature of 23°C. When the lithium battery voltage falls below a specified level, a message is displayed on the screen (error 907) when the power switch is turned ON. If this message appears frequently, the battery must be replaced quickly. The user cannot replace the battery. Contact your nearest YOKOGAWA dealer to have the battery replaced.

To Make Accurate Measurements

• Allow the instrument to warm up for at least 30 minutes after turning ON the power switch.

• After warm-up is complete, perform calibration (see section 4.6). If auto calibration is

3.5 Loading the Roll Paper for the Built-in Printer

Printer Roll Paper

Use a dedicated roll paper that is provided by YOKOGAWA. Do not use other types of roll paper. When you are using the printer for the first time, use the roll paper that came with the package. Order extra rolls from your nearest YOKOGAWA dealer.

Part number: 701966 Specifications: Thermal paper, 20 m Minimum Q’ty: 6 rolls

Roll Paper Handling

The paper is a thermal paper that changes color with the application of heat. Note the following:

Storage Precautions

The paper starts changing color at around 70°C. It is affected by heat, humidity, light, and chemicals regardless of whether the paper has been used.

• Store the paper rolls in a cool, dry, and dark place.

• After opening the package, use it quickly.

• If the paper is left in contact with plastic film containing plasticizers (such as a vinyl chloride film or cellophane tape) for an extended time, the paper will lose some of its ability to reproduce color. If you are going to store the paper in a folder, for example, use a folder made of paper stock or polypropylene.

• When using glue on the paper, do not use glue containing organic solvents such as alcohol or ether, as they will change the color of the paper.

• For prolonged storage, we suggest you make copies of results printed on the roll paper. Due to the characteristics of the thermal paper, the recording section may lose color over time.

Handling Precautions

• Be sure to use only genuine paper rolls provided by YOKOGAWA.

• Touching the paper with sweaty hands can leave finger prints or blur the printing.

• Rubbing the surface with a hard object can cause the paper to change color due to the heat caused by friction.

• If chemicals, oil, or other liquids come in contact with the paper, the paper may change color or the printing may fade.

Precautions to Be Taken When Using the Built-in Printer

Allow enough space around the output area of the printer. If the roll paper is continuously fed out when the output area is close to a wall, for example, the roll paper that has been delivered may reenter the output area and get entangled.

Over-Range Indication

If over-range is indicated, the SL1400 may be receiving a voltage higher than the observed waveform or measured waveform values. To prevent electric shock, change the vertical scale with the RANGE knob so that the entire amplitude of the waveform is displayed within the waveform display area, and check the input voltage level.

Over-range indication

Indicates the number of the channel that over-range is occurring on. If over-range is occurring on multiple channels, the smallest channel number among them is indicated.
