3. Notes for Safe Operation

(1) Be sure to use the Graphtec-supplied AC power cable. In environments where there is a lot of noise or

where the power supply is unstable, we recommend that you ground the WR300 Series.

(2) When a high-voltage signal cable has been connected to the main unit's analog signal input terminal,

avoid touching the leads of the input terminal's signal cable to prevent electrical shock due to high voltage.

(3) Ensure that the WR300 Series power source is positioned so that it can easily be disconnected.

4. Notes on Functions and Performance

(1) Be sure to connect the main unit to an AC or DC power supply that conforms to the rated range.

Connection to a non-rated power supply may cause the main unit to overheat and break down.

(2) Do not block the vent on the main unit.

Continued operation with the vent blocked may cause the main unit to overheat and break down.

(3) To avoid malfunctions and other damage, avoid using the WR300 Series in the following locations.

• Places exposed to high temperature and/or high humidity, such as in direct sunlight or near heating equipment. (Operating range - Temperature: 0 to 40°C, Humidity: 30 to 80% RH)

• Locations subject to excessive salt spray or heavy fumes from corrosive gas or solvents.

•Excessively dusty locations.

• Locations subject to strong vibrations or shock.

• Locations subject to surge voltages and/or electromagnetic interference.

(4) Use the chart paper supplied by Graphtec. The print quality cannot be guaranteed if other paper types

are used.

(5) If the main unit becomes soiled, wipe it off using a soft, dry cloth. Use of organic solvents (such as

thinner or benzene) causes deterioration and discoloration of the outer casing.

Introduction

(6) In the course of use, the thermal head gradually becomes soiled which will lower the print quality. If this

happens, it is recommended to clean it using the optional B-368 head cleaner kit. If the print quality does not improve even after using the head cleaner, contact your sales representative or nearest Graphtec vendor.

(7) Do not use the WR300 Series in the vicinity of other devices which are susceptible to electromagnetic

interference.

(8) Measured results may not conform to the stated specifications if the WR300 Series is used in an

environment which is subject to strong electromagnetic interference.

(9) Insofar as possible, position the WR300 Series input signal cables away from any other cables which

are likely to be affected by electromagnetic interference.

(10)For stabilized measurement, allow the WR300 Series to warm up for at least 30 minutes after turning it

on.

Configuration When in Use

The WR300/310 must always be laid flat when in use.

WR300-8

CAUTION

Do not block the air vent on the WR300/310, as this will cause malfunctioning.

1-3

General Description

1.4 Notes on Temperature Measurement

Please observe the following precautions when using the WR3-M AMP (voltage/temperature amp) to perform temperature measurement.

(1) Do not block the air vents. Always provide a space of at least 30 cm on all sides of the WR300/310. (2) For stabilized temperature measurement, allow the WR300/310 to warm up for at least 30 minutes after

turning it on.

(3) Exposure of the WR3-M AMP's (voltage/temperature amp) input terminals to direct drafts, direct sunlight,

or abrupt changes in temperature may impair the equilibrium of the input parts and result in measurement errors. To measure temperature in such an environment, take appropriate countermeasures such as changing the installation site of the WR300/310.

1.5 Notes on Using the Monitor

The monitor is an LCD display unit, and so the display will vary depending on the operating environment.

CHECKPOINT

If the screen saver function is used, it will operate and clear the screen if no operations are performed during the preset time. If the screen saver operates, press any key to restore the display.

CAUTION

• Condensation may form on the LCD screen if the WR300/310 is moved from a cold to a warm location. If this occurs, wait until the LCD screen warms up to room temperature.

• The LCD screen is manufactured to extremely high precision. Black dots may appear, or red, blue, and green dots may not disappear. Likewise, streaks may appear when viewed from certain angles. These phenomena are due to the LCD screen construction, and are not signs of a fault.

1.6 Changing the Display Language

You can choose English, French, or Japanese as the language displayed on the screen. The default display language is set to English (US) when the WR300/310 is shipped overseas. To change the display language, see the instructions in "Changing the Display Language".

1.7 Protecting the Thermal Head

This recorder is provided with a circuit for protecting the thermal printhead. When the solid-fill area of recording is large, this circuit protects the thermal printhead by lowering the print density so that current above a stipulated level will not flow to the thermal printhead. As soon as the solid-fill area of recording is decreased, the print density automatically resumes its usual level. In the event that the print density fluctuates too often, reduce the solid-fill area of recording by such means as changing the Record Format setting, lowering the print density, and so on.

When the Capture Destination is Memory When the Capture Destination is Disk

[Common Settings]: These are the common settings for capturing measured data.

(1) Capture Destination.. Selects the destination for saving measured data.

Memory : Saves the measured data in the recorder's internal memory. Disk : Saves the measured data to an internal hard disk (WR310 only) or

PCMCIA card.

CHECKPOINT

Disk cannot be selected in FFT mode or when the Waveform Display mode is XY.

(2) Sampling Interval...... Selects the interval for sampling data during measurement. The window shows the

Sampling Interval as a time interval (on the left) and a frequency (on the right). Available settings vary with the Capture Destination setting.

CHECKPOINT

• When different types of amps are installed and measurement is conducted using the fastest Sampling Interval setting of the amp with the highest Sampling Interval setting, each amp with a slower Sampling Interval setting will sample data using its own fastest Sampling Interval setting and any data between its own sampling intervals will be regarded as measured data of identical value.

• However, if an M amp is installed and you have selected TEMP for the input for even just one channel, the maximum sampling interval will be 10 µs.

Maximum Capture Speeds When Capturing Data to Memory

When the Capture Destination is Memory, the maximum data capture speed is the maximum sampling interval for the amplifier:

• WR3-V amp : 1 µs• WR3-M amp : 10 µs

• WR3-DCB amp : 10 µs• WR3-FV amp : 4 µs

• Logic amp : 1 µs

Recorder Mode

Maximum Capture Speeds When Capturing Data to Disk

The maximum capture speed when capturing data to disk varies depending on the maximum sampling interval, the number of channels, and on the memory device. When data capture is performed at a Sampling Interval setting higher than those listed in the table, some of the measured data may be skipped during data capture. If this happens, the "Skipped" message and a count of the number of data points skipped appear at the bottom of the Monitor window during data capture. In such case, change the Sampling Interval setting to a lower value.

CHECKPOINT

To ensure optimum data capture at the specified sampling interval, or if skipping occurs frequently during data capture, save your data files to another memory device and then reformat the disk.

(3) Time Scale................ Sets the time per division on the screen

(4) Program Block .......... This parameter can only be set when the Capture Destination setting is Memory.

When the Block Size setting is other than 1MW x 1, set the Program Block setting to Reserve before using one of the functions for calculation or the Waveform Judgment function, which will cause the final Memory Block No. to be used as the destination for saving the result of a calculation.

CHECKPOINT

When the Program Block setting is Reserve, even if the final Memory Block No. contains data, such data will be overwritten.

[Data Memory Settings]: These are the settings for capturing data to the internal memory.

(5) Block Size................. This parameter, which can only be set when the Capture Destination setting is

Memory, selects the number of blocks in the WR300/310's internal memory. By partitioning the internal memory according to the amount of time spent on measurement, you can change the capacity of the internal memory.

1 MWord x 1, 512 kWords x 2, 256 kWords x 4, 128 kWords x 8, 64 kWords x 16, 32 kWords x 32, 16 kWords x 64, 8 kWords x 128

(6) Capture Time............ This parameter, which is only displayed when the Capture Destination setting is

Memory, indicates the time required for capturing data in the WR300/310's internal memory. The total time equals the Sampling Interval setting multiplied by the Block Size setting.

Example:

Sampling Interval : 4 µs Block Size : 8 kW x 128 Capture Time : 8 kW x 4 µs x 1 = 32 ms

3-9

Recorder Mode

(7) Memory Chain .......... This parameter, which can only be set when the Capture Destination setting is

Memory, selects the method for capturing data in partitioned memory blocks. Off : Repeatedly captures data to the specified Block No. Sequential Block : Repeatedly captures and overwrites data in ascending order

from the specified Block No. (proceeding to Block 1 after the highest Block No.) until measurement is completed.

Empty Block : Captures data in ascending order from the specified Block No.

(proceeding to Block 1 after the highest Block No.), terminating data capture when no empty blocks remain.

(8) Stat. Calc. ................. This parameter selects the On/Off status of statistical calculation, provided that

both of the following conditions are met:

• The Capture Destination setting is Memory; and

• The Block Size setting is other than 1 MW x 1. Arithmetic averaging is used as the method for statistical calculation. Statistical

calculation calculates the arithmetic mean between the data captured in the specified Memory Block (which varies with the Memory Chain and Memory Block settings) and the data captured at the final Block No., and then saves the calculated result at the final Block No. This operation is performed the number of times specified by the Number of Means parameter.

Available Settings Off : Disables statistical calculation. On : Enables statistical calculation. When On is selected, a submenu appears for

setting the frequency of arithmetic averaging.

CHECKPOINT

•

The result of a Statistical Calculation operation will be saved to the final Memory Block No.

• Data captured to the specified Memory Block is constantly overwritten so that only the most recent data is saved. Please note that earlier data will not be retained.

(9) Auto Save ................. This parameter, which can only be set when the Capture Destination setting is

Memory, selects the On/Off status of the Auto Save function. When Auto Save is On, the data captured in internal memory is automatically saved to the PCMCIA card or to the built-in hard disk.

CHECKPOINT

• A block containing data and an empty block can be distinguished by the color used to display them.

Block No.

Green :A block containing data. Gray : An empty block Blue : A block containing the result of a calculation operation and so forth.

• To erase captured data, change the setting of the block size. All the captured data will be erased.

[Data Disk Settings]:These are the settings for capturing data to the hard disk (WR310 only) or PCMCIA

card.

(10) File Name (Disk)..... This parameter can only be specified in the following case:

• Either a hard disk drive or a PCMCIA card drive is installed; and

• The Capture Destination setting is Disk. This parameter specifies the destination folder, and destination file name. The

extension differs according to the save destination as follows: PCMCIA card : ".GBD" HDD : ".GDT"

CHECKPOINT

If you have selected Memory, data is captured to the Capture Destination in the Memory Settings menu.

(2) Time Gate................. Specifies the wait time for the trigger signal.

CHECKPOINT

The Time Gate setting only affects the [Start Condition] and cannot be used for the [Stop Condition]. The timing of the Time Gate function is based on the WR300/310's internal clock.

Disable : Disables the Time Gate function. Relative Time : Specifies the interval for awaiting trigger signal input as a relative

time period which begins when the START key is pressed. When this setting is selected, a submenu for setting the time interval appears.

Absolute Time : Specifies the time wait interval as absolute starting and stopping

times. When this setting is selected, a submenu for setting the time interval appears.

• Set Time : Can only be set when the Time Gate setting is Relative Time or Absolute Time.

• Set Mode : Selects the mode for setting the Time Gate parameter's wait interval.

Start Time : Enables only the starting time. Start & Stop : Enables the starting and stopping times.

CHECKPOINT

• When the Time Gate setting is Relative Time, both the starting and ending times must be specified relative to the starting time of measurement in the range of 0000:00:01 to 9999:59:59 (hours:minutes:seconds).

• Lower - Level - Upper

........................ Specifies the trigger level for the input signal in a range from 0 to 100% (Lower

SPAN limit: 0%, Upper SPAN limit: 100%).

When the Mode setting is ↑/H or ↓/L:

Specify one Trigger Level in the range of -100% to +100% in 1% steps (where the current Range setting's lower limit is -100% and its upper limit is +100%). Example :When the Range setting is 5V

-5V equals -100%, and +5V equals +100%.

When the Mode setting is Win In or Win Out:

Specify two Trigger Levels in the range of -100% to +100% in 1% steps (where the current Range setting's lower limit is -100% and its upper limit is +100%). Specify the upper and lower limits so that the difference between them is at least 5%. Example :When the Range setting is 5V

-5V equals -100%, and +5V equals +100%.

The Logic setting (only if a logic amp is installed):

X :Excludes the logic amp's channels as trigger channels. L :Activates the trigger at Low-level signal input. H :Activates the trigger at High-level signal input.

CHECKPOINT

The permissible range of the logic amp's L and H values varies with the Threshold setting in the AMP Settings window.

• Trigger Counter.......Can only be set when the Combination setting is Level OR or Level AND. When the

recorder is in trigger armed status, this function can be set to make the recorder ignore trigger signal input during a fixed interval. This function is provided with a choice of two parameters, Count and Filt.

Count : Measurement is started when the trigger condition has been satisfied the

specified number of times.

• Pre-trigger............... This parameter can only be set when the Function setting is Memory. It specifies

the pre-trigger period as a percentage.

CHECKPOINT

• Based on the position where the trigger condition is satisfied as the reference point, the Pretrigger function initiates data capture before or after that reference point. A Pretrigger setting of 100% equals the total capture time (the Sampling Interval setting x Block Size setting).

• The Pre-trigger time when the Capture Destination is the hard disk or PCMCIA card is calculated using the formulas below. Furthermore, the memory capacity for Pre-trigger varies according to the memory device used for the capture destination.

– Hard disk pre-trigger memory capacity: 24 MW – PCMCIA pre-trigger memory capacity : 1 kW

When there is a temperature measurement channel (when TEMP has not been selected for any channel on the AMP Settings window)

Pre-trigger memory capacity x sampling speed ÷ number of channels ÷ 2 = the pre-trigger time

When there is no temperature measurement channel (when TEMP has been selected for any channel on the AMP Settings window)

Pre-trigger memory capacity x sampling speed ÷ number of channels = the pre-trigger time

Example: Capture to hard disk, 1 µs sampling speed, 8-ch input, voltage only

24 MW x 1 µs ÷ 8 = approx. 3 s

•INT (Integration) and DINT (Double Integration) Perform the same functions as an integration amp (DC is not integrated).

• SIN (Sine) and COS (Cosine) The result of a SIN or COS operation is displayed within the range of -1 and +1. The angle is calculated in the counter-clockwise direction for positive values or the clockwise direction for negative values.

• ASIN (Arc Sine), ACOS (Arc Cosine), and ATAN (Arc Tangent) If the absolute value of the target data of an ASIN or ACOS operation is 1 or more, any value equal to +1 or higher is processed as +1 and any value equal to -1 or lower is processed as -1. For ASIN, ACOS, and ATAN operations, the calculated result is displayed as an angle (RAD) ranging from –π/2 to +π/2.

• INTA (Integration) and DINTA (Double Integration) Integration and double integration operations use a trapezoidal formula. With a trapezoidal formula, the average of the target point and its previous point is multiplied by Delta t to obtain the area, after which all the data preceding the target point are added.

• Regarding the permissible numeric range If a calculation results in a numeric value (absolute value) that is lower than

1.17 x 10-38 or higher than 1.7 x 1038, an underflow or overflow state will occur and that value will be rounded off to the closest limit value or to zero.

FFT Mode Setting Windows

All menus other than the Record Settings window and Readout Menu window shown below are the same as those in Recorder mode, except for the following restrictions. For details of common menus, please refer to Chapter 3, "Recorder Mode Settings".

Usage Methods

Usage method 1 : In FFT mode, data is captured in the internal memory when measurement starts, and is displayed using the analysis method set.

Usage method 2 : After capturing data in Recorder mode, switch to FFT mode using the MODE key and press the REPLAY key to display the data using the analysis method set.

Usage method 3 : After data capture has been completed in Recorder mode, FFT calculation can be performed by selecting FFT calculation in the Readout menu. Only in this case is it possible to return to Recorder mode.

Restrictions

• Span cannot be set.

• Annotation printing is not possible.

• The data Capture Destination can be specified as internal memory only.

• Arithmetical and statistical calculation are not possible.

• Replay CH selection and Output Ratio selection cannot be performed during data replay.

• The Format Settings window cannot be displayed.

• The trigger stop conditions cannot be used.

CAUTION

FFT calculation results cannot be printed out on chart paper. Press the COPY key to make a copy of the display screen. Note that the amplifiers do not include an anti-aliasing function, and so aliasing phenomena may occur when data measured in Recorder mode is subjected to FFT processing.

(1) Frequency................. This parameter sets the analysis frequency, in the range 0.08 Hz to 400 kHz

(depends on the amps installed).

(2) Counts ...................... This parameter specifies the number of analysis points captured during

measurement. It can be specified as either 1000 points or 2000 points.

(3) Window..................... This parameter specifies the window, which can be specified as Hanning or

Rectangular.

TIP

•The Window Parameter Under normal conditions, signal input that can be subjected to FFT analysis will continue infinitely. Out of such infinitely continuous input signals, the Window parameter lets you conduct FFT analysis of the signal input only during a limited time interval, which is called a "window." In the WR300's FFT mode, the Window length and the Frequency setting are related as follows.

Window length = x Counts setting [seconds]

(The Counts setting in the WR300's FFT mode can be either 1000 or 2000.)

• The Impact of the Window on Analyzed Results It is common knowledge that the result of FFT analysis on signal input that has been extracted by a window will match the result of a Fast Fourier Transformation operation on infinitely repeated signal input of the window length. As a result, except in cases when the window length is equal to an integral multiple of the signal input's cycle, ordinary signal input may generate a non-continuous segment due to extraction by the window. Since this non-continuous segment did not exist in the original signal input, if FFT analysis is executed in this status, the non-continuous segment will affect the result of FFT analysis. Due to the WR300's operating principles, it is not possible to eliminate the error caused by the window, but you can minimize the error by using an appropriate window.

Frequency setting [Hz]

0.4

4-4

Rectangular Window:

No operation is performed for the signal input extracted by the window. When using ordinary continuous waveforms, use of a window to extract a specific range of signal input will cause an error. With this Rectangular Window, however, you can obtain results that are not adversely affected by the window in the case of transient waveforms that attenuate inside the window or of signal input with a window length that is an integral multiple of the signal input's cycle.

Hanning Window:

To prevent the generation of non-consecutive points due to the use of a window to extract a specific range of signal input, the Hanning window gradually decreases the signal input to become zero at the starting and end points of the window. Because the signal input becomes zero at both ends of the window, you can minimize the adverse impact of using a window to extract a specific range of signal input, even when you have extracted a continuous waveform.

TIP

Description of the Function settings The time-axis data "x(i), where i = 0, 1, ... N-1)" is subjected to a Fast Fourier Transformation and its result is represented as:

X(i) = XR(i) + jXl(i), Where: i = 0, 1...N-1, j = an imaginary unit An FFT analysis of time-axis data, which consists of real numbers, results in multiple

elements containing information that indicates the amplitude and phase.

•Y-T The X axis is fixed to time and the Y axis is fixed to LIN. Just as in Recorder mode, you can detect changes in the signal input with respect to the time axis.

•Linear (Linear Spectrum) Based on the result of FFT analysis of time-axis data, either the amplitude or phase is displayed.

•P.S.D. (Power Spectrum Density) The "Power Spectrum Density" refers to the power spectrum per unit frequency. The result of FFT analysis is an integral value of the power spectrum that is distributed along a bandwidth (the width of the frequency resolution) that is determined by the selected frequency for FFT analysis (the Frequency setting) and the selected number of points to be analyzed (the Counts setting). When the signals of a power spectrum form a continuous spectrum, therefore, the resulting value varies with the currently selected Frequency and Counts settings. In the case of signals of a spectrum that is distributed along a wide bandwidth, using a Function setting of P.S.D. will allow you to obtain measured values that are unrelated to the Frequency and Counts settings.

• Cross (Cross Spectrum) This cross spectrum is the product of the spectrum of two signals for a specific frequency component. It indicates the correlation and relative power of both signals. When the Function setting is Cross, the cross spectrum of the signal input and signal output is measured and averaged. Compared with only measuring the power spectrum of the signal output, therefore, you can substantially lower the impact of noise, even for a system in which noise mixes into the signal input.

• T.R.F. (Transfer Function) This function expresses the frequency characteristics of the input and output of a transfer system. It can be used to obtain the ratio of the signal input's power spectrum to the cross spectrum of the signal input and signal output. Similar to the Cross Spectrum setting, the T.R.F. setting conducts averaging to reduce the impact of noise mixing into the system's signal input. Because the transfer function is measured throughout the entire range of the FFT analysis frequency specified by the Frequency setting, however, you must input signals that will contain the frequency components of the entire bandwidth of the FFT analysis frequency.

setting shown in the preceding table.

– In the WR300's FFT mode, the CH.A and CH.B parameters correspond to X(i)

and Y(i), respectively.

• Coherence (Coherence function) The Coherence function is obtained by calculating the ratio of [the product of the input and output power spectra] to the [the amplitude squared of the cross spectrum of the signal input and signal output]. The result expresses the causal relationship between the system's input and output signals. The value of the coherence function ranges from 0 to 1. "1" indicates that all signal output derives its power from the signal input, and "0" indicates that the power of the signal output is totally unrelated to the signal input. By measuring the coherence function, you can check the reliability of measuring the T.R.F. or other functions. When averaging is not performed, all values of the coherence function will become 1. When using the coherence function, be sure to also perform averaging.

CH.A/B ........................... This parameter specifies the channels for each analysis method.

TIP

Aliasing may cause the input frequency to differ from the analyzed result. < Aliasing > Because the WR300 conducts measurement by using an analog-to-digital converter to sample signals, if the frequency of the signal input becomes greater than 50% of the frequency of the sampling interval, a phenomenon occurs in which theWR300 inadvertently measures a frequency that has not been input. This phenomenon is called "aliasing".

X/Y ................................. This parameter sets the X and Y axis scales. The scales that can be selected vary

according to the current Function setting. When the Function setting is Y-T, the settings are fixed to:

X axis: Time; Y axis: LIN.

When the Function setting is Linear, Power, P.S.D., Cross, or Transfer:

X axis: LIN. or LOG.; Y axis: LIN., LOG., or Phase

When the Function setting is Coherence, the settings are fixed to:

X axis: LIN; Y axis: LIN.

RMS ............................... The RMS parameter only requires setting when a zone's Function parameter is

Linear, Power, P.S.D., or Cross. RMS can be specified as On or Off.

CHECKPOINT

When RMS is specified as On, the Y axis is displayed as an RMS scale.

CH. A Calc., CH. B Calc.

has been set as Linear, Power, P.S.D., Cross, Transfer, or Coherence. Calculation can be specified as Off, DIF., DDIF., INT., or DINT.
