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 power supply voltage matches the rated supply voltage of the DL850E/DL850EV 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 three-prong type power cord. Connect the power cord to a properly grounded three-prong 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 may result in electric shock or damage to the instrument.

Do Not Use When the Protection Functions Are Defective

Before using this instrument, check that the protection functions, such as the protective grounding and fuse, are working properly. If you suspect a defect, do not use the instrument.

Do Not Operate in an Explosive Atmosphere

Do not operate the instrument in the presence of flammable gasses or vapors. Doing so is extremely dangerous.

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. Before touching a circuit, turn off its power and check that it has no voltage.

xiv

Precautions to Be Taken When Using the DC Power Supply (When using a DL850EV DC power supply model)

• Make sure to perform protective earth grounding to prevent electric shock.

• Connect the DC power cord after checking that the power switch of the instrument is turned OFF. If you connect the power cord with the power switch turned ON, sparks may be emitted and can lead to fire.

IM DL850E-03EN

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 DL850E/DL850EV.

• 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.

• Avoid continuous connection under an environment in which the surge voltage may occur.

Precautions to Be Taken When Using the Probes

• To measure high voltage with the 701250 (HS10M12), 701251 (HS1M16), 720210 (HS100M12), 720211 (HS100M12), or 720254 (4CH 1M16), use the isolated probes (700929, 701947), passive probes 702902, 1:1 safety cables (combination of 701901 and 701954), or differential probes (700924, 700925, 701926).

• Be sure to connect the ground lead of the differential probe (700924, 700925, 701926) to the functional grounding terminal on the right side panel of the DL850E/DL850EV before connecting to the measurement target. Not doing so may cause high voltage to appear in the BNC connector of the differential probe.

• 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. Also, when you measure high voltages above 42 V, be sure to use the passive probe 701940.

• The BNC portion of the passive probe 701940 is metal, so if you use it with isolated input (the 701250 (HS10M12), 701251 (HS1M16), etc.), for safety, be sure to only use it with voltages at or below 42 V.(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 you apply high voltages to the 701267 (HV (with RMS)), use a measurement lead 758933 and alligator clip 701954.

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

CAUTION

IM DL850E-03EN

Safety Precautions

Précautions à prendre lors de l’utilisation des modules

• Ne pas dépasser les valeurs maximales de tension d’entrée, de tension de maintien ou de surtension admissible.

• Pour éviter tout risque de choc électrique, toujours relier le DL850E/DL850EV à la terre.

• Pour éviter tout risque de choc électrique, toujours serrer les vis des modules, à défaut de quoi les fonctions de protection électrique et de protection mécanique ne seront pas activées.

• Éviter les connexions continues dans les environnements pouvant être soumis à surtension.

Précautions à prendre lors de l’utilisation de sondes

• Lors de la mesure de tensions élevées à l’aide du 701250 (HS10M12), 701251 (HS1M16), 720210 (HS100M12), 720211 (HS100M12) ou 720254 (4CH 1M16), utiliser une sonde isolée (700929 ou 701947), un câble de sécurité 1:1 (701901 et 701954 conjointement) ou une sonde différentielle (700924, 700925 ou 701926).

• Bien relier le fil de terre de la sonde différentielle (700924, 700925, 701926) à la borne de mise à la terre opérationnelle, sur le panneau droit de DL850E/DL850EV avant de le relier à la cible de la mesure. Le fait de ne pas respecter cette consigne risque d’entraîner l’apparition d’une tension élevée au niveau du connecteur BNC de la sonde différentielle.

• Lors de l’utilisation du 701255 (NONISO_10M12), veillez à serrer les vis du module. Le serrage des vis de module active la fonction de protection et celle de non-isolation. La situation est extrêmement dangereuse lorsque les vis ne sont pas serrées. Lorsque vous mesurez des hautes tensions supérieures à 42 V, veillez également à utiliser la sonde passive 701940.

• La partie BNC de la sonde passive 701940 est en métal ; si vous l’utilisez avec l’entrée isolée (la 701250 (HS10M12), 701251 (HS1M16), etc.), veillez à l’utiliser uniquement à des tensions inférieures ou égales à 42 V pour des raisons de sécurité (ne reliez pas une tension supérieure à 42 V sur les côtés Haut et Bas).

Pour les entrées non isolées (701255 (NONISO_10M12), etc.), serrez les vis du module

comme décrit ci-dessus.

• Lorsque vous appliquez de hautes tensions au 701267 (HV (avec RMS)), utilisez un cordon de mesure 758933 et une pince crocodile 701954.

• La catégorie de mesure du 701267 (HV (avec RMS)) est 400 V-CAT II dans la partie basse et 700V-CAT II dans la partie haute. Faites attention car la tolérance de surtension diffère entre les côtés bas et haut.

ATTENTION

Measured values

Physical values

2.1 Vertical and Horizontal Axes

Vertical Scale

The vertical scale is used to adjust the displayed waveform amplitude so that you can easily view signals. You can set the vertical scale to determine the value per grid square (1 div) displayed on the screen and to set the measurement range. Use the SCALE knob to set the vertical scale for each channel.

Vertical Position

Because the DL850E/DL850EV can display many waveforms, the waveforms may overlap and be difficult to view. If this happens, you can adjust the vertical display position to make waveforms easier to view (vertical position). Use the POSITION knob to set the vertical position for each channel.

Input Coupling

You can change the input coupling setting to match the signal that you are measuring. By changing the setting, you can choose how the vertical-axis (voltage-axis) control circuit is coupled to the input signal. The following types of input coupling are available: DC, AC, GND, TC, DC-RMS, AC-RMS, ACCEL, and OFF.

Set the appropriate input coupling for each input module.

* You can only select OFF for sub channels on the 16-CH voltage input module or the 16-CH temperature/

voltage input module. Sub channels set to OFF are not measured.

Vertical Zoom

You can zoom the waveform vertically. You can zoom the waveform by setting the vertical magnification or by setting upper and lower display limits.

Linear Scaling

Linear scaling is a function that converts measured values into physical values and reads them directly. There two types of linear scaling:

AX + B

Using scaling coefficient A and offset B, the DL850E/DL850EV scales values according to the

equation below.

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

P1-P2

The DL850E/DL850EV determines the scale conversion equation (y = ax + b) using four values that

you specify: two measured values (P1:X, P2:X) and the value that each one should be converted to (P1:Y, P2:Y).

The DL850E/DL850EV scales values using the scale conversion equation that it determines.

2.1 Vertical and Horizontal Axes

Horizontal Axis (Time Axis)

Time Axis Setting

Normally, under the initial settings, the time axis scale is set as a length of time per grid division (1 div). The selectable range is 100 ns/div to 20 days/div. As you adjust the value, the unit changes between seconds, minutes, hours, and days automatically. Because the horizontal display range is 10 div, the amount of time on the waveform that is displayed is equal to the time axis setting × 10. * If a 720210 (HS100M12) or 720211 (HS100M12) module is installed, the lowest setting is 100 ns/div.

Otherwise, it is 1 μs/div.

Internal and External Clocks (Time base selection)

Under the initial settings, the DL850E/DL850EV samples the measured signal using the internal clock signal produced by its internal time-base circuit. You can also use an external clock signal to control sampling. Apply the external clock signal to the external clock input terminal. This external clock input is useful for synchronizing to the clock signal of the waveform that is being measured.

Relationship between the Time Axis Setting, Record Length, and Sample Rate

If you change the time axis setting, the sample rate and the acquisition-memory record length also change. For details, see appendix 1.

Main Features

Sample Rate

If you change the time axis setting, the sample rate also changes. The sample rate is the number

of samples-per-second (S/s). When the sample rate is low compared to the frequency of the input signal, the high-frequency components of the waveform are misread as low-frequency components. To prevent the high-frequency components from being misread, sample the signal at the highest sample rate possible, or set the waveform acquisition mode to Envelope.

Roll Mode Display

When the trigger mode is Auto, Auto Level, Single, or On Start and the time axis setting is 100 ms/div

or longer, instead of updating waveforms through triggering (update mode), the DL850E/DL850EV displays the waveforms in roll mode. In roll mode, waveforms scroll from right to left as new data is captured and the oldest values are deleted from the screen.

Trigger

passes

A trigger is a cue used to display the waveform on the screen. A trigger occurs when the specified trigger condition is met, and a waveform is displayed on the screen.

Trigger Modes

The trigger mode determines the conditions for updating the displayed waveforms. There are six trigger modes: Auto, Auto Level, Normal, Single, N Single, and On Start. The trigger mode setting applies to all trigger types.

Trigger Types

Triggers can be broadly divided into “simple triggers” and “enhanced triggers.”

Simple Triggers

Input Signal Trigger

The DL850E/DL850EV triggers when the trigger source passes through the specified trigger level in

the specified way (rising edge, falling edge, or rising or falling edge).

Time Trigger

The DL850E/DL850EV triggers at the specified date and time and at specified intervals afterwards.

External Signal Trigger

The DL850E/DL850EV triggers when the signal applied to the TRIG IN terminal passes through the

specified trigger level in the specified way (rising or falling edge).

Power Line Signal Trigger

The DL850E/DL850EV triggers on the rising edge of the power supply signal that it is receiving.

This trigger enables you to observe waveforms in synchronization with the power supply frequency.

Enhanced Triggers

A -> B(N) Trigger

After state condition A is met, the DL850E/DL850EV triggers when state condition B is met N times.

A Delay B Trigger

After state condition A is met and the specified amount of time elapses, the DL850E/DL850EV

triggers when state condition B is first met.

AND Trigger

The DL850E/DL850EV triggers on the AND of multiple trigger source conditions. The DL850E/

DL850EV triggers when all the specified conditions are met at a single point.

Period Trigger

The DL850E/DL850EV triggers on a specified period of occurrence of state condition B. The

DL850E/DL850EV triggers when state condition B occurs again.

Pulse Width Trigger

The DL850E/DL850EV triggers according to the relationship between the state condition B

achievement time and the specified reference times (Time or T1 and T2).

Main Features

Wave Window Trigger

The DL850E/DL850EV creates real-time templates (Wave Window) using a number of cycles

directly preceding the current waveforms. The DL850E/DL850EV compares the current waveforms to the real-time templates and triggers if one of the current waveforms falls outside of its real-time template.

2.2 Triggering

Trigger Source

Trigger Level

Trigger Slope

Trigger Hysteresis

Trigger source refers to the signal that is used to check the specified trigger conditions. You can set the trigger source to an analog signal, logic signal, realtime math signal, time, external signal, or power line signal. Select the appropriate trigger source for the trigger type.

Trigger level refers to the signal level used as a reference for detecting a signal’s rising and falling edges or high and low states. With simple triggers such as the edge trigger, the DL850E/DL850EV triggers when the trigger source level passes through the specified trigger level. The range and resolutions that you can use to set the trigger level vary depending on the type of signal being measured.

Slope refers to the movement of the signal from a low level to a high level (rising edge) or from a high level to a low level (falling edge). When a slope is used as one of the trigger conditions, it is called a trigger slope.

When the trigger source is an analog signal, you can set a width (hysteresis) to the trigger level so that the DL850E/DL850EV does not detect edges when the signal level changes within the specified width. You can set the hysteresis around the trigger level for each type of measured signal.

Trigger Hold-off

The trigger hold-off feature temporarily stops the detection of the next trigger once a trigger has occurred. This feature is useful in cases when you want to change the waveform acquisition interval, such as when you are observing a PCM (pulse code modulation) code or other pulse train signal or when you are using the history feature.

Trigger Position

When you move the trigger position, the ratio of the displayed data before the trigger point (pre-data) to the data after the trigger point (post-data) changes. When the trigger delay is 0 s, the trigger point and trigger positions coincide.

Trigger Delay

The DL850E/DL850EV normally displays waveforms before and after the trigger point. You can set a trigger delay to display waveforms at a specified amount of time after the trigger occurrence.

2.3 Waveform Acquisition

Based on the data that has been stored in the acquisition memory, the DL850E/DL850EV performs various operations, such as displaying waveforms on the screen, computing, measuring cursors, and automatically measuring waveform parameters. You can set the number of data points to store in the acquisition memory (the record length), enable or disable the sample data averaging feature, and so on.

Record Length

Record length refers to the number of data points that are stored to the acquisition memory for each channel. Display record length refers to the data points from the data stored in the acquisition memory that are displayed on the screen. Normally, the acquisition-memory record length and display record length are the same, but the time axis setting may cause them to differ. When you change the time axis setting, the sample rate and record length also change. On the standard model of the DL850E/DL850EV, you can set the record length to a value between 1 kpoint and 250 Mpoint. Depending on the model, you can set the record length to a value of up to 2 Gpoint.

Acquisition Mode

Specify how the DL850E/DL850EV processes the sampled data, stores it in the acquisition memory, and uses it to display waveforms. There are four acquisition modes: Normal, Envelope, Averaging, and BoxAverage.

When waveforms are being measured, the waveform data stored in the acquisition memory as a result of a trigger occurrence is displayed as a waveform on the DL850E/DL850EV screen and can be viewed. When waveform acquisition is being triggered in succession and an abnormal waveform appears, it is impossible to stop acquisition before a new waveform appears on the screen. Normally, it would be impossible to view the abnormal waveform. However, with the history feature, you can view the past waveform data (history waveforms) stored in the acquisition memory when waveform acquisition is stopped. You can select specific history waveforms and display them. You can also search through the history waveforms for waveforms that meet specified conditions.

• Zone Search The DL850E/DL850EV searches for history waveforms that passed (or did not pass) through a

specified search zone.

• Waveform Parameter Search The DL850E/DL850EV searches for waveforms whose measured waveform parameter values meet

(or do not meet) specified conditions.

Updated waveform

The DL850E/DL850EV has a main window for displaying normal time-domain waveforms, zoom windows for displaying zoomed time-axis waveforms, and X-Y windows for displaying X-Y waveforms. In addition, you can split screens and change the sizes of waveform display areas so that waveforms and measured values are easier to see and display an FFT window that shows the results of FFT analysis.

Zooming along the Time Axis (GIGAZoom)

You can magnify displayed waveforms along the time axis. The zoomed waveforms of two locations can be displayed simultaneously (the dual zoom feature). This feature is useful when you set a long acquisition time and want to observe a portion of the waveform closely.

Zoom box 1

Displaying X-Y Waveforms

You can observe the correlation between two waveform signal levels by displaying one signal level on the X-axis (horizontal axis) and a second signal level on the Y-axis (vertical axis). You can display X-Y waveforms at the same time as normal T-Y (time and signal level) waveforms. You can display up to four overlapping X-Y waveforms in both Window1 and Window2. Because multiple X-Y waveforms can be displayed, it is easy to compare the relationships between phases. You can use this feature to evaluate DC motors using Lissajous waveforms.

Snapshot

You can continue displaying a waveform on the screen as a snapshot waveform after the screen has been updated and the waveform has been cleared in update mode or after the waveform has left the screen in roll mode. Snapshot waveforms appear in white. You can compare them with new waveforms. You can also save and print snapshot waveforms as screen captures.

Waveform Computation

You can perform basic arithmetic, binarization, FFT (power spectrum), and phase shifting (display the waveform with its phase shifted). On models with the /G2 option, you can use a rich variety of functions (square root, trigonometric functions, differentiation, integration, digital filtering, six types of FFT functions, and so on) to define up to eight equations.

Cursor Measurement

There are cursors for T-Y (time-axis), X-Y, and FFT waveforms. You can position a cursor over a waveform to view the various measured values at the intersection of the cursor and the waveform.

Automated Measurement of Waveform Parameters

You can use this feature to automatically measure waveform levels, maximum values, frequencies, and other values. For waveform data, you can measure 29 waveform parameters (including the delay between channels) that relate to the voltage axis, time axis, and waveform area.

• You can display a total of 32 measured values for all the waveforms.

• You can save a total of 64000 items of data for all the waveforms.

• You can also perform computations on measured waveform parameter values.

• You can display the following statistics for the specified waveform parameter. The maximum value (Maximum), minimum value (Minimum), average value (Average), standard

2.5 Waveform Computation and Analysis

There are three statistical processing methods:

• Normal statistical processing While acquiring waveforms, the DL850E/DL850EV measures the measurement items and

calculates the statistics of the waveforms that it has acquired so far.

• Cyclic statistical processing (measurement and statistical processing are performed for each period) The DL850E/DL850EV divides the waveform into periods starting at the left side of the screen (the

oldest waveform) and moving to the right side of the screen, measures the selected measurement items within each period, and performs statistical processing on the measurement items.

• Statistical processing of history waveforms The DL850E/DL850EV measures the measurement items and calculates the statistics of history

waveforms. Measurement and statistical processing begin with the oldest waveform.

GO/NO-GO Determination

This feature is useful for signal testing on production lines and for tracking down abnormal phenomena. The DL850E/DL850EV determines whether the waveform enters the specified range. When the DL850E/DL850EV returns a GO (or NO-GO) result, specified actions are performed.

Determination Methods

• Waveform Zone The DL850E/DL850EV returns GO/NO-GO results based on whether waveforms leave or enter

the zone that you create using a base waveform.

• Waveform Parameter Set the upper and lower limits for automated measurement values of waveform parameters. The

Actions Performed according to Determination Results

The DL850E/DL850EV can print and save screen captures, save waveform data, beep, and send

e-mails according to the results of GO/NO-GO determination.

The DL850E/DL850EV returns a GO or NO-GO judgment according to the determination condition.

3.3 Installing Input Modules

WARNING

• To prevent electric shock and damage to the instrument, be sure to turn the power off before you install or remove input modules.

• Check that the input cable is not connected to the input terminals before installing or removing the input module.

• To prevent electric shock and to satisfy the specifications, make sure to put the accessory cover panel on the slots that are not being used.

Using the instrument without the cover panel allows the dust to enter the instrument and

may cause malfunction due to the rise in temperature inside the instrument.

• If the input module happens to come out of the slot while it is in use, it may cause electric shock or cause damage to the instrument as well as the input module. Make sure to screw the input module in place at the two locations (top and bottom).

• There are protrusions in the slot. Do not put your hand in the slot. If you put your hand in the slot, the protrusions may cut your hand.

• Use the accessories of this product within the rated range of each accessory (see page ix). When using several accessories together, use them within the specification range of the accessory with the lowest rating.

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 avoid electric shock, be sure to ground the instrument.

• To prevent the possibility of electric shock, be sure to fasten the module screws. Failing to do so is extremely dangerous, because the electrical and mechanical protection functions will not be activated.

• Avoid continuous connection under an environment in which the surge voltage may occur.

• To measure high voltage with the 720210 (HS100M12), 720211 (HS100M12), 701250 (HS10M12), 701251 (HS1M16), or 720254 (4CH 1M16), use the isolated probes (700929,

701947), passive probes 702902, 1:1 safety cables (combination of 701901 and 701954), or differential probes (700924, 700925, 701926).

• Be sure to connect the GND lead of the differential probe (the 700924, 700925 and

701926) to the functional ground terminal of the DL850E/DL850EV before you connect to the device under measurement. High voltage may appear at the BNC connector of the differential probe.

• The protection functions and non-isolation functions of the 701255 (NONISO_10M12) are enabled when the module screws are tightened. It is extremely dangerous if you do not fasten the screws. Also, when you measure high voltages above 42 V, be sure to use the passive probe for the DL850E/DL850EV (the 701940).

• The BNC portion of the 10 MHz passive probe 701940 is metal, so if you use it with isolated input (the 720210 (HS100M12), 720211 (HS100M12), 701250 (HS10M12), 701251 (HS1M16), 701275 (ACCL/VOLT), 701281(FREQ)), or 720254 (4CH 1M16), for safety, be sure to only use it with voltages at or below 42 V. (Do not connect voltage above 42 V to both the High and Low sides.)

• When measuring high voltages using the 701267 (HV (with RMS)), use a measurement lead 758933 and alligator clip 701954.

• The measurement category of 701267 (HV (with RMS)) when used with 758933 measurement leads and 701954 alligator clips is 400V-CAT II on the low side and 700V-CAT II on the high side. Be careful because the overvoltage tolerance between the low and high sides is different.

• To measure high voltage with the 701281 (FREQ), use an isolated probe (700929, 701947) or passive probe 702902.

• The protection functions and non-isolation functions of the 720230 (LOGIC) are enabled when the module screws are tightened. It is extremely dangerous if you do not fasten the screws. Also, be sure to only use a recommended YOKOGAWA logic probe (700986, 700987, 702911, or 702912) with the logic module.

CAUTION

Abruptly turning off the power switch or unplugging the power cord while data is being saved or the internal printer is printing may corrupt the media on which data is being saved or damage the built-in printer. Also, the data being saved is not guaranteed. Always turn the power switch off after data has been saved.

French

ATTENTION

Mettre brutalement l’instrument hors tension ou débrancher le cordon d’alimentation pendant l’enregistrement de données ou le fonctionnement de l’imprimante interne peut corrompre le support d’enregistrement des données ou endommager l’imprimante intégrée. Les données en cours d’enregistrement pourront également être perdues. Toujours mettre l’instrument hors tension après que les données ont été enregistrées.

Operations Performed When the Power Is Turned On

When the power switch is turned on, self testing and calibration start automatically. This lasts for approximately 30 seconds. When the DL850E/DL850EV starts normally, the waveform display screen appears. Check that the DL850E/DL850EV has started normally before you use it.

If the DL850E/DL850EV Does Not Start Normally When the Power Is Turned On

Turn off the power switch, and check the following items.

• Check that the power cord is securely connected.

• Check that the correct voltage is coming to the power outlet. → See page 3-12

• Initialize the settings to their factory defaults by turning on the power switch while holding down the RESET key. For details about initializing the settings, see section 4.6, “Initializing Settings.”

If the instrument still does not work properly, contact your nearest YOKOGAWA dealer for repairs.

Note

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

• On the DC power supply option, repeatedly turning the power switch on and off will stop the power from

being supplied because the internal protection will be activated. If you refrain from turning the power on or off for 10 to 20 seconds, the internal protection will be released, and power supply will be restored. The DC power supply LED lights in orange while power is not being supplied.

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

Operations Performed When the Power Is Turned Off

When the power switch is turned off (or the power plug is removed), the instrument stores the current settings in its memory. This means that if you turn the power switch on and begin measurement, the instrument will perform measurements using the settings from immediately before the instrument was last turned off.

Note

The instrument stores the settings using an internal lithium battery. The battery lasts for approximately five years when the ambient temperature is 23°C. When the lithium battery voltage falls below a specified value and you turn on the power, a message (error 901) appears on the screen. If this message appears frequently, you need to replace the battery soon. Do not try to replace the battery yourself. Contact your nearest YOKOGAWA dealer to have the battery replaced.

3-16

To Make Accurate Measurements

• After turning on the power switch, wait at least 30 minutes to allow the instrument to warm up.

• Perform calibration after the instrument has warmed up (see section 4.7 for details). If auto calibration is turned on, auto calibration is executed when you change the Time/div setting or start waveform acquisition.

Making Preparations for Measurements

WARNING

When connecting a device under measurement to the instrument, be sure to turn off the device. It is extremely dangerous to connect or remove measurement leads while the device under measurement is on.

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 avoid electric shock, be sure to ground the instrument.

• 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.

• Avoid continuous connection under an environment in which the surge voltage may occur.

• Use only specified cables. It is extremely dangerous to use cables that do not meet the safety standards. (Especially when you are handling high voltages of 42 V or more.)

• To measure high voltage with the 720210 (HS100M12), 720211 (HS100M12), 701250 (HS10M12), 701251 (HS1M16), or 720254 (4CH 1M16), use the isolated probes (700929,

701947), passive probes 702902, 1:1 safety cables (combination of 701901 and 701954), or differential probes (700924, 700925, 701926).

• The BNC portion of the 10 MHz passive probe (701940) is metal, so if you use it with isolated input (the 720210 (HS100M12), 720211 (HS100M12), 701250 (HS10M12), 701251 (HS1M16), 701275 (ACCL/VOLT), 701281(FREQ)), or 720254 (4CH 1M16), for safety, be sure to only use it with voltages at or below 42 V. (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.

• To measure high voltage with the 701281 (FREQ), use an isolated probe (700929, 701947) or passive probe 702902.

3.5 Connecting Probes

Précautions à prendre lors de l’utilisation des modules

• Ne pas dépasser les valeurs maximales de tension d’entrée, de tension de maintien ou de surtension admissible.

• Pour éviter tout risque de choc électrique, l’instrument doit impérativement être relié à la terre.

• Pour éviter tout risque de choc électrique, toujours serrer les vis des modules, à défaut de quoi les fonctions de protection électrique et de protection mécanique ne seront pas activées.

• Éviter les connexions continues dans les environnements pouvant être soumis à surtension.

• Utilisez uniquement les câbles préconisés. Il est extrêmement dangereux d’utiliser des câbles n’étant pas conformes aux normes de sécurité. (notamment lorsque vous travaillez avec de hautes tensions de 42 V, voire supérieures).

• Pour mesurer la tension élevée avec 720210 (HS100M12), 720211 (HS100M12), 701250 (HS10M12), 701251 (HS1M16) ou 720254 (4CH 1M16), utiliser des sondes isolées (700929,

701947), des sondes passives 702902, des câbles de sécurité 1:1 (combinaison de 701901 et 701954) ou des sondes différentielles (700924, 700925, 701926).

• La partie BNC de la sonde passive de 10 MHz 701940 est en métal ; si vous l’utilisez avec l’entrée isolée (720210 (HS100M12), 720211 (HS100M12), 701250 (HS10M12), 701251 (HS1M16), 701275 (ACCL/VOLT), 701281(FREQ) ou 720254 (4CH 1M16)), veillez à l’utiliser uniquement avec des tensions inférieures ou égales à 42 V pour des raisons de sécurité (ne reliez pas une tension supérieure à 42 V aux côtés Haut et Bas). Pour les entrées non isolées (701255 (NONISO_10M12), etc.), serrez les vis du module.

• Pour mesurer la tension élevée avec 701281 (FREQ), utiliser une sonde isolée (700929,

701947) ou une sonde passive 702902.

Precautions to Be Taken When Connecting Probes

• When connecting a probe to the instrument for the first time, perform phase correction of the probe as described in section 3.6, “Compensating the Probe (Phase Correction).” Make the phase correction on each channel to which the probe is to be connected.

• You cannot perform phase correction of the probe on the frequency module (701281 (FREQ)) and SENT monitor module (720243 (SENT)). When connecting a probe to the 701281 (FREQ) or 720243 (SENT), first perform phase correction on the probe using another module.

• If the object to be measured is connected to the instrument directly, without using a probe, a correct measurement cannot be performed due to the input impedance. Please be aware of this.

• Note that if you use a voltage probe other than an isolated probe (700929 or 701947) or passive probe (702902), correct measurements cannot be displayed when the attenuation is not 1:1, 10:1, 100:1, or 1000:1.

• Follow the instructions given in section 1.1, “Configuring Voltage Measurements,” in the user’s manual to set the probe attenuation or the current-to-voltage conversion ratio to match the actual value using the setup menu. If they do not match, measured values cannot be read correctly.

3.6 Correcting the Probe Phase

Necessity of Phase Correction of the Probe

If the probe’s input capacitance is not within the appropriate range, the gain will not be steady in relation to the frequency, and waveforms will not be displayed correctly. Also, because the input capacitance is not the same for each probe, the probe’s have variable capacitors (trimmers) that need to be adjusted. This adjustment is referred to as phase correction. Always correct the phase of a probe that you are using for the first time. Also, because the appropriate input capacitance range is different for each channel, you need to perform phase correction when you change the channel that a probe is connected to.

Phase Compensation Signal

Making Preparations for Measurements

The instrument generates the following square wave signal from the COMP signal output terminal.

Notes about Using Probes with the Frequency Module or SENT Monitor Module

You cannot perform phase correction on a probe connected to the frequency module and SENT monitor module. To use a probe with the frequency module or SENT monitor module, first perform phase correction on the probe using another module.

3.9 Connecting Bridgeheads

Strain is measured by connecting a strain gauge bridge (bridge head) or a strain gauge transducer to the strain module. This section will mainly describe the procedures and precautions related to the connection of the bridge head (Model 701955, 701956, 701957, and 701958). For the connection of other strain gauge bridges or strain gauge transducers, see the respective manuals.

CAUTION

Only connect a strain gauge bridge (bridge head) or a strain gauge transducer to the strain module. Connecting other devices or applying a voltage that exceeds the values indicated below to the strain module may damage the input section.

• Maximum input voltage (between Input+ and Input–) 10 V (DC + ACpeak)

• Maximum allowable common mode voltage (between each terminal and earth ground) 42 V (DC + ACpeak) (CAT II, 30 Vrms)

French

ATTENTION

Brancher seulement un pont de jauge de contrainte (tête de pont) ou un transducteur de jauge de contrainte au module de contrainte. Le fait de brancher d’autres appareils ou d’appliquer une tension dépassant les valeurs indiquées ci-dessous sur le module de contrainte risque d’endommager la zone d’entrée.

• Tension d’entrée maximale (entre l’entrée + et l’entrée –) 10 V (c.c. + crête c.a.)

• Tension de mode commun autorisée maximale (entre chaque borne et mise à la terre) 42 V (c.c. + crête c.a.) (CAT II, 30 Vrms)

Connecting the Strain Gauge

The bridge head (701955, 701956, 701957, and 701958) supports six types of connection methods:

single-gauge method, single-gauge three-wire method, adjacent-side two-gauge method, oppositeside two-gauge method, opposite-side two-gauge three-wire method, and four-gauge method. For details, see the manual that came with the bridge head (701955, 701956, 701957, or 701958).

If you are using a strain gauge bridge or a strain gauge transducer other than the bridge head

(701955, 701956, 701957, and 701958), see the respective manuals.

3.10 Connecting a Logic Probe to the Logic Input

Module

To measure logic signals, connect a logic probe (the 702911, 702912, 700986, or 700987) to a logic input module (the 720230).

CAUTION

• Applying a voltage greater than the limits listed below may damage the logic probe or the instrument. For frequencies above 1 kHz, damage may occur even if the voltage is less than the limits listed below.

Maximum input voltage (at a frequency of 1 kHz or less)

• Logic probes (702911 and 702912): 35 V

• High-speed logic probe 700986: 42 V (DC + ACpeak)

• Isolated logic probe 700987: 250 Vrms (however, ACpeak must be less than 350 V,

and DC must be less than 250 V)

• For logic probes (702911 and 702912), and high-speed logic probe 700986, the eight input lines of a single pod share the same ground. Also, the instrument’s ground and the grounds of each pod are connected. Do not apply signals with different common voltages to each input line. Doing so may damage the instrument, connected logic probes, and connected devices.

• The input terminals of an isolated logic probe are isolated from each other and from the DL850E/DL850EV.

• Turn off the DL850E/DL850EV before you connect or remove a 26-pin connector from the logic signal input connector.

• Do not stack the isolated logic probes during use. Also, allow enough space around the probes to avoid a temperature increase inside the probes.

• Do not use the YOKOGAWA 700985 logic probe with the DL850E/DL850EV. The 700985 is shaped so that it can be connected to the logic signal input connector of the DL850E/ DL850EV, but it is not electrically compatible with the DL850E/DL850EV, so connecting the two could damage the DL850E/DL850EV or the 700985.

• Sondes logiques 702911 et 702912 : 35 V

• Sonde logique à grande vitesse 700986 : 42 V (c.c. + crête c.a.)

• Sonde logique isolée 700987 : 250 Vrms (cependant, la valeur crête c.a. doit

• Pour les sondes logiques 702911, 702912 et la sonde logique à grande vitesse 700986, les huit lignes d’entrée d’une cosse unique partagent la même terre. De plus, la terre de l’instrument et celles de chaque cosse sont reliées. Ne pas émettre de signaux de tensions communes différentes vers chaque ligne d’entrée. Cela risquerait d’endommager l’instrument, les sondes logiques reliées et les appareils reliés.

3.10 Connecting a Logic Probe to the Logic Input Module

• Éteindre DL850E/DL850EV avant de brancher un connecteur de 26 broches au connecteur d’entrée du signal logique ou de l’en retirer.

• Ne pas empiler les sondes logiques isolées lors de leur utilisation. Laisser également suffisamment d’espace autour des sondes pour éviter une augmentation de température à l’intérieur des sondes.

• Ne pas utiliser la sonde logique YOKOGAWA 700985 avec DL850E/DL850EV. Le dispositif 700985 est conçu pour pouvoir être branché au connecteur d’entrée de signal logique de DL850E/DL850EV, mais il n’est pas électriquement compatible au dispositif DL850E/ DL850EV. Par conséquent, le fait de brancher les deux ensemble risque d’endommager DL850E/DL850EV ou 700985.

Connecting Acceleration Sensors

When Connecting Built-in Amplifier Type Acceleration Sensors

The DL850E/DL850EV allows built-in amplifier type (low impedance) acceleration sensors to be directly connected. To connect built-in amplifier type acceleration sensors, use BNC cables. Use cables that are appropriate for the acceleration sensors being used. Connect the acceleration sensors with the bias current turned off. After connection, turn on the supply current to the acceleration sensors for making measurements.

When Connecting Charge Output Type Acceleration Sensors

Since the charge output type (high impedance) acceleration sensors do not have built-in amplifier circuit, they cannot be directly connected to the DL850E/DL850EV. Use either of the following two methods to connect the sensors.

Using the Charge Amplifier

Connect a charge-output-type acceleration sensor to the charge amplifier using a high-insulation,

low-noise cable. The acceleration signal (charge signal) that has been converted to a voltage signal by the charge amplifier is input to the DL850E/DL850EV using a normal coaxial cable. The DL850E/ DL850EV measures the signal in the voltage measurement mode. The measured data can be converted to acceleration values using the scale conversion function of the DL850E/DL850EV.

acceleration sensor

When using the charge converter

Connect a charge-output-type acceleration sensor to the charge converter using a high-insulation,

low-noise cable. By driving the charge converter using a constant current from the DL850E/DL850EV, voltage signals similar to those of the built-in amplifier type acceleration sensor can be obtained. The DL850E/DL850EV measures the signals in the acceleration measurement mode and supplies bias current to the charge converter. Set the input sensitivity of the DL850E/DL850EV according to the charge converter gain and the sensitivity of the charge output type acceleration sensor.

The DL850E/DL850EV only supports charge converters that are driven by constant current with

Precautions

• Do not apply shock outside the specifications (see the manual for the acceleration sensor) to the acceleration sensors. Doing so can damage the sensors.

• Do not impose drastic temperature changes on the acceleration sensors. Temperature changes may affect the output value of the acceleration sensors.

• By default, the bias current on the acceleration sensors is turned off. Be sure to turn it on before using the acceleration sensors. Bias current is valid only when measuring acceleration. When measuring other parameters, it is automatically turned off. The bias current on/off setting is saved when the DL850E/DL850EV is turned off.

• The DL850E/DL850EV allows power-generating electromagnetic pickup to be connected directly. The DL850E/DL850EV does not support electromagnetic pickups that require external power supply or those that require a terminator at the output.

• To connect electromagnetic pickups, use BNC cables. Use cables that are appropriate for the electromagnetic pickups being used.

• When the input is set to electromagnetic pickup, determination is not made on whether the input voltage level exceeds the specified input voltage range. Therefore, the LEDs (see page 3-10) do not illuminate eve when the input voltage level is over range.

To measure voltages with the 16-CH voltage input module (720220 (16CH VOLT)), connect wires to the terminal block.

WARNING

When connecting a device under measurement to the instrument, be sure to turn off the device.

It is extremely dangerous to connect or remove wires while the device under measurement is on.

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 avoid electric shock, be sure to ground the instrument.

• 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.

• Avoid continuous connection under an environment in which the surge voltage may occur.

• To prevent electric shock, connect wires to the terminal block that match the voltage range that you are measuring.

• Applying a voltage exceeding the value indicated below may damage the input section. If the frequency is above 1 kHz, damage may occur even when the voltage is below this value.

AVERTISSEMENT

Toujours mettre l’appareil à mesurer hors tension avant de le brancher sur l’instrument. Il est extrêmement dangereux de brancher un câble de mesure lorsque l’appareil à mesurer est sous tension.

Précautions à prendre lors de l’utilisation des modules

• Ne pas dépasser les valeurs maximales de tension d’entrée, de tension de maintien ou de surtension admissible.

• Pour éviter tout risque de choc électrique, l’instrument doit impérativement être relié à la terre.

• Pour éviter tout risque de choc électrique, toujours serrer les vis des modules, à défaut de quoi les fonctions de protection électrique et de protection mécanique ne seront pas activées.

• Éviter les connexions continues dans les environnements pouvant être soumis à surtension.

• Afin d’éviter un risque de choc électrique, raccorder les câbles au bornier qui correspondent à la plage de tensions en cours de mesure.

• L’application d’une tension supérieure à la valeur indiquée ci-dessous pourrait endommager la section d’entrée. Si la fréquence est supérieure à 1 kHz, une tension inférieure à cette valeur pourra tout de même endommager la section d’entrée.

to 1.00 mm2 recommended (solid wire or thin stranded wire). AWG

Flat-blade Screwdriver

Tip size: 0.4 mm (thickness) × 2.5 mm (width) Shape: DIN5264-A (Use a straight driver.)

Connecting Wires to the Terminal Block

First, turn off the DL850E/DL850EV. Make sure that the other end of the wire that you are connecting to the terminal block is not connected to the device under measurement, or make sure that the device under measurement that you are going to connect to is turned off.

Insert the flat-blade screwdriver into the screwdriver insertion hole right next to the wire

insertion hole.

Insert the flat-blade screwdriver into the hole firmly until the wire insertion hole will open.

Insert the wire that you prepared into the wire insertion hole.

Insert the wire until it reaches the back of the wire insertion hole.

Pull the flat-blade screwdriver out of the screwdriver insertion hole.

When you pull out the flat-blade screwdriver, hold the wire in place so that it does not come out with the screwdriver.

Pull lightly on the wire to make sure that it doesn’t come out.

After you have finished connecting the wires, turn on the DL850E/DL850EV and the device under measurement.

Note

Removing and Attaching the Terminal Block

It is normally not necessary to remove the terminal block, but it is possible to do so.

Removal

Push terminal block release levers 1 and 2 to their release positions, and pull out the terminal block.

Attachment

Push terminal block release levers 1 and 2 to their lock positions, and insert the terminal block. Push the

terminal block firmly all the way to the back. However, the terminal block will not go all the way to the back if it is upside down. Do not try to force the terminal block all the way to the back.

Voltage Input Module

If you are using the 16-CH temperature/voltage input module (720221 (16CH TEMP/VOLT)) to measure temperature and voltage, connect thermocouples or wires to the 16-channel scanner box.

WARNING

When connecting a device under measurement to the instrument, be sure to turn off the device. It is extremely dangerous to connect or disconnect thermocouples or wires while the device under measurement is on.

Precautions to Be Taken When Using the Modules

• To avoid electric shock, be sure to ground the instrument.

• 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.

Precautions to Be Taken When Using the 16-CH Scanner Box

• Do not connect or disconnect the 16-CH scanner box or the cables that are connected to it while the power is on.

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

• Avoid continuous connection under an environment in which the surge voltage may occur.

• To prevent electric shock, connect wires to the terminal block that match the voltage range that you are measuring.

• Applying a voltage exceeding the value indicated below may damage the input section. If the frequency is above 1 kHz, damage may occur even when the voltage is below this value.

Maximum input voltage (across the input terminals, + and −,

42 V (DC + ACpeak)

Maximum allowable common

mode voltage (across the input terminals, + or −, and earth,2

at a frequency of 1 kHz or less) 42 V (DC + ACpeak) (CAT II, 30 Vrms)

• The − input terminals of the sub channels are electrically insulated inside the scanner

box. If you connect a wire that has a potential difference greater than 42 V (DC + ACpeak) between sub channels, the insulation may be damaged, which will lead to the 16-CH scanner box being damaged.

3.14 Connecting Wires to the 16-CH Temperature/Voltage Input Module

CAUTION

• Correct measurements cannot be obtained when the positive and negative thermocouple leads are connected in reverse.

• Immediately after connecting the thermocouple, the heat balance may be disturbed at the input terminal section and may cause measurement errors. Therefore, wait about ten minutes before making a measurement.

• In an environment where the air from the air conditioning is directly applied to the input terminals or where there are effects from a heat source, the heat balance may be disturbed at the input terminal section and cause measurement errors.

When making measurements in this type of environment, take preventive measures such

as changing the position.

AVERTISSEMENT

Lors du raccordement d’un appareil en cours de mesure à l’instrument, s’assurer que l’appareil est éteint. Il est extrêmement dangereux de brancher ou débrancher des thermocouples ou des câbles lorsque l’appareil en cours de mesure est allumé.

Making Preparations for Measurements

Précautions à prendre lors de l’utilisation des modules

• Pour éviter tout risque de choc électrique, l’instrument doit impérativement être relié à la terre.

• Pour éviter tout risque de choc électrique, toujours serrer les vis des modules, à défaut de quoi les fonctions de protection électrique et de protection mécanique ne seront pas activées.

Précautions à prendre lors de l’utilisation de boîtier de scanner 16-CH

• Ne pas brancher ou débrancher le boîtier de scanner 16-CH ou les câbles qui y sont reliés s’ils sont sous tension.

• Ne pas dépasser les valeurs maximales de tension d’entrée, de tension de maintien ou de surtension admissible.

• Éviter les connexions continues dans les environnements pouvant être soumis à surtension.

• Afin d’éviter un risque de choc électrique, raccorder les câbles au bornier qui correspondent à la plage de tensions en cours de mesure.

Tension d’entrée maximale (via les bornes d’entrée, + et −,

à une fréquence d’1 kHz ou moins)

42 V (c.c. + crête c.a.)

Tension de mode commun autorisée maximale (via les bornes d’entrée, + ou −, et la terre,

à une fréquence d’1 kHz ou moins) 42 V (c.c. + crête c.a.) (CAT II, 30 Vrms)

• Les bornes d’entrée − des sous-voies sont électriquement isolées à l’intérieur du boîtier

de scanner. En cas de branchement d’un câble présentant une différence de potentiel supérieure à 42 V (c.c. + crête c.a.) entre les sous-voies, l’isolation risque d’être endommagée, ce qui causera des dégâts sur le boîtier de scanner 16-CH.
