Function Settings This chapter explains the various function settings that can be configured from the front panel.
Page 48: Function Settings Overview
Use auto zero adjustment to minimize the effects of offset on your measurements. When auto zero adjustment is enabled, the DME1600 samples the input signal as a raw value and then internally disconnects the input signal to measure the offset (the null offset). Then, the DME1600 subtracts the offset from the raw value to obtain the accurate measurement.
Page 49 To enable auto zero adjustment, select ON; otherwise select OFF. Press ENTER. Remote interface operation SENSe:ZERO:AUTO {OFF|ONCE|ON} The OFF and ONCE parameters have a similar effect. With OFF, a new offset measurement is not performed. However, with ONCE, an offset mea- surement is performed immediately. DME1600...
Page 50: Filter
Filter Filters are used to remove noise from measurement. The DME1600 has two types of filters: AC and digital. The AC filter is used only for AC voltage and AC current measurements and affects the measurement speed. The digital filter stabilizes measurement through averaging.
Page 51: Digital Filter
Then, the DME1600 flushes the stack and starts over with an empty stack. This means that in repeating average mode, the DME1600 produces a measured value each time the specified number of values are sampled.

Page 56: Dc Input Resistance
For low input DC voltage (100 mV, 1 V, and 10 V range) measurements, you can select a large input resistance (> 10 G) to reduce the loading effect of the DME1600 input resis- tance. For 100 V DCV and 1000 V DCV measurements and other measurement functions, the input resistance is fixed at 10 M.
Page 57: Threshold Resistance For Continuity Tests
Threshold Resistance for Continuity Tests When testing continuity, the DME1600 beeps when the measured resistance is less than the threshold value. You can set the threshold value to a value between 1  and 1000 . Setup conditions The default value is 10 . The setting is returned to its factory default value Factory default settings when the power switch is turned off.
Page 58: Threshold Range For Diode Tests
Threshold Range for Diode Tests The DME1600 measures the diode forward voltage using a 1 mA test current. The DME1600 beeps when the measured forward voltage is within the threshold range. Setup conditions Threshold voltages You can set the threshold voltages to values between 0.01 V and 1.2 V.
Page 59: Range (Auto And Manual)
Range (Auto and Manual) The DME1600 can automatically select measurement ranges (this feature cannot be used in continuity tests, diode tests, and temperature measurements). You can also select the range manually to reduce the settling time. When the input signal exceeds the measurable range, an OVLD message appears on the display.

Press ENTER to enter the GPIB address. Switching between Input Terminals The DME1600 has input terminals on both the front and rear panels. When you select the rear-panel input terminals, the REAR indicator in the top area of the panel display lights.
Page 69: Triggering
Triggering The DME1600 has a variety of trigger features. For each measurement function, you can set the trigger mode, trigger source, and trigger settings.  Trigger mode You can set the trigger mode to auto, immediate, or single.  Trigger source You can set the trigger source to front panel, external trigger input, or remote interface.
Page 70: Trigger Mode
Trigger Mode On the DME1600, you can set the trigger mode to auto, immediate, or single. Auto trigger mode (front panel operation only) In auto trigger mode, the DME1600 continuously takes samples at the fastest rate possible (the rate depends on the current settings).
Page 71: Single Trigger Mode (Front Panel Operation Only)
In single trigger mode, the DME1600 takes a single measurement (or the specified number of measurements) each time you press SINGLE. When the TRIG indicator is lit on the display, the DME1600 is ready for the next trigger event. Single trigger mode can only used during front panel operation.

Page 73: External Trigger Input
External trigger input You can use external trigger pulses applied to the rear-panel EXT TRIG (BNC) terminal as a trigger source. When an external trigger signal is received, the DME1600 starts a single mea- surement or the specified number of measurements.
Page 74: Triggering Through The Remote Interface
Trigger Source Triggering through the remote interface Software trigger In software triggering, a command is sent from a PC to the DME1600. The DME1600 starts measuring when it receives the command. TRIGger:SOURce BUS Internal trigger Internal trigger is the default trigger mode for remote interface operation. In internal trigger mode, the DME1600 triggers immediately when it enters the trigger-wait state.
Page 75: Other Trigger Settings
Other Trigger Settings On the DME1600, you can set the number of samples per trigger, the number of triggers per event, the measured value hold setting, the trigger delay setting for making measurements, and so on. Number of samples per trigger You can configure the DME1600 so that it samples the specified number of times (up to 50000) each time it receives a trigger.
Page 76: Number Of Triggers (Remote Interface Operation Only)
Normally, the DME1600 returns to the idle state upon receiving a trigger. You can set the number of triggers that the DME1600 receives before it returns to the idle state. You can only set this number through the remote interface.

Page 105: Scan Function (Option)
Scan Function (Option) Installing a scanner card option adds a scan function to the DME1600. The following three types of scanner cards are available. • 10-channel scanner card (DME1600-opt01) • 20-channel scanner card (DME1600-opt09) • 10-channel thermocouple scanner card (DME1600-opt12) With the scanner card, you can set the measurement function separately for each channel.
