5.
Press the AC/DC/EXT key (SHIFT+V) to set the OUTPUT mode to
EXT-DC.
The EXT and DC LEDs illuminate.

6.
Press the RANGE key (SHIFT+I) to set the voltage range (135 V or 270
V).
The LED corresponding to the voltage range illuminates.
AUTO cannot be selected.

7.
If an AC voltage is being applied, press the F key to set the frequency
(40 Hz to 500 Hz).
To display the measured value accurately, set the frequency so that it matches the
frequency of the external input signal. If the set frequency is out of synchronization,
the measured value will be unstable.
8.
Apply an external signal to the INPUT terminal.
9.
Turn the OUTPUT on.
Setting limit values
page 44
You can set the frequency limit (40 Hz to 500 Hz), the current limit (0.1 A to 4.2 A),
and the current limit operation (TRIP or LIMIT CONTROL).

Fine adjusting the offset
You can fine adjust the offset by turning the OFFSET variable resistor using the
adjustment screwdriver. Adjust the offset so that the output voltage is as close to 0 V
(DC) as possible with the
ATT switch turned off and the input terminal shorted.
Fine adjusting the gain
You can fine adjust the gain by turning the GAIN variable resistor using the
adjustment screwdriver. Adjust the gain so that the output voltage is 135 Vac (135 V
range) when 1.35 Vac is applied to the input terminal with the
ATT switch turned
off.
Measured value display
page 42
The lower numeric display shows RMS, PEAK, AVG, and W in order each time the
I key is pressed.
The upper numeric display shows the average measured voltage if AVG is selected
on the lower numeric display. Otherwise, the upper numeric display shows the
measured RMS voltage.
