Using external DC bias signal source
Connect the DC standard power supply to EXT DC BIAS INPUT and make sure that the output of the
standard power supply is 0V. Turn ON the external DC bias ON/OFF switch and press ON of the SIGNAL
switch.
While reading the value on the voltmeter or oscilloscope connected to the voltage monitor, increase the
output level of the DC standard power supply gradually and set the desired voltage.

High voltage display
When the output voltage exceeds ±130V to ±150V, the high voltage output LED lights and starts
rotation slowly. The higher the output voltage is, the faster the rotation is.
When the voltage exceeds ±4.9 kV, the color changes from orange to red.
Gain adjustment with RESPONSE
The gain of the 200 Hz band or more may vary depending on the RESPONSE knob position. Refer to
"5.3 Characteristics in constant voltage mode, Chapter 5".
When the frequency is used at 200 Hz or more, measure the output voltage of the voltage monitor and
adjust RESPONSE so that the desired amplitude may be obtained.
