Constant-Voltage Remote Control
1. Output voltage control using external voltage
＊
It is possible to control the output voltage using 0 to 10 V
external voltage.
1) Shut off the POWER switch.
2) Set the offset and FS switches of "V ext. V" on the front
panel to the ON positions with the attached screwdriver.
Connect a cable to the terminals on the rear panel as shown
below.

3) Adjustment procedures
- Apply 0.1 V between the "ext. cont. V" V+ terminal and
"ext. cont. V" - (-S) terminal on the rear panel.
- Press the OUTPUT key to turn on power.
- Rotate the V offset control on the front panel with the
attached adjustment screwdriver to adjust the output voltage
to 1% of the rated voltage.
- Then, apply 10 V between the "ext. cont. V" V+ terminal and
"ext. cont. V" - (-S) terminal on the rear panel.
- Rotate the V FS control on the front panel with the attached
adjustment screwdriver to adjust the output voltage to 100%
of the rated voltage.
