Warming-up
• To minimize adjustment error affected by initial drift, warm
up the unit at least 30 minutes before starting adjustment.
7. Set the output current to the rated output current.
For local control, turn the CURRENT control knob fully clock-
wise. For remote control, set the control signal to 10 V or 9.5 k
Ω
.
8. Turn on the OUTPUT switch.
9. Turn off the OUTPUT switch 30 minutes or more later.
Output current offset
10. Set the output current to 0 A.
For local control, turn the CURRENT control knob fully counter-
clockwise. For analog remote control, set the control signal to 0
V or 0
Ω
.
11. Turn on the OUTPUT switch.
12. Turn the VOLTAGE control knob clockwise until the unit
enters constant current operation. (Offset adjustments
must always be conducted in constant current operation.)
When the voltage is remote-controlled externally and the voltage
setting is 0 V, the unit may operate at a constant voltage, depend-
ing on the offset balance. To avoid this problem, turn the voltage
control knob so that a voltage equal to about 10 % of the rated
value can be provided at any time.
13. Using variable resistor "6", adjust the output current to 0 A.
