6.3.4 Adjustment procedure
Adjustment items can be roughly classified into two areas: the voltage system and the
current system.
Use variable resistors on the front panel and the variable resistors on the internal PCB
A-200 to perform adjustments.

NOTE
• Variable resistors other than those on the front panel and those on the PCB A-
200 should not be adjusted by the user. Do not disturb the settings of these
variable resistors.
If you inadvertently disturb the settings of any variable resistor other than
those that are user-adjustable, it must be readjusted. Contact Kikusui
distributor/agent.

Voltage system adjustment procedure
The voltage system adjustment includes the following five related items. Adjust
them as follows:
•
Mechanical zero of the voltmeter
• Output voltage offset
• Maximum variable range of constant voltage
• Full scale of voltmeter
• Voltage limit
Connection of equipment
1. Turn off the POWER switch.
2. Connect a DVM to output terminals as shown in Fig. 6-4.
Connect the GND terminal and the - (neg.) terminal with the shorting bar.
