50 PMC-A
3.
Turn the VOLTAGE knob clockwise until constant
current operation is achieved.
Offset adjustment is always performed under constant current
operation.
4.
Adjust Iout OFS (Variable resistor D) so that the out-
put current (a value calculated from the external
DVM reading and shunt resistance) is 0 A.
5.
Turn Iout OFS (variable resistor D) 1 to 1.5 scales
(angle of approx. 30 to 40 degree) counterclockwise.
6.
Set the output current to the rated output current.
When operating by the front panel (local control), turn the
CURRENT knob clockwise all the way. When using ana
-
log remote control, set the control signal to 10 V or 10 kΩ.
7.
Adjust Iout MAX (Variable resistor B) so that the out-
put current (a value calculated from the external
DVM reading and shunt resistance) is slightly higher
than the rated current.
When the rated output voltage is set, operation
mode of the slave unit changes from CC to CV.
(Type I model only)
Readjust the output voltage at full scale in the following proce-
dure. See page 67, Test equipment required for calibrationfor
the test equipment required and environment. See Fig. 6-2 for
the connection of the equipment.
・Do not set the output voltage greater than or equal
to 105 % of the rated voltage for this adjustment. If
you do, the power supply may malfunction.
■ Adjustment procedure
1.
Set the output voltage to the maximum output volt-
age.
