Making Sure That the Input Current Changes Proportionally to External Changes
By properly adjusting the OFS (to adjust the current offset) and FSC (to adjust the maximum
current) variable resistors on the rear panel, you will be able to control the input current
proportionally to the external voltage or resistance. The adjustments are valid for the
specified range. If you change the range, readjust the variable resistors.
A load current actually flows during the adjustment, so connect the power supply that you
want to test.
Making sure that the input current changes proportionally to
external voltage changes
During CV mode adjustment, use the CV variable resistors (the upper row) when you are
using pins 5 and 6 of the EXT CONTROL connector, and use the CC, CR, CV, and CP
variable resistors (the lower row) when you are using pins 1 and 3 of the EXT CONTROL
connector. In all modes other than CV mode, use the CC, CR, CV, and CP variable resistors
(the lower row).

Adjustments during external control
using pins 1 and 3 of the EXT CONT
connector
Turn the load on.
Set the external voltage to 0 V.
Turn OFS until the measured current on the display is 0 A.
Set the external voltage to 10 V.
Turn FSC until the measured current on the display is 100 % of the
selected range.
Turn the load off.
This completes the adjustment procedure.
Turn the load on.
If you are performing proportional control, set the external resistance to
0 Ω. If you are performing inverse control, set the external resistance to
10 kΩ.
Turn OFS until the measured current on the display is 0 A.
If you are performing proportional control, set the external resistance to
10 kΩ. If you are performing inverse control, set the external resistance
to 0 Ω.
Turn FSC until the measured current on the display is 100 % of the
selected range.
Turn the load off.
This completes the adjustment procedure.
