Current Calibration
For current calibration, connect an appropriate shunt 0.01
Ω
across the output
terminals, and connect a digital voltmeter (DVM) across the shunt resistor. Same
as voltage calibration, you will also be calibrating for low current, middle current
and high current calibration point respectively. Make sure that the power supply is
in constant current (CC) mode along the current calibration.
1 Current calibration mode
– Display will show “C” blinking.
– The CC annunciator will be turned on.
– Ensure that the power supply is in CC mode. Otherwise the CV annunciator
will fast-blink.
2 Low current calibration point.
– Display will show “C” blinking.
– The M1 annunciator will be turned on.
– Use the knob to enter the computed value (DVM reading divided by shunt
resistance).
– Press the “Memory” button to save the changes and move to the next
calibration point. You will be able to perform this if the power supply is in
CC mode.
