Current and OCP calibration
12 Pressing the Calibrate key saves the new calibration
constants for OVP circuit and goes to the current
calibration mode.
CAL SETUP 3
A CALIBRATING message appears for about several seconds
to indicate that the OVP calibration is progressing and
new calibration constants of “SETUP 2” are stored. Then,
the display shows the above message to indicate that the
power supply is ready for the current calibration.
If the calibration fails, a OVP CAL FAIL message appears for
one second and the display shows the CAL SETUP 2 for OVP
calibration again.
13 Select the low current calibration point.
I LO 0.2000 A
The display shows the low current calibration point.
14 Read the DVM and change the low current value on the
display to match the computed current (DVM reading
divided by shunt resistance).
For example, if the computed value is 0.199 A, adjust the
current to 0.199 A using the knob and arrow keys.
I LO +0.1990 A
NOTE
Connect an appropriate shunt (0.01 Ω) across the output terminals, and
connect a digital voltmeter across the shunt resistor for the current
calibration.

NOTE
Notice that you should wait for the DVM reading to stabilize for accurate
calibration.
