Information
10 Run the OVP calibration.
Above message is displayed to indicate that the calibration is progressing. It
takes approximately 10 seconds to complete the calibration. If the calibration
fails, an error message will be displayed for a second and you will hear a beep,
and then go back to the OVP calibration mode again.
Current Calibration
11 Select the low-end current calibration point.
12 Enter the computed value (DVM reading
ΒΈ by shunt resistance) by
using the knob and resolution selection keys.
Notice that you should wait for the DVM reading to be stabilized for accurate
calibration during the current calibration.
CALibrating
Connect an appropriate shunt 0.01 W across the output terminals, and
connect a digital voltmeter across the shunt resistor for the current
calibration.
