10 Run the OVP calibration.
The above message is displayed to indicate that the calibration is in progress.
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 return to the OVP calibration mode again.
Current calibration
11 Select the low-end current calibration point.
12 Enter the computed value (DVM reading divided by the shunt resistance) by
using the knob and resolution selection keys. Notice that you should wait for
the DVM reading to stabilize for accurate calibration during the current.
calibration.
13 Save the changes and select the middle current calibration point.
If the entered number is within an acceptable range, an ENTERED message
appears for a second. If the entered number is not correct, an error message
will be displayed for a second and you will hear a beep, and then return to the
low, middle, or high current calibration point again as proceeding.
CALIBRATING
Connect an appropriate shunt 0.01
Ω
across the output terminals, and connect a
digital voltmeter across the shunt resistor for the current calibration.
