[Step 2.1]
Now input the voltage value (Min) measured by DMM with the knob
and press [ENTER]. During the voltage value input, use the [F/C]
button to switch over the input of 1V step or 10mV step.
Note: The DMM selected for the measurement have the resolution of
three digits of the decimal point at least (1mV). Also the input value
is to take two digits of decimal point of effective value (10mV) and
run off the rest.
[Step 2.3]
Adjust VR311 and adjust the voltage value measured by DMM
according to the voltage displayed in the window, then press
[ENTER].
Note: The DMM selected for the measurement must have the
resolution of three digits of the decimal point at least (1mV).
During the adjustment, the maximum error of the measured
value is ±0.005V.
[Step 3] Current Calibration Steps
Switch the Calibration selection window to current calibration item
with the knob and press [ENTER] getting into current calibration
steps.
[Step 3.1]
Now input the current value (Max.) measured by the DMM with the
knob and press [ENTER]. During the current value input, use the

[F/C] button to switch over the input of 100mA range (100mA/step)
or 1mA range (1mA/step).
Note: The DMM selected for the measurement must have the
resolution of four digits of the decimal point at least (0.1mA).
Also the input value is to take three digits of decimal point of
effective value (1mA) and run off the rest.
[Step 3.2]
Now input the current value (Min.) measured by the DMM with the
knob and press [ENTER]. During the current value input, use the
[F/C] button to switch over the input of 100mA range (100mA/step)
or 1mA range (1mA/step).
Note:The DMM selected for the measurement must have the
resolution of four digits of the decimal point at least (0.1mA).
Also the input value is to take three digits of decimal point of
effective value (1mA) and run off the rest.
[Step 4]
Switch the Calibration selection window to O.V.P. calibration item
with the knob and press [ENTER] getting into O.V.P calibration
steps.
[Step 4.1]
At present, the window will indicate the progress of OVP calibration.
When the calibration is completed, it will jump out of the window.
