[Step 2]
When get into Calibrated item selection window, set the cursor to the
calibrated item by using the knob and press [ENTER]. After the
calibrated item is selected, proceeding voltage, current and over-
voltage calibration step by step.
[Step 3] Voltage Calibration Steps
After the channel is selected, set the cursor to [voltage] by using the
knob and press [ENTER] getting into voltage calibration procedure.
[Step 3.1]
After the proper measured setting has been done according to the step
displayed in the window, press again [ENTER] to get into voltage
value input window.
[Step 3.2]
Input measured voltage value directly by using the number key, and
press [ENTER] to complete the measured voltage (MIN) input (When
the value has been input by mistake, but not yet pressed [ENTER],
can use the knob to clear the value.)
Note: The DMM selected for the measurement must 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 3.3]
After the proper adjustment of measured value has been done
according to the step displayed in the window, press [ENTER] to
complete Maximum voltage adjustment. The DMM selected for the
