Confirm that the accessory shorting plug is inserted into HV-EN
connector on the rear the unit.
5) Leave the Rx

measuring terminals free at this stage – do not connect
the measuring rods and the sample to be measured to the terminals.
6) Set the RANGE selector switch to the
×
1 p osition – the minimum
Multip lier.
7) Set the VOLTAGE SELECTOR switches to the voltage to be applied to
the sample.
8) Turn the POWER switch ON.
Allow the unit to warm for a minimum of 30 second s to ob tain the
specified performance. However, a measurement can be done after a
warm-up of several seconds.
5.2 Calibration
1 ) CAL1 Calibration
＊ １
Set the RANGE selector switch to the CAL position.
The LCD display shows the CAL1 message in the lower left area of the
screen. When the unit is normal, the measured value indication area
should show a value within a rang e from .970 (-3%)to 1.03 (+3%).
I f the CAL2 calibration is not needed, set the RANGE switch to a position
other than the CAL .
2 ) CAL2 Calibration
＊ ２
To perform the CAL2 calibration, press the SELECT switch to start the
CAL2 , replacing the CAL1 message with the CAL2 .
Set the RANGE switch to the
×

position.
When the 5-digit value indication on the LCD display is stabilized with its
5 th p lace within a value of 4 peak to peak , the unit is normal.
To finish the CAL2 calibration, pre ss the SELECT switch.

This function is inte nded to check
the accuracy of the measuring voltage
and the integrity of the current
me asuring circuit.
＊ ２
T his function is intended to measure
the offse t. An offset value is stored in

PROM and is subtracted from
subsequent the measured value.
