When the display has stabilized, check the value.
If the indication is unstable, enable the lter function. An average of the
measured value is displayed.
See “3.5 Filter Function” (p. 47).
6
With the test leads connected to the object under measurement, press the
MEASURE key to end measurement.
The last measurement is retained ([HOLD] is lit) and voltage generation and
measurement are stopped.
PI DD
Automatically switches every two seconds.

When measuring for 1 min. or more, the 1-min. value can be displayed with the
or key, either during or after measurement.
7
Discharge the electric charge that remains in the object under
measurement.
After measurement has been completed, the discharge circuit in the instrument
automatically discharges the electric charge remaining in the object under
measurement.
See “3.4 Automatic Discharge Function” (p. 46).
Retention of the measured value
IMPORTANT
The retained measured values are cleared when power is turned o. To save the
data, use the memory function.
See “Recording Measurement Data (Data Memory Function)” (p. 85).
Deleting the retained data
To clear the data, press the CLR key.
