4)
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
position – the minimum
Multip lier.
7) Set the VOLTAGE SELECT OR switches to the lowest voltag e available.
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 Self-calibration 1
1) Set the RANGE switch to the
CAL
position. (The display will show
CAL 1
. )
The calibration will be verified by the internal calibration circuit. Verify
that the me asured data display indicates a value within the range of
. 970
to
1. 03
.
2) If the value falls within the normal range , the self-calibration is complete.
Set the RANGE switch to a position other than
CAL
. (If self-calibration 1
yields a result within the normal range, the re is no need to pe rform
self-calibration 2.)
5.3 Self-calibration 2
1) Press the SELECT switch while
CA L 1
is being displayed. (The display will
show
CAL 2
; see “4-4 Measurement Condition Setting Display” for more
information.)
2) Incre ase the RANGE switch to the
×
10
2
range.
3) Verify that the screen is displaying values with 5 digits and press the
SELECT switch.
4) This completes self-calibration 2.
Repeat self-calibration 1 and verify
that the value falls within the proper range.
