5. INSPECTION AND CHECK PROCEDURES
(4) Press the [DISPLAY] key until the menu shown below appears.
(5) Input the reference voltage for each range according to the table below, and then check that the level of
measurement is within the rating.
Voltage precision ratings
Range Input voltage Rating
20 mV +20.000 mV +19.984 mV to +20.016 mV
50 mV +50.000 mV +49.96 mV to +50.04 mV
100 mV +100.00 mV +99.92 mV to +100.08 mV
200 mV +200.00 mV +199.84 mV to +200.16 mV
500 mV +500.00 mV +499.6 mV to +500.4 mV
1 V +1.0000 V +0.9992 V to +1.0008 V
2 V +2.0000 V +1.9984 V to +2.0016 V
50 V +50.000 V +49.96 V to +50.04 mV
This value will change
when the reference voltage
is input from the voltage
generator.
(6) Press the [START/STOP] key when the input voltage stabilizes.
