7.2.3
Voltage Measurement
Temperature and humidity range for guar-
anteed accuracy: 23±5°C less than 90%RH
(non-condensation)
Temperature
characteristics
Measurement accuracy × 1 is added to
the accuracy.
When the 9750-11, 9750-12 TEST LEAD
(10 m) is used, the accuracy is not guar-
anteed if the current is below the value
obtained by dividing the test voltage (set-
ting) by 500 G
Ω
.
(when the ambient temperature is
between 28°C and 40°C)
Response time
Within 15 sec. (This is the period of time
after measurement has started until the
displayed value falls within the specified
accuracy range, when averaging is not
used.)
Measuring
range
±50 VDC to ±1.00kVDC, 50 VAC to 750
VAC
Frequency
DC / 50Hz / 60Hz
Measurement
accuracy
±5%rdg. ±5dgt.(The accuracy is guaran-
teed at 50 V or more as an absolute
value. For DC, the accuracy is not guar-
anteed at 1.01 kV or more as an absolute
value.)
Input
resistance
Approx. 10 M
Ω
Temperature
characteristics
Measurement accuracy × 0.5 is added to
the measurement accuracy. (when the
ambient temperature is not 23±5°C)
Response time
Within 3 sec.
