U1252A AC Specifications
Ta b l e 7 U1252A AC Accuracy ± (% of reading + No. of Least Significant
Digit)
[1] The additional error to be added as frequency >20 kHz and signal input<10 %of
range: 3 counts of LSD per kHz.
[2] Input impedance: > 1GHz for 50 mV to 1000 mV. Input impedance is 1.1 MΩ
(nominal) with <100 pF for 5 V to 1000 V ranges.
[3] The input signal is lower than the product of 20,000,000 V-Hz (product of voltage
and frequency).
[4] Input current >35 μArms.
[5] Current can be measured from 2.5 A up to 10 A continuously. An additional 0.5%
needs to be added to the specified accuracy if the signal measured is in the
range of 10 A to 20 A for 30 seconds maximum. After measuring a current of
>10 A, leave the meter to cool down for twice the measuring time used before
application of low current measurement.
[6] Input current < 3 Arms.
