[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: Refer to
[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. Add 0.5% to
the specified accuracy if the signal measured is in the range of 10 A to 20 A and
for a period of up to 30 seconds. After measuring current >10 A, leave the meter
to cool down for a period that is twice the measuring time used before
application of low current measurement.
[6] Input current < 3 Arms.
