Specification Assumptions
Accuracy is given as ±(% of reading + counts of least
significant digit) at 23 °C ± 5 °C, with relative humidity
less than 80% RH.
AC V and AC A specifications are AC coupled, true rms
and are valid from 5% of range to 100% of range.
The crest factor may be up to 3.0 at full- scale (4000
counts)
For non- sinusoidal waveforms, add (2% reading + 2% full
scale) typical.
After VZ
LOW
(low input impedance) voltage measurements,
wait at least 20 minutes for thermal impact to cool before
proceeding with any other measurement.
WARNING
Exceeding the crest factor limit may result in an incorrect or a lower
reading. Do not exceed the crest factor limit to avoid instrument
damage and the risk of electric shock.
