DC voltage measurement typical accuracy:
600 mV, 6 V, 60 V & 600 V range; ± 1.5% of range
DC current measurement typical accuracy:
60 uA & 600uA range; ± 1.2% of range
6 A range; ± 2.0% of range

Note:
- If used in close proximity to an RF transmitter or when subjected to continuously present electromag-
netic phenomena, some recoverable degradation of performance may occur.
Temperature coefficient 0.1 × (specified accuracy) / °C (from –10 °C to 18 °C, or 28 °C to 55 °C)
Common Mode Rejection Ratio
(CMRR)
> 100 dB at DC, 50/60 Hz (1 kΩ unbalanced)
Please take note that for the product, the warranty does not cover:
Damage from contamination
Normal wear and tear of mechanical components
Manuals, fuses, and batteries
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.
