Measurement Tolerances; Direct Current; Alternating Current - VOLTCRAFT VC-540 Bedienungsanleitung

measurement tolerances

Statement of accuracy in ± (% of reading + display error in counts (= number of smallest
points)). The accuracy is valid for one year at a temperature of +23 °C (± 5 °C),
and at a relative humidity of less than 75%, non-condensing. Temperature coefficient: +0.1 x
(specified accuracy)/1°C

Direct current

range
5000 mA
80 A
Overload protection 600 v
DC accuracy: After DC zeroing (REL)
*Accuracy is valid for the range of 5 to 100% of the measuring range

alternating current

range
5000 mA
80.0 A
Frequency range 50 - 60 Hz; real effective measurement (True RMS) for sine-shaped
signals
Overload protection 600 v
*Accuracy is valid for the range of 5 to 100% of the measuring range.
Below 10 % of the measuring range, a measuring fault of 12 counts must be added.
