Measurement range acc. to EN 61557-4: 0,10…999 Ω
Range | Resolution | Accuracy |
0,00…19,99 Ω | 0,01 Ω | ±(2% m.v. + 3 digits) |
20,0…199,9 Ω | 0,1 Ω | |
200…999 Ω | 1 Ω | ±(4% m.v. + 3 digits) |
DC and AC voltage measurement
Range | Resolution | Accuracy |
0…299,9 V | 0,1 V | ±(3% m.v. + 2 digits) |
300…750 V | 1 V | ±(3% m.v. + 2 digits) |
The acronym “m.v.” stands for a “measured reference value”.
