Typical value. Resolution is defined as the RMS noise of DCV 20 V range (set auto zero to “Once”).
[2]
Normal mode rejection ratio for power frequency ±0.1%. For power-line frequency ±1%, subtract 20 dB. For ±3%, subtract 30 dB.
[3]
Maximum rate for DCV, DCI, 2-wire resistance and 4-wire resistance functions.
[4]
The basic DC accuracy specifications include RMS noise at 100 PLC. For <100 PLC, add “RMS Noise Adder” to the basic DC accuracy specifications.
