AC	350 mV RMS 3.5 V RMS 175 V RMS	± (1% + 0.105 mV)†† ± (1% + 0.00105 V)†† ± (1% + 0.0525 V)††	N/A N/A N/A	AC	100 mV 850 mV 50 V	± 1.1 mV ± 9.5 mV ± 0.55 V

** Accuracy shown is for operation in temperatures from 15°C to 35°C. Annual calibration is required to maintain DVM accuracy.

† DC voltage error increases by 0.1% in the presence of 35 to 100 volts of AC interference.

†† AC voltage accuracy applies to input frequencies of 50 or 60 Hz.
