2.0 Specifications
The following specifications should be considered under the environment specified.
To meet its specified accuracy specs, allow a warm up for at least one-half hour.
It is important to note that a DMM specified range is expressed as a numeric value indicating the highest
absolute voltage that can be measured. The lowest value that can be detected, or sensitivity is expressed
by the corresponding resolution for the range.

DCV Noise Rejection Normal Mode Rejection, at 50, 60, or 400 Hz ± 0.5%, is better than 95 dB for
apertures of 0.160s and higher. Common Mode Rejection (with 1 k lead imbalance) is better than 120
dB for these conditions.
