Maximum Allowable Source Resistance: 20k ohm on most
sensitive range, no restriction on other ranges.
Normal Mode Rejection (at line frequency): > 30 dB (18
dB/octave roll-off above 60 Hz).
Common Mode Rejection: Conditions for the following data are
DC or line frequency AC with up to 1K ohm between the
positive input and negative input, and the negative input
connected to the guard terminal. Maximum allowable DC
or DC plus peak AC common mode voltage is 500V.
