Line noise normal mode rejection: ≥ 100 dB

Magnitude of the effects of normal mode 50/60 Hz noise,

with the most appropriate line noise filter frequency setting.

Each input circuit has a CR filter of sufficient large time

constant so that there will be little effect of line noise such

as 500 mV AC superposed on a thermocouple or ±60 mV

input.

Common mode noise rejection

Magnitude of the effects of voltages applied across the

terminal C and the ground terminal when there is no

potential difference among all the C terminals.

DC: N/A

AC, ±3 V, ±6 V, ±12 V: Approx. 86 dB

AC, other ranges: Approx. 120 dB

Common mode noise rejection between channels

Magnitude of the effects of DC/50/60 Hz voltages applied

across the terminals C of the present and the last scanned

channels.

DC, ±3 V, ±6 V, ±12 V: Approx. 100 dB

DC, other ranges: Approx. 120 dB

AC, ±3 V, ±6 V, ±12 V: Approx. 86 dB

AC, other ranges: Approx. 106 dB
