11. Electrically Noisy Environments
AC power lines can be the source of electrical noise. If the datalogger is in an
electronically noisy environment, the 107/107B temperature measurement
should be measured with the AC half bridge (Instruction 5) with the 60 Hz
rejection integration option on the CR10(X) and slow integration on the 21X
and CR7 (see Section 13 of the datalogger manual for more information on
noise). Instruction 11's fast integration will not reject 60 Hz noise.
