Analog Input 2 can be used only with THC inputs if Analog Input 1 is also used as a THC input.
*** To connect the CJ, put LK3 into position B. To disconnect the CJ put LK3 into position A.
**** For mA input types, to ensure loop continuity when the CMF310 controller (or CMF160 indicator) is switched off, fit a 2V7 Zener diode
Note. 3-lead RTD: 3 leads must have equal resistance, not exceeding 20  each.
