CH1 to CH4 show the counts after A/D
conversion of inputs to channels 1 to
4.
For RD2800, the RJ (reference
junction compensation) count is
displayed next to CH4.
RJ is the counts after A/D conversion
of the reference junction
compensation (RJ). RD2800 has no
Count 2 display as RJ is displayed in
Count 1 display. RJ is displayed only
when there is a channel, of which RJ
is programmed to “1: enable” in the
range programming. When all
channels are programmed to “0:
disable”, (- - - -) is displayed.
