1) Remove the instrument from its case.
2) For out 1 and 2 it is possible to select the
desired output type by setting the J304 and J305
jumpers.
J304 (AL1, Cool.) 1-2 = SSR 2-3 = Relay
J305 (OUT 1) 1-2 = SSR 2-3 = Relay
3) For out 2 it is possible to select the used relay
contact (NO or NC) by setting J303 jumper.
J303 (AL1, Cool.) 1-2 = Out NO 2-3 = Out NC
Note : J303 is a soldering jumper and it is located Note Note Note Note
on the soldering side of the card.

These device are capable to detect leads break
for TC and RTD inputs. For RTD input it shows
this status as an overrange condition.
For thermocouple input only, it is possible, to
select the overrange indication (standard) by
closing CH2 and opening SH2 or underrange
indication by closing SH2 and opening CH2.
SH2 and CH2 are located on the soldering side of
the CPU card (see fig.12).
