Open input circuit
This instrument is able to identify an open circuit for TC
and RTD inputs. The open input circuit condition for RTD
input is shown by an “overrange” indication. For TC
input, either an overrange indication (standard) or
underrange indication can be selected from the following
table:
2HS 2HC noitacidnI
nepoesolc)tluafed(egnarrevo
esolcnepoegnarrednu
Both pads are located on the solder side of the CPU card.
CAUTION: Solder carefully to avoid damage to PCB or
other components.
