4.1 Troubleshooting Guide
Malfunction or incorrect operation may be caused by:
1.
Reversed polarity:
Check the wiring using
Figure 2-2
as a guide. If the temperature
of the thermocouple increases while the current magnitude
decreases, the problem could be caused by reversed polarity of
the:
a)
thermocouple wiring
b)
power supply leads
c)
monitor instrument
