TEMP SLOPE
WARNING
TB82
High or low temperature
slope
Verify sensor wiring connections and
inspect cable for shorts. Remove all poten-
tial shorts to ground, conduit or metals.
Verify that sensor had 10 to 15 min. to accli-
mate to temperature environment to which it
was calibrated.
Disconnect temperature compensator leads
from transmitter and measure resistance.
Replace sensor with spare when transmitter
does not accept calibration values.
