ZONE CALIBRATION
Due to tolerance variations or other factors, you may need to
program an offset to calibrate the sensor Zones. The offset can
range from -15 to +15 for Zones configured as temperature, and
-100 to +100 for Zones configured as 4–20mA. Setting a positive
number will add that number to the Zone reading. Setting a negative
number will subtract the programmed value from the Zone reading.
For instance, if a temperature sensor consistently read two degrees
high, you could use the calibration feature to adjust that temperature
down two degrees. To make a value negative, precede the value
with the [RINGS/TAD/*] Key.
To calibrate a Zone:
1. Press the SET key.
2. Press the CALIBRATE key.
1800 will say “Enter number.”
3. Press the corresponding Zone key (1–8).
1800 will say “Enter number.”
