ZONE CALIBRATION
Due to tolerance variations or other factors, you may need to
program an offset to calibrate the sensor. 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.
The 2800 will say “Enter Zone Number.”
3. Press the corresponding Zone key (1–8).
The 2800 will say “Enter Number.”
