Duct Temperature Transmitter 5
Publication 1414-IN005B-EN-P - July 2010
Field Calibration
The unit can be calibrated in the field by using precision resistor values equal to the zero and
span of the transmitter temperature range.
1. Disconnect the sensor from the transmitter and connect the resistor that represents the
zero value to the EXC and NEG terminals.
2. Adjust the ZERO pot until the desired output is achieved.
3. Connect the resistor that represents the span value to the EXC and NEG terminals.
4. Adjust the SPAN pot until the desired output is achieved.
Repeat these steps until no further adjustment is required.
Specifications
TIP
If the unit uses a three-wire sensor, a jumper must be placed between EXC and
SEN.
