Offset Adjustment - B+B Sensors A307 Operation Manual

OPERATION MANUAL

Offset adjustment

The OFFSET controls are set at the factory to allow for the variations found in standart thermocouples. By adjusting
the OFFSET controls, you can optimize measurement accuracy for a particular thermocouple at a particular tempera-
ture.
Adjusting for Accurate Measurements
1. Connect the thermocouple to the input connector and turn the thermometer ON, then press the 0.1° key to select
the high display resolution.
2. Playe the thermocouple in a known, stable temperature environment at or near the temperature you wish to mea-
sure, and allow the readings to stabilize.
3. Slowly adjust the OFFSET control so that the thermometer reading matches the temperature of the known environ-
ment. Leave sufficient time between adjustments to allow for meassurment lag.
4. The calibration of the thermometer-thermocouple combination is now optimized for measurements near the tempe-
rature measured in step 2.
Resetting the OFFSET Control
To return the OFFSET control to their factory setting without having to recalibrate the thermometer, perform the
following procedure:
1. Connect a thermocouple that is in good working order to the input that is to be adjusted.
2. Place the thermocouple in an ice-water bath and allow the reading to stabilize.
3. Slowly adjust the OFFSET control until the thermometer reads 0°C (32°F)
