Action
Set the circulating bath temperature to one of the calibration end point
temperatures; or use another bath if available. Repeat steps 3 to 5 above.
Set the circulating bath temperature to the other calibration end point
temperature; or use another bath if available. Repeat steps 3 to 5 above.
Evaluate the obtained results considering the following:
Manufacturer's tolerance: ± 0.5°C
•
Process tolerance: determined by the end user.
•
Action
Using the data obtained during the calibration procedure, calculate the
offset to adjust the probe temperature to the recorded standard probe
temperature:
Offset = standard temperature reading - probe reading.
Note:
Use the data obtained at operating temperature (the middle calibration point)
for best overall accuracy.
If the probe contains two temperature sensors, calculate the offsets for both
sensors.
