Instrument Calibrations and Accuracy
Adjustments
AM8060 is designed for temperature measurements by measuring a
probe’s resistance and converting it into temperature. Consequently,
the resistance measurement is very critical, and the instrument must be
calibrated correctly. Every AM8060 is calibrated before shipment.
AM8060 needs regular calibration performed by qualified
professionals. A one year calibration interval is recommended.
Users can calibrate AM8060 using standard resistors with calibrated
values.
Warning: It is required to set correct R0 (or Rtpw) values in Sensor 1
(S1) before calibrations. To calibrate AM8060 in the range from 10 Ω
to 50 Ω, R0 (or Rtpw) needs to be set to 25 Ω. To calibrate AM8060 in
the range from 50 Ω to 375 Ω, R0 (or Rtpw) needs to be set to 100 Ω.
In the event of AM8060 being out of tolerance, its accuracy can be
adjusted by re-calibrations. Standard resistors of 25 Ω and 100 Ω are
needed for AM8060 calibrations.
The calibration should be done in an environment with room
temperature of 22 ± 2°C.
