1) Accuracy:

Place appropriate number of calibrator sensor of Temperature near Temperature sensor (Enviro/Master sensor) of stability chamber based on the number of sensors present in the stability chamber.
Record the Temperature for accuracy study at 5 minutes intervals for the time duration specified for 1 hour.

Acceptance criteria:

1) For accuracy: difference between temperature of calibrator & stability chamber temperature should be within the specified limits of ± 1°C respectively.

2) For verification: Difference between temperature of calibrator & temperature sensor should be within the specified limits of ± 2°C respectively.

Remark: The instrument calibration is Satisfactory / Not Satisfactory.

Calibration: Scheduled / not scheduled
