Hi
Can any body help to clarify the following

questions.

1) What is the minimum gap between the calibrations?

2) What are the methods availed for calibration

For the following instruments


Thermocouples

Temperature controllers

Oxygen probe

The CQI-9 HTSA calls out quarterly as a minimum for calibration of oxygen probes (Question 3.2). The assessment references AMS 2750D for thermocouples (Question 3.3), also quarterly.
