Maybe somebody knows  what is the recommended ambient temperature  to perform  calibration  of  pressure instruments , differential pressure transmitters, RTD,  thermometers?  is there any applicable  standards for this?

RE: Instruments calibration

When calibrating a temperature device your control temperature should compensate or override the ambient effect. For pressure instruments, I would check with the manufacturer, their cells and circuitry are probably slightly different and it would be best to contact them for their recommendation.
Intuitively, I would suggest calibrating them at the same ambient temperature which they operate.
