Temperature probe calibration
Introduction
NOTICE
Do not use electronic simulation of resistance to calibrate the
temperature probe.
NOTICE
Do not calibrate the temperature probe while the vessel is being
controlled to a temperature setpoint.
If the instrument is used in a GMP compatible environment, the temperature
probe is a GMP critical component.
Note:
The temperature probe must be calibrated by a calibration technician.
The temperature probe is calibrated using an offset.
The probe tip may contain one or two temperature sensors (RTDs), depending
on your instrument configuration. Both sensors have to be calibrated simulta-
neously.
Note:
Preparation
Before you start to calibrate the temperature probe, prepare the following:
•
Temperature calibration instrument
The accuracy of the temperature calibration instrument is the responsibil-
ity of the site metrology department.
Note:
•
Constant temperature circulating bath
If additional circulating baths are available, they can be set to the two end-
point calibration temperatures. This would allow to shorten the total cali-
bration time, as there would be no need to change the temperature of the
primary circulating bath.
