6.9 Calibration Examples
Temperature calibration with the comparison method
DESCRIPTION
The user has to calibrate a temperature element (RTD or TC) in the field.
Accordingly, customer needs:
■ to measure the signal coming from the RTD or TC under test (DUT)
■ to measure the reference signal coming from the reference RTD or TC
■ to have a temperature generator
UP TO NOW
User has to carry in the field:
1. a standard calibrator to measure the TC or
RTD signal coming from the DUT
2. an external indicator to measure the
reference signal coming from the reference
TC or RTD
3. a dry block to generate the temperature
FROM NOW
User can use :
1. the PASCAL ET II ( 2 Input) to:
■ measure the TC or RTD signal coming
from the DUT
■ measure the reference signal coming
from the reference TC or RTD
2. a dry block to generate the temperature
ADVANTAGES
1) customer can buy only ONE CALIBRATOR, doesn’t need to buy two devices
– COST SAVINGS
2) customer has to carry in the field only ONE CALIBRATOR and no more two
devices – EASIER JOB
3) customer can run the calibration directly on the calibrator, storing the
calibration data – FASTER CALIBRATION – TIME & COST SAVINGS
