20.3.3. Pressure transducers (channels 61~70)
Pressure transducers use the calibration provided by the
transducer manufacturer. This calibration is already pro-
grammed in the DEF Configuration Editor program. This will
provide an accuracy of better than 1% of full scale. If you have
pressure sources and calibrated pressure measurement
equipment with a higher accuracy, it is possible to calibrate
the pressure sensors as follows:
1. Verify that no actual or residual pressure is being applied to
the sensor which you want to calibrate. Zero the pressure
transducer using the handheld controller or using WinDyn:
1.1. Using the handheld controller:
Select Autozero (F), then Single Channel (C).
Select the pressure channel to zero .
Select Exit (E).
1.2. Using WinDyn:
Select Calibrate channels from the main menu.
Select the pressure channel to zero.
Select
Zero.
Select Done.
2. Apply a pressure to the pressure sensor using a controlled
(constant) pressure source
3. Measure this pressure with your calibration equipment
4. Calibrate the sensor using the handheld controller or using WinDyn:
4.1. Using the handheld controller:
Select Configure (I), then Calibrate (B), then Edit (C).
Select the pressure channel to which the pressure is being
applied.
Select
Current Value (C).
Enter the correct value obtained in 2. above and press
Enter (
