Functions
The following functions can be performed from CB2:
•
Read sensor type, serial number, date of factory calibration and the date of
last field calibration.
•
Read current pressure and output signal.
•
Set output signal range (4-20 mA) down to 20% of the cell's range. The
output signal may be inverted.
•
Calibrate pressure measurement and output signal.
•
Test accuracy and print a test protocol.
•
Restore factory calibration.
•
Read and check the sensor's internal memory.
