9. Press the “NEW TEST” option to clear the data and perform
another test.
10. Press the “DONE” option to end the test and return to the
standard pressure setting.
Example:
[P1] ST will return to [P1].
Important NOTE: The previous example uses a normally closed
switch. The basic procedure is still the same for a normally open
switch, the display will just read “OPEN” instead of “CLOSE”.
7. Calibrating Transmitters
7.1 Using the mA Input Function
The mA input function allows the user to read back the 4-20 mA
output from the device being calibrated. This can be done in one
of two ways.
1) Passively - Where the device under test directly generates 4-20
mA and can be read by the calibrator.
2) Actively – Where the calibrator supplies 24 VDC loop power to the
device under test to power the device while reading the resulting
4-20 mA signal.
