Calibration
1. In the calibration window: press F3/ Start .
2. Set the pressure using, e.g. a pressure pump. Aim for the cal-
ibration point's target value as shown on page 131.
3. How a calibration point is accepted depends on the procedure
settings of the instrument at hand:
• If Automatic Calibration Point Acceptance is set
(checked), the input and output values of the current
point are saved automatically. Automatic acceptance
settings are presented in chapters Procedure Data
Page on page 165 and Accepting Calibration Points
Automatically on page 178.
• If Automatic Calibration Point Acceptance is not
set, accept the point using F3/ Accept Function Key.
Note that this functionality is also available when Au-
tomatic Calibration Point Acceptance is set. This
allows you to save results when the input and/or output
signals are permanently unstable.
4. Proceed to next calibration point (step 2) if applicable. When
the calibration run is ready, save or reject the results as de-
scribed in chapter A Calibration Procedure Using MC4 on
page 130.
5. Either do another calibration run, adjust the instrument or end
the calibration by selecting F1/ Menu , Close .
Notes.
For information on how to zero a pressure module, see chapter Ze-
roing a Pressure Module During Calibration on page 180.
For information on how to change pressure module during calibra-
tion, see chapter Changing the Pressure Module During Calibra-
tion on page 179.
Hint!
These instructions can be adapted for any kind of transmitter.
Change the input signal connections/settings according to the in-
strument's input signal. When calibrating another kind of pressure
instrument, use this example as the source for the input signal part.
When measuring absolute pressure while using high pressure Pres-
sure Modules, you may enter manual barometric pressure in the win-
dow that opens by pressing F1/
Menu , Instrument Input .
