Changing the Pressure Module During Calibration
The calibration of a pressure instrument may be done using only one
pressure module (internal or external). If you have several pressure
modules available, you may however use a smaller range pressure
module (with greater accuracy) for the instrument's lower range.
Then when the pressure is too high for the pressure module with
smaller range switch to a pressure module capable of measuring
higher pressures.
To change pressure module during calibration do as follows:
Select
F1/ Menu ,
Instrument Input or Instrument Output ,
F2/ Tools ,
Change Pressure Module .
A menu with the following options opens:
MENU ITEM DESCRIPTION
Int. Pressure
(NMPxxx)
The Internal Pressure Module is selected.
Ext. Pressure (EX-
Txxx)
The currently connected External Pres-
sure Module is selected.
Change to
Another EXT
Allows you to remove the currently con-
nected External Pressure Module and re-
place it with another.
To change the External Pressure Module,
do as follows:
1. Select this menu option,
2. Remove the currently connected Ex-
ternal Pressure Module.
3. Wait until MC4 emits a "bleep" in-
forming that the removal of the Ex-
ternal Pressure Module is noticed.
4. Connect another External Pressure
Module.
When the new External Pressure Module
is connected and communicates with
MC4, a window is opened displaying info
of the connected External Pressure Mod-
ule. Select F3/ Ok to continue calibration
Not following these instructions may
result in an interrupted calibration.
