Startup and Basic Operation
Connecting and Removing External Pressure Modules
An external pressure module may be connected and removed at
any time. If a removed module was part of an active measurement,
MC5-IS automatically changes the measurement to a suitable in-
ternal pressure module. MC5-IS also emits a “beep” to inform you
of the fact that the external pressure module used for pressure
measurement was disconnected.
Zeroing a Pressure Module
If the selected pressure module does not display zero gauge pres-
sure when the applied pressure is zero, the module has to be ze-
roed.
Open the appropriate window setup menu (
D/Menu, A/Window 1
Setup or B/Window 2 Setup) and select menu option 7/Zero Pres-
sure Module. If a secondary pressure module is active in the se-
lected window, a pop-up menu will appear for choosing either to
zero the primary or the secondary pressure module.
NOTE!
Zeroing a pressure module is especially important when the
operating position of MC5-IS is changed or the location of MC5-
IS is changed in the vertical direction. Both of the above men-
tioned factors affect notably on the pressure measurement
modules. Measuring pressure below 100 mbar (approx. 40 iwc)
should be done with a firmly mounted MC5-IS (e.g. placed on a
table top).
