4 Setup and Operation
4.1 User Interface Basics
The user interface is designed for easy operation and a
natural progression of setup parameters. This section gives a
brief explanation of operation for added clarity.
There are four soft-keys located on the front panel, two on
each side of the display. These keys are used to select and
program the various functions available. During programming
Programming soft-keys
of the CVM201, the display will identify what function each
key represents.
To begin programming, press any one of the four keys. The display will indicate a choice of functions. Press the
key indicated by the function on the display to continue with the programming of the parameter desired. After
setting the various parameters, press the SAVE key to save the new setting and return to the main screen. To
continue setting additional parameters, scroll forward with the MORE key until you reach the desired
parameter.
4.2 Programming
SET VAC
When operating in units of either mbars (mbar) or pascals (Pa), you must perform SET ATM
before setting the vacuum reading (SET VAC). See SET ATM below. Failure to do so will result in improper
operation of the gauge. If you change units of measure or reset to factory defaults, then this same procedure
must be followed again if the units of measure are being set to either mbar or Pa.
1. To properly set the vacuum reading (“zero” point), with the CVM201 installed on your vacuum system,
the gauge should be evacuated to a pressure below 1 x 10
-4
Torr.
2. Go to the SET VAC screen. When the vacuum system pressure is below 1 x 10
-4
Torr, press the PRESS TO
SET VAC key. The zero point (displayed pressure reading with gauge exposed to vacuum) is now set.
UNITS [Factory default = TORR]
This should be the first parameter that is set. This will be the units-of-measure (TORR, mBAR, PASCAl) that are
used for all other settings. If your CVM201 has been previously configured and relay setpoints and linear analog
output pressure settings have been programmed, changing units-of-measure will return the relays setpoints and
the linear analog output pressure settings to factory default setting values in TORR. In this case, you must
reprogram the relay setpoints and linear analog output pressure settings in the newly programmed units-of-
measure.
