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.
4.3 Programming
SET VAC
When operating in units of either 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 meas-
ure are being set to either mbar or Pa.
1) To properly set the vacuum reading ("zero" point), with the
PGE500 installed on your vacuum system, the gauge should
be evacuated to a pressure below 1.00×10
-4
Torr.
2) Go to the SET VAC screen. When the vacuum system pres-
sure is below 1.00×10
-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 = as ordered]
The unit comes factory preset as ordered. If you like to switch to
another unit, this should be the first parameter that is set. This
will be the units-of-measure (mBAR, TORR, PASCAl) that are
used for all other settings. If your PGE500 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.
