ANALOG TYPE
[Factory default = as ordered]
Select "NONLIN" for non-linear (S-Curve) or "LOG" for log-linear
analog output (See Analog Output section).
AOUT CAL
[Factory default = Factory Set]
This has been pre-set in the factory and is used to optimize the
analog output calibration. It is recommended that the user not
make this adjustment unless the displayed pressure on the
PGE500 and the resulting pressure calculation from the analog
output do not match closely. To perform this adjustment, connect
the PGE500 analog output to a high resolution voltmeter, your
system, PLC, etc. While in the AOUT CAL screen and with the
gauge exposed to atmosphere, use the INC or DECR soft-keys
to adjust the analog output to match the corresponding pressure
displayed on the screen. Example: The PGE500 ANALOG TYPE
menu above is set to LOG. In the AOUT CAL screen, the atmos-
pheric pressure is displayed at 760 Torr. Based on the equation
and table given in section 7.3 the expected analog output at
760 Torr is 7.881 V. Use the INC or DECR soft-keys in the
AOUT CAL screen to set the analog output to 7.881 V as rec-
orded by your voltmeter, PLC, etc. Alternatively, if the analog
output is used to display the pressure in your PLC or system
display console, adjust the AOUT CAL while the gauge is ex-
posed to atmosphere so that the atmospheric pressure displayed
by your PLC matches the atmospheric pressure displayed by the
PGE500. The AOUT CAL can be performed at any pressure
between 400… 999 Torr (atmosphere recommended).
SCREEN SAVER
[Factory default = ON]
The PGE500 uses an OLED type display which over an ex-
tended period of time can start to show divergence between
pixels that are on at all times verses pixels that are not. This
could result in pixels exhibiting a burned-in effect. To minimize
the burned-in effect, a screen saver function can be activated by
programming the SCREEN SAVER menu selection to ON. With
the screen saver function turned on, the display appearance
changes every 12 hours. The display will appear in the normal
mode with a dark background color for the first 12 hours and will
