The Advanced tab allows the user to make refinements in how informa-
tion is displayed on the Operating Condition section of the Home screen.
The display contrast level is adjusted using Adjust Contrast Level, with
selections from 1-4. After modifying this parameter, press Save & Exit to
view the brightness and contrast on the Home screen display. Depending
on the lighting and viewing conditions in the final space, different con-
trast levels can improve readability of the SRCM.
Display Averaging (tenths of seconds)
This function is used to improve the stability of the pressure value dis-
played on the Home screen, so significant digits do not change rapidly.
It is used more often in environments where the user requires higher
display resolution (4 digits) but the ambient pressure is unstable. By in-
creasing the number, the effective number of measured data points is in-
creased and a weighted average is developed. Input the number in tenths
of a second for the response time of the display to a pressure change.
There is no ratcheting of the display or a deadband. The pressure change
is very smooth. For example, entering 10 equates to the display reaching
final value in 1 second. Entering 2 equates to final value in 200 ms.
Display Averaging does not affect the Analog Output response time, only
the apparent stability of the pressure display. Display Averaging also
does not affect Alarm Thresholds or Alarm Delay.
What Pressure To Display
This function defines what pressure value is shown on the Home screen
under normal operating conditions. This can be Primary Only, Secondary
Only, or Toggle, depending on what room is most important for visual
pressure verification.
If this is set to Primary Only, then the Home screen will show the pres-
sure value read by the primary pressure transducer (either on-board, or
the alternate primary transducer configured from a separate transducer, if
one is used).
