Gauge setup
CAUTION
All setups in the TIC are held in non-volatile memory. Non-volatile memory has a limit on the number of times
its content can be changed. Current minimum lifetime is 100,000 changes on a particular section. This equates
to more than 1 change per hour every hour for 10 years. If the number of changes is exceeded, random data
may be stored leading to unexpected system behaviour.
When a new gauge has been identified, scrolling to the selected gauge and pressing the 'Select' (
) button accesses
the 'Gauge Setup' screen. (Refer to
4.8.1
Default setup options (all gauges)
All gauges have the following default items on their respective setup screens. (The example below shows the APGM
as the connected gauge).
Figure 18 - Gauge setup screen
Note:
Active Strain Gauges (ASG) are gas independent. Selection of any gas type will give the same pressure
output.

Description
Gauge
Indicates type of gauge connected.
Gas type
Allows the user to select the gas type.
Choice of: N
2
, He, Ar, CO
2
, Ne, Kr or Volts.
Note:
For gas dependent gauges, it is important that the correct gas is selected to
ensure correct pressure indication.
Filter
Allows the user to select filter status.
Filter 'OFF' gives pressure output as reported by the gauge (update rate 3 per second
approx).
Filter '1 sec' applies a one second moving average to the readings, reducing the effects
of noise on reading stability.
Name
Allows the user to name gauges.
4 characters can be set appropriate to the system, A-Z, 0-9, _ (space).
Note:
If the gauge name is set the name will appear if the gauge is disconnected. To
reset to the gauge type ensure 4 spaces appear in the gauge name setup.
