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 in excess of 1 change per hour every hour for 10 years. If you exceed this number of changes 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
).
First enter the number using the ( / ) and ( ) buttons as above

, 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

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
