OPERATION
4.3
Gauge identification
When a gauge is connected to the ADC, the display mode will change to display the reading from that gauge. An
identification message consisting of "ID" followed by a number will be displayed for 3 seconds to show that the ADC
has identified the new gauge. The ID numbers and corresponding gauges are shown in
.
If a gauge cannot be identified or is of a type which is not supported by the Controller, then the message "???" will be
displayed.
Where an ASG is used, you need to select the full-scale range of the gauge. This can only be done when the gauge is
first connected. After the identification message "ID15", the display will show 1.0
3
, representing a 1000 mbar ASG.
You can change this to 2.0
3
for a 2000 mbar ASG using the UP and DOWN keys ( / ). When the required value is
showing on the display, press the ENTER key (
).
4.4
Gauge display (standard)
The ADC will continuously display the pressure measured by an Active Gauge. The display is in exponential format.
The pressure units are shown by the LEDs on the right of the display. Use the DOWN key ( ) to change the pressure
units. The units mbar, Torr and Pascal will be selected in turn. A further press of the DOWN key ( ) will select
voltage mode, in which the output voltage of the Active Gauge will be displayed, and the LED enunciators will
extinguish. To return to pressure display, press the DOWN key ( ) again.
If an error condition is detected by the gauge or by the controller, then the display will show an error message of the
form "Err" followed by a number. Refer to
for a list of error numbers and suggested remedies. To clear
the error message from the display press the DOWN key ( ). If the error originated in a gauge it may be necessary
to disconnect the gauge and correct the fault before the error message can be cleared.
If a gauge is not connected then the display will show "- - -".
