Verification Of Operation; Simulation Of Gas Levels - AMC -UT M-400 Series User Manual

6.4 VERIFICATION OF OPERATION

Verification of operation should be performed at least once every 6 months. For highly demanding
applications more frequent verification is recommended.

6.4.1 SIMULATION OF GAS LEVELS

The UTx-M Sensor Service Menu allows the current gas reading to be overridden by a
simulated gas level. This may be useful during system configuration to verify operation of the
Digital Monitor or alarm relays.
If 'Override' is activated from the sensor's service menu, then the display will be updated to show
the following sub-menu.
If 'Sim Enable' is activated from the 'Override' sub-menu, then the display will be updated to show
the following editing screen.
When the ENTER button is pressed, the confirmation screen (described previously) is displayed.
If Yes is selected, the edit value is persisted as the new value for the Sim Enable Flag. Otherwise,
the edit value is rejected. In either case, the menu returns to the Override sub-menu menu with
the 'Sim Enable' menu item selected.
If 'Sim Gas' is activated from the 'Override' sub-menu, then the display will be updated to show
the following editing screen.
