5.2.2 Simulating the detector
Navigation:
Service menu
A gas-detection simulation can be conducted without disconnecting a detector that is
connected to a measurement channel on the U•H1 unit.
The simulation starts with:
▪
The initial value for the simulation is the actual gas concentration read by the
detector.
▪
The cursor flashes on the digit being modified (tens or units).
The user can modify the simulated gas-concentration value using the Up and Down arrow
keys.
The user can use the Right and Left arrow keys to move from one digit of the gas-
concentration value to the other, with the first digit changing the tens and the second digit
changing the units.
The user can end the simulation by pressing ESC.
Alarm management operates as per usual during a simulation. This means that, if the
simulated gas concentration exceeds an alarm threshold, the alarm is triggered and the
associated outputs are activated, along with the servos connected to them.

5.3.1 Initializing the detector
Navigation:
Service menu
The factory settings of the U•H1 unit disable all the measuring channel. The U•H1 unit then
needs to be told if the detector is connected.
Detection and calibration phase
▪
A rotating symbol shows the progress of the calibration.
▪
A "-" (hyphen) symbol indicates a channel that does not have a detector or a channel
that is connected to a detector for which the zero-calibration failed (too much signal
interference).
▪
A "*" (asterisk) symbol indicates a channel that is connected to a detector that has
been zero calibrated successfully.
The result of the detection is displayed:
