4.2 Information on the display
In the measuring mode, the two-digit display shows the currently measured
concentration in % LEL (0 to 99 or 0.0 to 9.9% LEL).
Adjustment and maintenance
If the transmitter enters the calibration or maintenance menu, this is indicated
by a displayed point (bottom right) flashing at approx. 1 Hz.
Faults
Faulty states are indicated by alternatively showing two horizontal lines and the
current error code (E0 through E8).
Turn-on behaviour
All 14 LED segments and both points are activated for 5 seconds directly after
turning on. This is a lamp test to make sure that the LED segments are
functioning. Then, the display shows two horizontal lines and the measured
value for approx. one minute before it switches to measuring mode. During this
time, the calibration and maintenance menu cannot be accessed.
