3.2 How to Use the Compur Ex plus

After switching on the Compur Ex plus detector, the instrument will show for approx. 20 seconds the software version (i.e. –1.1-) on the display. During this time the sensor will reach its working temperature.

3.3.1 Selftest

When switching the Compur Ex plus into the “TEST”- position, it will perform an automatic selftest. This test checks the following functions:

??LED

? flashes

??Buzzer

? alarm sounds

??Display

? all LCD elements start flashing

??Battery voltage

? If remaining battery voltage is below the preset value,

 

the instrument will show the battery prealarm. In this event the

 

detector will work for at least another 30 minutes.

If you leave the switch in the “TEST”- position after the selftest, LED and buzzer will alarm at certain intervals.

3.3.2 Measuring Mode

After the selftest with the functions switch in the “ON”- position, the Compur Ex plus is in the measuring mode. After a few seconds the actual gas concentration will be shown on the display.

3.3.3 Alarms

The actual gas concentration is continously compared with the preset alarm levels A1 and A2. Standard factory setting is 25 % and 50 % LEL. When exceeding the alarm levels, the detector will generate an optical and acoustic alarm.

If the concentration is above the first alarm level (A1), the buzzer can be switched off with the reset button. The red LED will continuously flash. It is not possible to reset the main alarm (A2). Both alarms are not latching. If the actual value is below the set thresholds, the alarm will stop.

If 100 % LEL is exceeded, the display starts flashing and shows. 100 %. If the gas concentration comes back below the 100 % LEL level, the display will show the actual concentration but will still be in the flashing mode. The optical and acoustic alarms will stay activated until the Compur Ex plus is switched off.
