6.4.1 Trigger Level 1
 Main menu > Trigger & Alarm s > Trigger Level 1
The value of the first trigger level can be set. See Chapter 4.1.2.7 Numeri-
cal Entries for the description of the entry.
Trigger 1, 2 and Trigger 3 are programmable switching thresholds. When
these thresholds will be exceeded the PhoeniXL reacts as follows:
DisplayIn the status line of the display the signs for Trigger 1, 2 and Trigger 3 are
displayed inverted if the leak rate exceeds (becomes higher than) the pro-
grammed value. (see Fig. 14 &15)
Relay OutputThe trigger-relais of the digital out switches. Please refer to Chapter
2.2.2.2, Digital out, for further details.
Alarm/LoudspeakerAdditionally Trigger level 1 defines at which level the various alarm types
react (See Chapter 6.4.7, Audio alarm type)
6.4.2 Trigger Level 2
 Main menu > Trigger & Alarm s > Trigger Level 2
The value of the second trigger level can be set. Please refer to Chapter
4.1.2.7 Numerical Entries for the description of the entry.
If Trigger 2 is exceeded the corrensponding relay will switch. This is also
indicated at the display (see 6.4.1).
6.4.3 Trigger Level 3
 Main menu > Trigger & Alarm s > Trigger Level 3
The value of the second trigger level can be set. Please refer to Chapter

6.4.4 Units
 Main menu > Trigger & Alarm s > Units
The prefered leak rate unit can be selected. There is the choice of 4 (mbar,
Pa, Torr, atm) pressure units and 5 leak rate units (mbar l/s, Pa m
3
/s,
Torr l/s, atm cc/s, s ft
3
/yr).
In Sniff mode the following measuring units are selectable (Refer to chap-
ter 6.3): ppm, g/a eq (helium leak rate is equivalent with leak rate R134a),
oz/yr eq (helium leak rate is equivalent with leak rate R134a).
