displayed inverted if the leak rate exceeds (becomes higher than) the pro-
grammed value. (see Fig. 14 &15)
Relay Output
The trigger-relais of the digital out switches. Please refer to Chapter
2.2.2.2
, Digital out, for further details.

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).
