exceeded. Below the trigger level the loudspeaker will remain off.
TRIGGER
ALARM
An acoustic alarm with a continuous low tone will sound as soon as
the search level is exceeded. An acoustic alarm which consists of
two tones sounds as soon as the trigger level is exceeded. Below the
search level the loudspeaker will remain off.
If the Protec P3000 is set to TRIGGER ALARM as the alarm type an
additional button will be shown on the lower right side called TONE
1,2,3. With this button different alarm sounds can be selected for the
trigger alarm to clearly distinguish between nearby other leak
detectors.
PINPOINT The external loudspeaker is always on. Within the leak rate range of
+/- one decade of the trigger level the frequency will change
depending on the leak rate. Outside this range the tone will be
constantly low or high. This setting is recommended if also leaks
which are still below the trigger level need to be pinpointed or if the
expected leak rates are within the range of the trigger level.
