Setting up the operating parameters
Screen appearance
( SCREEN APPEARANCE )
The screen display is selectable either to white on black or black on white.
Language selection
( LANGUAGE )
This option is reserved for future extensions, currently only English is available as the operator language. In
coordination with ISM also other languages can be implemented.
Entry of the alarm limit
( ALARM LEVEL )
Here enter the desired limit for the active display operating mode. As soon as this limit is reached, the pointer
instrument of the handset will indicate 100%,
and the “ALARM” LED comes on. Saved measured values
which are above this limit, are clearly marked in the data printout.
The units of measurement in the active display mode are shown as a reminder in the entry area. In order to
change the limit for a different display mode, this display mode will have to be activated first. The instrument
remembers the limits separately for each display mode so that when changing the display mode they will not
have to be entered anew.
It may possibly be required to convert the entered value in consideration of the currently displayed unit of
measurement. The entry may if required, being effected including decimal places.
Threshold for the sound signal during measurements
( WARNING BEGINS AT )
This setting defines the threshold upon which the sound signal as well as the vibration alarm during the
measurements set in. Both set in when the measured value exceeds the limit by the entered percentage.
In the case of the setting NO WARNING, no sound signal nor vibrations are produced during the
measurement. Sound warning signals in the case of error conditions are not affected by this setting.
For leak detection purposes we consider a setting of approximately 20 to 50% as sensible. In practice not
every leak is immediately acquired in full and could be overheard at higher settings.
Vibration alarm on/off
( HAND UNIT VIBRATION )
When this parameter is set to OFF, then the vibration alarm of the handset is disabled.
Display factor 1 analogue gauge in the handset
( DESENS. FACTOR 1 )
Functions only in the measurement mode. Permits pinpointing of larger leaks where full scale of the
analogue gauge is quickly reached. By operating the green SPECIAL button once, the display range is
expanded by the entered factor. In the case of an
active factor of 1, the green “SPECIAL” LED will flash
slowly.
Display factor 2 analogue gauge in the handset
( DESENS. FACTOR 2 )
Functions only in the measurement mode. The display range is expanded by the entered factor by operating
the SPECIAL button twice. With the setting OFF, selection of Desens Factor 2 is disabled. In the case of an
active Factor 2, the green “SPECIAL” LED will flash rapidly
Note: The display factors will only affect the analogue gauge and the sound output, not however, the numeric
display. For this reason also such values can be saved and printed out which have been saved while the
display was in the extended mode.
Selection of the standby operating mode
( STANDBY MODE )
A motion sensor in the handset permits automatic shutting down of the leak detector fully or partially during
operating breaks. When the handset is not moved within a preset period of time, one of the standby
operating modes described in the following is enabled. Running of the standby mode is indicated at the
ha
ndset by a slowly flashing red LED “NOT READY”. When moving the handset again, the instrument will
resume full operation (exception: setting POWER DOWN).
