A typical set-up procedure for the Detec-
tion Mode is:
1. Set up a reference leak which cor-
responds to the smallest leak you
wish to detect.
2. Put the probe close to the reference
leak and note approximately what
reaction you get (no reaction, small,
medium, high, full scale) within the
first few seconds.
3. Set the sensitivity. This can be done
permanently under the menu Detec-
tion Mode Settings or temporarily as
a Direct Sensitivity Adjustment on
the display (unless you have set this
function to OFF under the Detection
Mode Settings menu. See ”Detec-
tion Mode Settings” on p. 23).
NOTE: If the Detection Mode
is used and the alarm function
is required to be activated at a
particular calibrated level, then
the unit must be calibrated in
accordance with the instructions
in ”Calibrate” on p. 21 and
”Calibration” on p. 34. The
reason for this is that the alarm
is based on the Analysis Mode
when the Detection Mode is
displayed, due to inaccuracies in
the Detection Mode signal.
Water protection
The instrument is water-proof, but the
sensor has to be protected if there is a
risk of contact with water or other liquids,
which could penetrate or block the filter
and prevent the tracer gas from reaching
the sensor.
Protect the sensor by placing a piece of te-
flon tape over the filter. Secure it in place
by mounting an Antistatic Sensor Cap.
