Leak detector operating steps
1
Insert the suction probe into the probe receptacle on the top
of the unit (see
). If desired, a length of inert tubing
can be substituted for the included sampling probe using the
brass hose barb supplied with the probe
.
2
Turn the unit on and press
MODE
three times to cycle to
Leak mode. The word “Leak” will appear in the mode
indicator position on the display. Allow the detector to warm
up until the “WarmUp” indicator in the display disappears
(approximately 7—8 minutes). The suction pump will power
up (usually heard as a faint squeaking sound) when the
device is ready to make gross leak measurements.
3
Ensure that the device is well away from the suspected leak
area. Press
ZERO
.
It is good practice to allow the detector to purge away from
the suspected leak for 1—2 minutes between leak detections.
4
Press
GAS
to select the gas to be detected.
If desired, the sound can be toggled on at this point by
pressing the
SOUND
button. Normal, no leakage conditions
are indicated by slow intermittent ticks. As the conductivity
varies from that of air when leaks are detected, the tick
frequency and pitch become proportionately higher.
N O T E
In Leak mode, the ZERO button is used to store the conductivity of ambient
air away from a potential leak. This value is used to calculate relative
conductivity and inferred leak rate.
N O T E
The detector will use the conductivity of the selected gas, along with the
conductivity detected and the constant flow rate to infer a leakage rate. If
the selected gas happens to be an undetectable gas (as denoted in
), the rate, conductivity, and relative conductivity parameter
indicators will read “gas?” to prompt the user to select a detectable gas.
