Diagnostics/Remedy (Continued)
by shorting lead wires in the probe tip. It should be noted that
sudden whipping of the leak detector probe or “blowing” into the
sensor tip will affect the air flow over the sensor and cause the
instrument to alarm.
To identify what area may be the problem you should:
• Remove the protective cap and sensor. Inspect the sensor
leads (these are the small wires coming out the bottom of the
silver can) for straightness. If they are bent , use needle nose
pliers to gently straighten out the wires. Install the sensor and
test the detector.
• If the D-TEK has not been used for 5 weeks or greater, humidity
may have been absorbed by the “core” of the sensor. Turn the
D-TEK on with the sensitivity switch in the HIGH position. Allow
the D-TEK to run for a minimum of 20 minutes or until spiking
alarms stop.
Note:
The absorption of moisture in no way affects
the life or sensitivity of the sensor.
• With the protective cap installed try pushing down on tip of the
probe. Also try bending the probe at the base of the tip from
one side to another. Be cautious not to block the air flow
through the sensor. If you receive a long, continuous alarm,
there may be a short in the probe tip. This failure requires you
to take your leak detector to your wholesaler for handling.
Disposing of Power Cells
At the end of the life of a set of power cells, please dispose of them
according to applicable state and local regulations. In the absence
of such regulations, INFICON encourages its customers to recycle
and/or dispose of the cells through voluntary waste recycling
programs.
