Q:
Will the Prowler alarm when entering a work area contaminated with
refrigerant?
A:
Yes. Nevertheless, you must always turn on the Prowler outside of the
work area (in clean air) and allow it to complete the warm up cycle before
entering an area where a large leak is suspected. The Prowler will alarm
initially but will automatically self calibrate to the surroundings and will not
alarm again until a larger concentration closer to the source of the leak is
detected.
Q:
Why does the alarm stop sounding when the sensor is held static at a
leak source?
A:
This is normal and demonstrates how the detector automatically resets
(self calibrates) itself to the ambient. Once the Prowler alarms near the
area of the leak, it should be moved away from the leak and back again to
verify the exact location and size of the leak. If the leak is large (more than
fi
ve bars), it may be necessary to move the sensor away from the leak
area for 5 to 10 seconds
Q:
Can the Prowler determine the size of the leak?
A:
Yes, once the leak has been pin pointed the maximum number of bars
on the LCD screen will give the user an idea of the size of the leak. If the
leak is large, (5 bars or more) it may be necessary to hold the detector
away from the leak for 5 to 10 seconds in order for the circuit to reset com-
pletely and to give an accurate indication of the leak size.
Q:
What does the Prowler do when it is turned on and is going through the
warm up mode?
A:
When turned on, the Prowler begins to energize and condition the
sensor for use. During this period, the unit will beep at a slow rate and the
LCD bar graph will display the conditioning progress by gradually increas-
ing. Warm up is complete when all 10 bars are shown on the display. The
beep rate will also increase and the sensitivity level will default to Medium.
Note: The bars on the bar graph may increase up initially and then down
again before increasing to 10 full bars. This is normal.
Q:
How should the Prowler be tested to make sure it is working properly
prior to leak searching?
A:
The preferred method to test the Prowler is with the Leak Test Vial that
is included with the leak detector. Although the Vial does not contain re-
frigerant gas or liquid (this is prohibited), the media in the Vial accurately
simulates a small to medium refrigerant gas leak. To test with the Vial,
power on the Prowler by depressing the on/off button. Allow the instrument
time (up to 20 seconds) to energize the sensor. Remove the plastic label
seal on the top of the Leak Test Vile and place the sensor closer to the
small hole in the top of the Vile. The beep rate should increase and the
