Tracer TP-9360 PRO-Alert M-L AM06026-3 - Manual (Page 5)

2. Slowly (approximately 1 to 2 inches/second [25 to 50 mm/second]) move the probe
past each possible leakage point.
NOTE: It is important to move the tip of the probe past the leak. If held on a leak, the
auto-zero feature will gradually zero out the leak signal.
3. When the instrument detects a leak, it will emit a different tone and the LED flash
rate will increase to signal the leak.
4. When the PRO-Alert™ signals a leak, pull the probe away from the leak for a
moment, then bring it back to pinpoint the location.If the leak is large, set the
sensitivity switch to LOW, by quickly pressing the main control button, to make it
easier to find the exact site of the leak.
5. Return the sensitivity switch to HIGH before searching for additional leaks.
6. When you have finished leak testing, turn OFF the instrument and store it in a clean
place, protected from possible damage.
How to Change the Filter
The foam filter at the probe tip should be replaced if it becomes plugged with water or oil.
To replace the filter, simply pull out the old filter (with a paper clip or similar device). Then,
push in the new filter.
Cleaning the PRO-Alert™ Housing
The PRO-Alert™ plastic housing can be cleaned with standard household detergent or
isopropyl alcohol. Care should be taken to prevent the cleaner from entering the
instrument. Since gasoline and other solvents may damage the plastic, protect your
PRO-Alert™ from contact with these substances.
Disposing of the Alkaline Batteries
At the end of the life of a set of alkaline batteries, please dispose of them according to
applicable state and local regulations. In the absence of such regulations, Spectronics
encourages its customers to recycle and/or dispose of the cells through voluntary waste
recycling programs.
