CHECKING THE TROXALERT
The TroxAlert is powered by a 9-volt alkaline battery. The
battery life is about 2,000 hours under normal operating
conditions.
Always test the battery before using the TroxAlert. To test the
battery, press and hold the top half of the
ON–OFF–BATT
switch. When the switch is pressed, the meter needle should
move into the
BATT
range on the right of the display. If the
needle does not move into this range, then replace the battery.
To access the battery, turn the meter over. Slide the cover on the
bottom of the meter off.
To check the TroxAlert, use any nuclear surface gauge as a
check source. After checking the battery voltage as described
above, turn the meter power on and set the range switch to the
X10
position (change the range as needed). Hold the meter
about 1 foot (0.3 m) away from the gauge and point the meter at
the gauge. Slowly bring the meter closer to where the source rod
meets the gauge top shell. The meter reading [mrem/h (
µ
Sv/h)]
should increase as you approach the gauge. If the needle does
not deflect and there are no changes in the alarm, then the
TroxAlert is not working properly.
In case of an accident that involves a nuclear gauge, notify your
Radiation Safety Officer (RSO) as soon as practical. If the only
available gauge is damaged, then check the TroxAlert battery. If
needed, replace the battery. Assume the TroxAlert is working
properly. Use the TroxAlert to locate the source. If you cannot
locate the source,
immediately
contact your RSO, the licensing
agency, and the gauge manufacturer.
