Battery
Warning
The battery is a safety device. Do not attempt to disassemble or alter the battery. Always observe the
following precautions:
•
Do not short-circuit the battery by directly connecting the negative terminals with positive
terminal.
•
Do not heat the battery or discard it in a fire.
•
Do not expose the battery to temperatures over 50°C (122°F). Keep the battery away from fire
and other heat sources.
•
Do not charge the battery near a heat source, such as, a fire or heater.
•
Do not leave the battery in direct sunlight.
•
Do not pierce the battery with a sharp object, hit or step on it.
•
Do not use a damaged battery.
•
Do not apply solder to a battery.
•
Do not connect the battery to an electrical power outlet.
To prevent the battery bursting, igniting, or fumes from the battery causing equipment damage,
always observe the following precautions:
•
Do not immerse the battery in water or allow it to get wet.
•
Do not place the battery in a microwave oven or pressurized container.
•
If the battery leaks or emits an odor, remove it from all possible flammable sources.
•
If the battery emits an odor or heat, is deformed or discolored, or in a way appears abnormal
during use, recharging or storage, immediately remove and stop using it.
Instrument
•
If the unit is exposed to significant changes in ambient temperature (hot to cold or cold to
hot), allow 30 minutes for temperature stabilization before taking measurements.
•
Do not operate the unit near large electrical or magnetic fields such as arc welders and
induction heaters. These fields can cause measurement errors.
•
For the short wavelength units (e.g., 1.0 µm and 1.6 µm) — avoid taking temperature
measurements in bright sunlight. High levels of ambient light may produce apparently valid
high-temperature readings when no target is in the thermometer’s field-of-view.
