Before using the thermometer inspect the case. Do not use the thermometer if it appears damaged.
Look for cracks or missing plastic. Pay particular attention to the insulation around the connectors.

•

Disconnect the RTD from the thermometer before opening the case.

•

When displays battery mark become ( ), and you hear a short buzzing sound,
replace the battery immediately, the possibility of false readings can lead to personal injury.

•

D

o not use the thermometer if it operates abnormally. Protection may be impaired. When in doubt,

have the thermometer serviced.

•

Do not operate the thermometer around explosive gas, vapor, or dust.

•

Do not exert the voltage to RTD or earth.

•

Do not take RTD direct measure generator set or equipment, intense electric shock possibly can
lead to personal injury.

•

Wh

en the thermometer cover opened, is sure not to use thermometer.

•

Do not to put thermometer in the microwave oven to measure temperature.
When RTD measure is high temperature or low temperature, you should be careful to avoid goods

•

because it can can lead to personal injury.

Caution

A caution identifies conditions and actions that may damage the meter or the equipment under test.

Use the proper RTD, function, and range for your thermometer.

•

Do not attempt to recharge the batteries.

•

To prevent explosion, do not throw batteries into a fire.

•

Follow local laws or regulations when disposing of batteries.

•

Match the + and - polarities of the battery with the battery case.
