Warning

To avoid electrical shock or personal injury, follow these guidelines:

•

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 thermocouple from the thermometer before opening the case.

•

When the battery mark displays ( ), or you hear a short buzzing sound, please replace the battery

•

immediately.

•

Do not operate the thermometer around explosive gas,
Do not apply more than the rated voltage, as marked on the thermometer, either between the

•

vapor, or dust.

thermocouple, or between any thermocouple and earth ground.

Caution

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

•

Use the proper thermocouples, 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.

Battery power indicator and replacement:

•

The battery power is expressed by five sections of batteries marks. ( )

•

When the battery mark shows ( ) and you hear a short buzzing sound, this indicates the battery
power is weak, please immediately close the unit and replace with 4 AAA batteries to ensure the
measuring reading is accurate.
When battery power is lower than normal operation, this will automatically stop the thermometer

•

operation, and the main display will show BATT and the third display will show LO. Please immediately

.

turn off the unit and replace the 4 AAA batteries.
