Battery replacement
1.The symbol " " that appears in the upper left
of the LCD display indicates that the unit's
battery is running low. Please replace the 1.5V
battery at once to ensure the test accuracy.
2.Remove the battery cover by one screwdriver.
3.Replace the old battery with four new 1.5V
batteries and lock the battery cover.
4.Prior to replacing the battery, please make
certain to remove the thermocouple from the
temperature gauge as a safety precaution.
5.When in extended idle, please remove the 1.5V
battery from the temperature gauge and store
the temperature gauge only in a cool and low-
humidity setting.
6.To avoid combustion, DO NOT dispose of
batteries in general into an open flame.
7.Caution the positive and negative polarity when
loading battery.
8.Please abide by pertinent laws and regulations
when disposing of used batteries.

Caution
1.Input protection: The temperature jack carried
a maximum voltage of 24 volts DC or AC .
2.Temperature jacks: Design for the insertion of a
standard small thermocouple jacks, which has a
center spacing of 7.9mm between the two
prongs.
3.Please DO NOT placed inside a microwave for
temperature testing.
4.A correct thermocouple slot should be chosen
when operating the temperature gauge.
5.Please DO NOT attempt to use a temperature
gauge that is not working properly, for this may
result in physical harms, send for repair service
at once.
6.Please DO NOT attempt to operate the
temperature gauge in the around sites where
explosive gases, vapor or dust particles are
present.
7.Please refrain from subject the paired
thermocouple or the grounding between the
thermocouples to a voltage exceeding what has
been marked on the unit.
8.When gauge occur crashed , please take one
battery out for above one minute. Then place
the battery back and restart the gauge.
