8.2 Field of View
When measuring, make sure that the measured target is larger than the
light spot diameter. The smaller the target, the closer the test distance should
be (refer to D: S for the detailed light spot diameter). It is recommended
that the measured target be larger than twice the light spot diameter of the
thermometer.
8.3 Emissivity
Emissivity represents the ability of the measured object to emit infrared
energy. Infrared measurement is to measure the infrared energy to determine
the temperature. Objects of different materials have different emissivity.
The default emissivity of A63 2in1 food thermometer is 0.95. The emissivity
is best for measuring the temperature of food (hot, frozen, refrigerated food
or food in plastic containers), water, oil, sludge, paint, ceramics, rubber and
paper.
9. Maintenance and Cleaning
The ingress protection rating of A63 2in1 food thermometer is lP65. The
shell and probe can be cleaned with a moist sponge or soft cloth or
sprayed with a moderate amount of detergent under running water.
Please dry the product after cleaning.
Use a cotton swab soaked in water or medical alcohol to clean the surface
of the lens.

Replace batteries
Restart the product or reinstall the
batteries and then restart it. If the
product still does not operate
normally, repair it.
Refer to Field of View, D:S and
other instructions in this manual.
Repair the probe if it is damaged.
11. Notice for Use
The infrared mode measures the surface temperature, and the probe mode
measures the internal temperature of food.
Infrared measurement:
If the ambient temperature changes (e.g., from indoor to outdoor), the
thermometer should be allowed at least 30 minutes to stabilize,
otherwise error may be caused.
If there is dust or foreign matter on the lens of the infrared sensor, clean
the lens according to the method (9. Maintenance and Cleaning) and
continue to measure after the lens surface is dry.
Make sure there are no other obstacles between the product and the
measured object.
For vacuum packed food, please do not measure the package.
Probe measurement:
The probe has a minimum penetration depth of 12.7mm.
Do not use the product in corrosive acids or alkalis.
