a piece of glass. Otherwise the reading obtained would be the temperature of the glass.
3.
Steam, dust and smoke could block the infrared from the object being measured and affect the
result of measurement.
4.
When using the infrared thermometer, try to avoid the following:
(1)
static electricity;
(2)
electromagnetic field generated by welding operation or induction heating;
(3)
thermal shock (due to drastic or abrupt cha nges in ambient temperatures, in which case, the
product would need 15 minutes of preparation before being used for temperature measurement.)
(4)
Please keep the thermometer away from the objects with high temperature.
(5)
This is a sophisticated optical device for temperature measurement. Please keep it clear of water
or any corrosive liquid.
5.
If the product is not to be used for a long period of time, please remove the battery to avoid a
battery leak and damage to the product.
IX. How to replace the battery
1.
When the voltage of the battery is below the rated voltage, the Low Voltage Symbol will appear
on the screen. In this case, the voltage is too low for normal operation. Please replace the
battery.
2.
Open the cover of the battery holder and take out the battery. Wait for 3 seconds and then install
the button battery. Make sure the anode and the cathode of the battery are installed at the right
positions.
X. Applications of the infrared thermometer
General Fields of application includes electricity, petrochemicals, metallurgy, automobiles,
electronics, tobacco, pharmaceuticals, hotels, machinery, plastics and moulds. Notably, it could be
used in the following fields:
1.
Industrial electronics: to measure the loose/hot spots of electronic panels, fuse units, engines
/gearboxes, bearings/bearing boxes, power distribution cabinets and electronic components.
2.
Heating or cooling systems: to examine or monitor the status of gas supply, air conditioning or
ventilation pipe systems.
3.
Automobiles: to examine the status o f motors, cylinder heads, heating/cooling systems, or to
scan the temperatures of jammed radiators, power trains, or bearings/bearing shells, etc.
4.
Food safety: to monitor or control food temperature in acceptance, storage, transportation and
production processes, for example in supermarkets (cold storage), hotels and kitchens.
XI. Emissivity
The emissivities of most organic materials and painted/o xidized surfaces are 0.95. Use of the
product on bright or polished surfaces will lead to inaccurate readings. The right way is to cover the
surface with black tape or paint it with black paint. Wait for a period of time sufficient for the black
tape to reach the same temperature as the material covered before measuring the surface
temperature.
