Medical Infrared Thermometer Non Contact Celsius / Fahrenheit Mode Selectable

Instructions

1) Power on
2) Point the infrared detector part to the center of the forehead—above the center of the eyebrow and keep it

vertical. The measurement area must not be covered by hair. If there is sweat, it should be dried.
3) The body temperature is displayed on the screen, the value is recorded, and the temperature measurement is

completed.

Precautions:

1. Please read the instructions carefully before measuring, and the forehead should be kept dry and the hair should

not cover the forehead. (Please measure in the environment of 10 ℃ -40 ℃) to ensure the accuracy of the

measurement.
2. The forehead temperature quickly measured by this product is for reference only and should not be used as a

basis for medical judgment. If abnormal temperature is found, please use a medical thermometer for further

measurement.
3. Please protect the sensor lens and clean it in time. If the temperature change during use is too large, it is

necessary to place the measuring device in the environment to be measured for 20 minutes, and then use it after it

has stably adapted to the ambient temperature, and then a more accurate value can be measured.

Note

A warning describes actions that may cause a hazardous situation to the user. To avoid electric shock or personal

injury, follow these guidelines:
Do not aim the laser directly at your eyes or indirectly reflected surfaces. Before using the thermometer, check

the case. If the thermometer is damaged, do not use it. Look for damage or missing plastic parts. Replace the

battery as soon as the battery indicator "" appears. Do not use the thermometer if it is malfunctioning. Instrument

protection may have been compromised. If in doubt, send the thermometer for repair. Do not use the thermometer near

explosive gases, vapors or dust. To avoid the risk of burns, keep in mind that objects with high reflectivity will

often make temperature measurements lower than the actual temperature of the object. If this equipment is used in a

manner not specified in this manual, the protection provided by the equipment may be impaired.

To avoid damaging the thermometer or device under test, protect them from the following injuries:
From EMF (electromagnetic field) including electric welding machines, electric induction heaters, static

electricity, thermal shock (caused by large or sudden ambient temperature changes-wait 30 minutes to stabilize the

thermometer before use). Do not leave the thermometer on or near hot objects. Various symbols and safety signs on

the thermometer and in the manual.
