How does the thermometer measure small targets?
aiming and focusing
Aiming: The small black dot in the eyepiece is the temperature measurement point, use the black dot to aim at the measured target
Focusing: Move the objective lens back and forth until the measured object is clearly visible. If the diameter of the measured object is much larger than the small black dot, it is not necessary to perform full focus adjustment. Please refer to the instruction manual for the specific method of focusing. When measuring a small target, for the accuracy of the measurement
⑴ The thermometer should be fixed on the tripod (optional accessory)
⑵ Need to focus, that is: use the small black dots in the eyepiece to aim at the target (the target should be full of small black dots), adjust the lens back and forth, shake the eyes slightly, if there is no relative movement between the measured small black dots, then focus it's done
How to measure temperature with infrared thermometer?
In order to measure the temperature of the infrared thermometer, point the infrared thermometer at the object to be measured, press the trigger to read the temperature data on the LCD of the instrument, and ensure that the ratio of the distance to the spot size and the field of view are arranged. There are a few important things to remember when using an infrared thermometer:
1. Only the surface temperature is measured, and the infrared thermometer cannot measure the internal temperature.
2. The temperature cannot be measured through the glass. The glass has very special reflection and transmission characteristics, and the infrared temperature reading is not allowed. But the temperature can be measured through the infrared window. Infrared thermometers are best not used for temperature measurement on shiny or polished metal surfaces (stainless steel, aluminum, etc.).
3. Locate the hot spot. To find the hot spot, the instrument aims at the target, and then scans up and down on the target until the hot spot is determined.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects the temperature measurement.
5. Ambient temperature. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
