Measurement methods

1. Set the upper limit of the instrument alarm: Press and hold the Mode key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the alarm upper limit setting, in this case, Hi is displayed in the instrument function indication zone, and the alarm upper limit value is displayed in the zone, the value blink. Press / the key to increase or decrease the alarm value, and long press the / key to accelerate the increase or decrease of the set value.

2. Set the low alarm value of the instrument Press and hold the Mode key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the alarm lower limit setting, in this case, Low is displayed in the instrument function indication zone, and the alarm lower limit value is displayed in the zone, the value blink. Press / key to increase or decrease the alarm value, and long press  / key to accelerate the increase or decrease of the set value.

3. Set the instrument radiance Press and hold the Mode key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the instrument radiance setting, in this case, the instrument radiance indication zone flashes. Press the / key to increase or decrease the radiation value, and long press the / key to accelerating the increase or decrease of the set value.

4. Set the instrument temperature unit Press and hold the MODE key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the instrument temperature measurement unit, the unit symbol on the display flashes, and press the / key to change the unit symbol.

5. Exit the setting
   Press the trigger or long-press the MODE key, to exit the instrument setting.

6. Turn on/off laser Press the Mode Button to turn on or off the Laser, and the instrument will display the laser symbol

7. Non-contact temperature measurement
   Aim the thermodetecto at the object, and hold the trigger, to conduct continuous measurement of temperature. After displaying stably, release the trigger, and the measurement result will be maintained.

When holding the trigger, the secondary display of the instrument will display the maximum value of the measured temperature.

When the measured value is greater than the upper limit of the high alarm or the measured value is less than the lower limit of the low alarm, the red alarm indicator will turn on to the alarm.

Target distance ratio (D:S ratio)

The thermodetector has a certain visual angle and visual field, as shown in the following figure.

In order to guarantee the measured object fills in the visual field of the thermodetector, which means the thermodetector only “sees” the measured object rather than other objects. Larger objects may cause larger temperature measurement distances; for smaller objects, the measurement distances must be close. The ratio of measurement distance to the measured target (D:S) is 12:1, as shown in the following figure:

Radiance

The radiance characterizes the ability of an object to radiate infrared rays. Larger radiance will lead to stronger radiation ability on the object’s surface.

The radiance of the majority of organic matter or metal-oxidized surfaces ranges between 0.85 and 0.98. The radiance of the thermodetector is 0.95 by default. During measurement, set the radiance of the instrument the same as the radiance of the measured object. During measurement, please pay attention to the impact of emissivity on measurement results. The following table is the radiance reference table.
