Introduction to the working principle of wood moisture meter
Digital lux meters are widely used, mainly used in schools, hospitals, families, offices, factories, hotels, hotels, casinos, shops, department stores, hairdressers, etc.
features
1. Measuring range 1Lux～50,000Lux
2. High accuracy and fast response
3. Reading value locking function, which can lock the measured value
4. Symbol and unit display, easy to read
5. Automatically return to zero
Specification
1. Display: 31/2-digit liquid crystal display, displaying a maximum reading of 1999
2. Measuring range: Lx1010B: 2000.20,000.50,000Lux.
The reading value displayed in the 20,000Lux file needs to be ×10 to be the correct illuminance value The reading value displayed in the 50,000Lux file needs to be ×100 to be the correct illuminance value
3. Accuracy: ±4%rdg±0.5%f.s (accuracy of greater than 10,000Lux is ±5%
±10 characters) (corrected with a standard flat light with a color temperature of 2856K)
4. Repeat test: ±2%
5. Temperature characteristics: ±0.1%/℃
6. Sampling rate: 2.0 times/second
7. Photoreceptor: photodiode with filter lens
8. Operating temperature and humidity: 0℃～40℃(32℉～104℉) 0～70%Rh
9. Storage temperature and humidity: -10℃～50℃(14℉～140℉)0～80%Rh
10. Overload display: the highest digit "1" display
11. Power supply: a single 9V battery
12. Battery life: about 200 hours of continuous use
13. Meter size: 165×57×32mm
14. Weight: 155g
15. Attachment: Instruction Manual
Measurement methods
1. Turn on the power;
2. Select the appropriate measurement gear
3. Open the light detection cover, and align the front of the light detector with the light source to be measured;
4. Read the measured value of the illuminance meter LCD;
5. When reading the measured value, if the highest digit shows "1", it means overload, and you should immediately select a higher gear for measurement;
6. Data hold switch, turn the switch to HOLD, the LCD displays the "H" symbol, and the displayed value is locked, turn the switch to ON, the reading lock function can be canceled;
7. After the measurement work is completed, please cover the light detector and turn off the power of the instrument.
Maintenance
1. Do not measure in high temperature or high temperature places.
2. When in use, the photodetector needs to be kept clean.
3. The light source test reference level is at the top of the light-receiving sphere.
4. The sensitivity of the light detector will be reduced due to the conditions of use or time. It is recommended that you calibrate the meter regularly to maintain the basic accuracy.
