What Is a Digital Light Meter?
Digital illuminance meters are widely used, mainly used in schools, hospitals, homes, offices, factories, hotels, hotels, casinos, shops, department stores, barber shops, etc.
Digital light meter
- 1. Measuring range 1Lux 50,000Lux 2. High accuracy and fast response
- 3.Read value lock function, can lock the measured value
- 4.Symbol and unit display, easy to read
- 5.Auto zero
- 1.Display: 3 1/2 digit LCD display, display maximum reading 1999
- 2. Measurement range: Lx1010B: 2000. 20,000. 50,000 Lux.
- The reading value displayed in the 20,000 Lux file needs × 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% fs (greater than 10,000 Lux file accuracy is ± 5%
- ± 10 words) (corrected with a color temperature of 2856K standard flat light)
- 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 ° C to 40 ° C (32 ° F to 104 ° F) 0 to 70% Rh
- 9. Storage temperature and humidity: -10 ° C to 50 ° C (14 ° F to 140 ° F) 0 to 80% Rh
- 10. Overload display: the highest digit "1" is displayed
- 11. Power supply: single 9V battery
- 12, battery life: about 200 hours of continuous use
- 13. Electric meter size: 165 × 57 × 32mm
- 14. Weight: 155g
- 15. Attachment: instruction manual
- 1. Light detector: for light detection;
- 2. LCD Monitor;
- 3 Gear selection switch: 2000, 20000, 50000 Lux can be selected;
- 4 Power on, off, and reading hold;
- 1. Turn on the power;
- 2. Choose the right measurement gear
- 3 Open the light detection cover and point the front of the light detector at the light source to be measured;
- 4 Read the measured value of the illumination meter LCD;
- 5. When reading the measured value, if the highest digit shows "1", it means overload, and the higher gear should be selected for measurement immediately;
- 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 to cancel the reading lock function;
- 7. After the measurement is completed, cover the photodetector and turn off the power of the instrument.
- 1. When the battery power is low, an "" indicator appears on the LCD, indicating that the battery must be replaced.
- 2. Turn off the power, remove the screws, open the battery door, remove the battery from the battery buckle, and replace it with a new 9V battery.
- 3. Close the battery door and tighten the screws.
- 1. Do not measure in high temperature or high temperature places.
- 2. The photodetector should be kept clean during use.
- 3 The light source test reference level is at the top of the light receiving sphere.
- 4 The sensitivity of the photodetector will decrease due to the use conditions or time. It is recommended that you periodically calibrate the meter to maintain basic accuracy.
