电器规格

测光学照度公式：

1 lux(勒克司)=1 lumens/m 2 (流明/米 2 )=0.0929 foot-candles(呎烛光)

1 foot-candles (foot-candles)=1 lumens/ft 2 (lumen/foot 2 )=10.764 lux (lux)

Gears: 20lux, 200lux, 2000lux, 20klux, 20fc, 200fc , 2000fc, 20kfc

operating procedures

1. Select the function switch to the required lux (lux) or fc (foot candle)

light) gear (use the "RANGE" switch to select 20lux(fc),

200lux(fc), 2000lux(fc), 20000lux(fc) gears).

2. Take off the protective cover of the illuminance sensor head and put it away.

3. Hold the illuminance sensor head firmly, and make sure that the light source can completely cover the

Cover the cosine correction diffuser plate.

4. Do avoid shadows covering the diffusion plate, the illuminance sensor head has 1.5

The length of the test line in meters can be used for the distance between the observer and the test area

available for application.

5. The reading on the display is the illuminance value to be measured. If you don't know

To measure the illuminance value, you can press the "RANGE" gear key to

the highest gear, and then gradually reduce the gear to get the maximum effective

You can get a very good reading value by changing the number of effective digits.

6. After the measurement, please put the protective cover on the illuminance sensor head to

Prolong the life of the sensor and reduce the aging phenomenon.
