1. Timer hold function
Retain the measured value after a user-configured amount of time has elapsed from the time the TIMER key is pressed. In this way, you can time measurement to occur after you have moved away from the lux meter so that measurement is not affected by clothing, shadows, etc.
Timer settings:
Select from 5 / 10 / 15 / 20 / 30 / 45 / 60 sec.
After the set time has elapsed, the measured value is retained. → The backlight turns on and the beep sounds for 3 sec.
2. Measurement with sensor and display units undocked
You can undock the display and sensor units for more convenient use. Simply connect them with the Connection Cable L9820 (option).
20 lx range measurement resolution 0.01 lx
1. Memory function (up to 99 values)
Save measured values for multiple measurement locations in the instrument’s internal memory on the spot for later display at your convenience. There’s no need to take time to jot down a reading on paper for each measurement.
2. Data communications functionality
Transfer data saved in the instrument’s internal memory to a computer via a USB connection. Data can be saved as a text file.
