6.1 Basic Illuminance Measurement (Lux/FC)

1. צינדט אָן דעם אַפּאַראַט מיטן הילף מאַכט קנעפּל.
2. Ensure the sensor's protective cap is removed.
3. Place the sensor at the location where you wish to measure illuminance. Ensure the sensor is facing the light source directly.
4. The current illuminance reading will be displayed in Lux.
5. To switch to Foot-Candle (FC) units, press the LUX/FC CD button. Press again to cycle back to Lux or Candela.

6.2 Measuring LED Light Sources

The HT309 can measure illuminance from various LED light sources by applying correction factors.

1. מיטן אפאראט אנגעצונדן, דריק די SRC קנעפּל.
2. ניצן די פייַל buttons to select the appropriate LED light source type (e.g., red, blue, white LED). Refer to the device's display for available options.
3. Once the correct source is selected, the meter will apply the necessary correction factor for accurate measurement.

6.3 Measuring Luminous Intensity (Candela)

To measure luminous intensity, the device requires specific setup and distance from the light source. Refer to advanced measurement techniques for detailed instructions on Candela measurement.

1. דרוק די LUX/FC CD button until "CD" is displayed as the unit.
2. Follow specific instructions in the full manual (if available) regarding distance and light source characteristics for accurate Candela readings.

6.4 Using Hold, Max/Min, and Zero Functions

• HLD (Hold): Press this button to freeze the current reading on the display. Press again to release.
• מאַקס/מין: Press to display the maximum reading recorded since the device was turned on or reset. Press again to display the minimum reading. Press a third time to return to live measurement.
• ZRO (Zero): In a completely dark environment (e.g., with the sensor cap on), press this button to zero the sensor, ensuring accurate low-light measurements.
