5. સેટઅપ

5.1 બેટરી ઇન્સ્ટોલેશન

The HT309 requires product-specific batteries, which are included. Locate the battery compartment on the rear of the main unit. Open the compartment cover, insert the batteries according to the polarity markings (+/-), and close the cover securely.

5.2 પ્રારંભિક પાવર ચાલુ

દબાવો શક્તિ button to turn on the device. The display will illuminate and perform a self-test. Ensure the sensor's protective cap is removed before taking measurements.

6. ઓપરેટિંગ સૂચનાઓ

6.1 Basic Illuminance Measurement (Lux/FC)

1. નો ઉપયોગ કરીને ઉપકરણ ચાલુ કરો શક્તિ બટન
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. ઉપકરણ ચાલુ રાખીને, દબાવો SRC બટન
2. નો ઉપયોગ કરો તીર 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. દબાવો 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.
