HT HT309

HT-Instruments Multi LED Lux Meter HT309 User Manual

Model: HT309

1. Introducció

The HT309 is a digital light meter designed for precise measurement of illuminance. It utilizes a silicon photodiode sensor to measure light levels up to 400,000 Lux. This device is specifically capable of measuring illuminance from LED sources of various colors by applying relevant correction factors, and it can also measure luminous intensity, expressed in Candela.

This manual provides comprehensive instructions for the safe and effective use, setup, operation, and maintenance of your HT-Instruments HT309 Lux Meter.

5. Configuració

5.1 Instal·lació de la bateria

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 Encès inicial

Premeu el botó Poder 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. Instruccions de funcionament

6.1 Basic Illuminance Measurement (Lux/FC)

  1. Turn on the device using the Poder botó.
  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. With the device on, press the SRC botó.
  2. Utilitza el Fletxa 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. Premeu el botó 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.
  • MÀXIM / MÍN: 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.

7. Manteniment

7.1 Neteja

Wipe the device and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor surface is clean and free of dust or smudges for accurate readings.

7.2 Emmagatzematge

When not in use, store the HT309 in its carry case in a cool, dry place, away from direct sunlight and extreme temperatures. Always place the protective cap on the sensor before storage.

7.3 Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries promptly to ensure continued accurate operation. Refer to section 5.1 for battery installation instructions.

8. Solució De Problemes

Problema Causa possible Solució
El dispositiu no s’encén. Piles gastades o instal·lades incorrectament. Comproveu la polaritat de la bateria o substituïu les bateries.
Lectures inexactes. Dirty sensor; incorrect light source setting; sensor cap on. Clean sensor; verify light source setting with SRC button; remove sensor cap. Perform ZRO calibration in darkness.
La pantalla mostra "OL" (sobrecàrrega). Light intensity exceeds measurement range. Move the sensor to an area with lower light intensity.
