1. Inleiding
This manual provides essential information for the safe and effective operation of your TopTes TS-501B Sound Level Meter and TS-710 Light Meter. These devices are designed for accurate environmental monitoring, allowing users to measure noise levels and light intensity in various settings. Please read this manual thoroughly before use and retain it for future reference.
2. Product voorbijview
The TopTes TS-501B Sound Level Meter and TS-710 Light Meter are a combined solution for environmental assessment. The TS-501B measures sound levels, while the TS-710 measures light intensity, ambient temperature, and humidity. Both devices feature a 2.25-inch backlit LCD screen for clear readings and user-friendly functions.
2.1 TS-501B Sound Level Meter
The TS-501B is equipped with a 1/2 inch electric condenser microphone for precise sound measurement. It offers A/C weighting options to analyze sound based on human ear perception (A-weighting) or for general noise analysis (C-weighting). The measurement range is 30 to 130 dB.

Figuur 1: TS-501B Sound Level Meter showing A-Weighting measurement. This mode measures sound levels as perceived by the human ear, typically ranging from 30 to 130 dBA.

Figuur 2: TS-501B Sound Level Meter showing C-Weighting measurement. This mode is suitable for general noise analysis, with a range of 30 to 130 dBC.

2.2 TS-710 Light Meter
The TS-710 features a 180° rotating sensor for flexible light measurement from various directions. It measures light intensity from 0.1 to 200,000 lux (or 0.1 to 20,000 FC) and also provides readings for ambient temperature and humidity.

6. Gebruiksaanwijzing
6.1 General Functions (Both Devices)
- MAX/MIN Recording: Druk op de MAX/MIN button to display the maximum or minimum recorded value during a measurement session. Press again to cycle through MAX, MIN, and current readings.
- Gegevensopslag: Druk op de UITSTEL button (or similar icon) to freeze the current reading on the display. Press again to release.
- Achtergrondverlichting: Druk op de Achtergrondverlichting button (often marked with a light bulb symbol) to activate or deactivate the screen backlight for improved visibility in low-light conditions.

Figuur 7: Explanation of MAX and MIN functions. MAX displays the highest value measured, while MIN displays the lowest value measured over a given period.
6.2 TS-501B Sound Level Meter Operation
- Zet het apparaat aan.
- Select Weighting (A/C): Druk op de Airconditioning button to switch between A-weighting (for human ear perception) and C-weighting (for general noise analysis).
- Select Response Time (FAST/SLOW): Druk op de V/V button to choose between Fast (125ms) or Slow (1s) response times, depending on the nature of the sound being measured.
- Point the microphone towards the sound source. The current sound level in decibels (dB) will be displayed.
6.3 TS-710 Light Meter Operation
- Zet het apparaat aan.
- Rotate Sensor: Adjust the 180° rotating sensor to face the light source directly or to capture ambient light as needed.
- Select Unit (LUX/FC): Druk op de EENHEID button to switch between Lux and Foot-Candle measurement units.
- The device will display the light intensity, ambient temperature, and humidity.
7. Onderhoud
- Schoonmaak: Use a soft, dry cloth to clean the device surfaces. Do not use abrasive cleaners or solvents. For the TS-710's light sensor, ensure it remains clean and free of dust for accurate readings.
- Opslag: Store the devices in their protective carrying cases in a cool, dry place when not in use. Avoid areas with high humidity or extreme temperatures.
- Batterij vervangen: Replace batteries promptly when the low battery indicator appears on the display to ensure continuous accurate operation.
8. Probleemoplossing
| Probleem | Mogelijke oorzaak | Oplossing |
|---|---|---|
| Apparaat gaat niet aan. | Lege batterijen; verkeerde polariteit van de batterijen. | Vervang de batterijen door nieuwe; let op de juiste polariteit. |
| Onnauwkeurige metingen. | Sensor obstruction (TS-710); microphone obstruction (TS-501B); environmental interference. | Clean the sensor/microphone; ensure no obstructions; re-measure in a stable environment. |
| Het scherm is donker of leeg. | Batterij bijna leeg; achtergrondverlichting uit. | Replace batteries; press the backlight button. |
| Automatic power-off occurs too quickly. | Default auto-off setting. | This is a feature to conserve battery. Refer to specific device settings if adjustable (not all models allow adjustment). |
