1. Introduction
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 Overview
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.

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. Operating Instructions
6.1 General Functions (Both Devices)
- MAX/MIN Recording: Press the 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.
- Data Hold: Press the HOLD button (or similar icon) to freeze the current reading on the display. Press again to release.
- Backlight: Press the Backlight button (often marked with a light bulb symbol) to activate or deactivate the screen backlight for improved visibility in low-light conditions.

6.2 TS-501B Sound Level Meter Operation
- Turn on the device.
- Select Weighting (A/C): Press the A/C button to switch between A-weighting (for human ear perception) and C-weighting (for general noise analysis).
- Select Response Time (FAST/SLOW): Press the F/S 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
- Turn on the device.
- Rotate Sensor: Adjust the 180° rotating sensor to face the light source directly or to capture ambient light as needed.
- Select Unit (LUX/FC): Press the UNIT button to switch between Lux and Foot-Candle measurement units.
- The device will display the light intensity, ambient temperature, and humidity.
7. Maintenance
- Cleaning: 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.
- Storage: 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.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display to ensure continuous accurate operation.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead batteries; incorrect battery polarity. | Replace batteries with new ones; ensure correct polarity. |
| Inaccurate readings. | Sensor obstruction (TS-710); microphone obstruction (TS-501B); environmental interference. | Clean the sensor/microphone; ensure no obstructions; re-measure in a stable environment. |
| Display is dim or blank. | Low battery; backlight off. | 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). |
