Model: HFS-20PRO | Brand: TOOLTOP

1. Introducció

The TOOLTOP HFS-20PRO is a small, highly sensitive radiation dose alarm detector designed for monitoring X, beta (β), and gamma (γ) rays. It utilizes a high-performance semiconductor Geiger counter with energy compensation, offering superior consistency, linearity, and reliability compared to traditional glass or metal counters. This design also mitigates the risk of air leakage failure. The device features a TFT 2.0 color screen for clear display and is easy to operate. It provides both sound and light alarms, with customizable alarm thresholds.

8. Instruccions de funcionament

8.1 Encès/Apagat

  • Per encendre: Long press the "‖" button for 3 seconds.
  • Per apagar: Long press the "‖" button for 3 seconds.

Note: If the "⏰" icon appears at the top of the screen (indicating a scheduled measurement is active), the device cannot be shut down. Enter the "Schedule" page to stop the timing first, then shut down.

8.2 Navigation and Menu Overview

Use the "◀" i "▶" buttons to navigate through menus and adjust values. The "‖" button confirms selections.

8.3 Radiation Measurement

From the main interface, click "Measure" to view real-time radiation data:

  • Taxa de dosi: Instantaneous radiation dose rate (e.g., µSv/h, µR/h).
  • Dose Rate AVG: Average dose rate.
  • CPM: Counts Per Minute.
  • Total Dose: Accumulated radiation dose.

Figure 8.2: Real-time measurement display.

Mode de prova:

  • Lent: Default mode. Includes an internal filtering algorithm to avoid false alarms from external interference. Measurement delay is greater than 5 seconds.
  • Ràpid: For measuring transient X-rays or pulse radiation (e.g., from CT machines). Switch to this mode for quicker response.

8.4 Schedule (Timed Measurements)

This function allows you to set a delayed start and a specific measurement duration.

  1. Enter the "Schedule" menu.
  2. Set the start delay time (00-99 hours, minutes, seconds).
  3. Set the measurement time (00-999 hours).
  4. Click the "‖" button to start.

The device will count down the delay time. Once the delay countdown reaches zero, the instantaneous value, average value, and accumulated dose will be zeroed, and the device will begin counting radiation dose and cumulative dose rate for the set measurement time. At the end of the measurement time, the data is automatically stored in history.

8.5 Records (Historical Data)

The device automatically records data after each timed measurement. It can save up to 100 groups of historical records. When the memory is full, the oldest record will be overwritten by new data.

8.6 Suprimir dades

In this interface, you can delete current or historical data.

  • Delete Current Data: Removes the average dose rate and cumulative time from the radiation measurement page.
  • Delete History Data: Deletes all historical data records.

Note: If the "⏰" icon is on the screen, data deletion cannot be performed. Stop any active scheduled measurements first.

8.7 Configuració d'alarma

The HFS-20PRO features sound and light dual alarms. You can set custom alarm thresholds.

  • Over-limit Alarm Setting Range:
    • Dose Rate: 0.2uSv/h - 999uSv/h (or 20µR/h - 99.9Mr/h)
    • Total Dose: 1uSv - 100000uSv (or 0.1Mr - 10000mR)

When the detected value exceeds the set alarm threshold, the detector will activate both sound and light alarms.

8.8 Unit and Language Settings

In the "Unit" interface, you can switch between measurement units and display languages.

  • Unitats de mesura: Switch between "uSv" and "uR".
  • Idiomes: Canvia entre xinès i anglès.

8.9 Configuració de so

The "Sound" interface allows you to adjust alarm volume and enable/disable count sounds.

  • Volum de l'alarma: Set the desired volume level. Setting to '0' will turn off the alarm sound.
  • Count Sound: Toggle "ON" or "OFF" for the audible click sound during detection.

8.10 Configuració del rellotge

In this interface, you can set the device's internal clock (year-month-day and hour:minute:second).

8.11 Sleep Settings

Configure power-saving options in the "Sleep" interface.

  • Screen Sleep (min): Set the time after which the screen will turn off. Select "to keep screen constant light" for always-on display.
  • Auto Shutdown (hour): Set the time after which the device will automatically power off if inactive.
  • Brillantor de la pantalla: Adjust the screen brightness level (0-10).

8.12 Calibration Factor

The calibration factor can be adjusted for precise measurements. This is an advanced setting.

  1. Premsa "‖" to enter the delete surface.
  2. Double click "Calibration factor" at the bottom of the screen.
  3. A "Password:0000" prompt will appear.
  4. Click the right button "▶" to change the password to "0018" (for calibrating errors 200uSv/h~1uSv/h) or "0020" (for calibrating errors above 200uSv/h).
  5. Feu clic a "‖" to confirm.
  6. Use the left "◀" or right "▶" button to modify the calibration factor.
  7. Finally, click "‖" to save the modified parameter.

Data deletion not possible Scheduled measurement is active. Stop any active scheduled measurements first.

11. Consells d'usuari

  • For general environmental monitoring, the default 'Slow' test mode is usually sufficient and provides more stable readings.
  • If you suspect a sudden, short burst of radiation (e.g., near an X-ray machine), switch to 'Fast' test mode for a quicker response.
  • Regularly check the battery level, especially before critical measurements, to ensure uninterrupted operation.
  • Keep the device's sensitive area (back of the device) clear and unobstructed during measurements for optimal accuracy.
  • Utilize the timed measurement feature for consistent monitoring over specific periods, which can be helpful for trend analysis.
