1. Introduction and Overview
The HFS-20PRO is a portable personal radiation dosimeter designed for detecting X, γ, and β rays. It offers high detection sensitivity, making it ideal for environmental radioactivity monitoring and identifying traces of nuclear radiation. This device features a TFT 2.0 color screen for real-time data display, dual sound and light alarms, and data storage capabilities.
Understanding radiation is crucial for safety. Nuclear radiation can pose various health risks, including cataract, lung problems, leukemia, alopecia, skin disease, and thyroid problems. The HFS-20PRO helps monitor radiation levels in various environments.
Its wide application range includes family life, radiology departments, industrial radiation monitoring, and food radiation detection.
2. Features
- High Detection Sensitivity: Especially effective for environmental radioactivity monitoring and detecting trace nuclear radiation.
- TFT 2.0 Color Screen: Provides real-time display of instantaneous, average, and accumulated radiation values.
- Ray Detection: Measures X, γ, and β rays, with high sensitivity for common nuclides.
- Real-time & Cumulative Dose: Measures dose rate in real-time and records cumulative dose, with a calibration function.
- Dual Alarm System: Features both sound and flash alarms. Dose rate and metering alarm thresholds are continuously adjustable.
- Timed Measurements: Allows setting a start-delay time (00-99h) and measurement time (00-999h). Automatically stores interval measurement data in history.
- Historical Data Storage: Saves information for the last 10 measurements.
- Calendar Clock Function: The clock runs normally even when powered off, supporting year-month-day and hour-minute-second settings.
- Battery Level Monitoring: Continuous display of battery level icon.
- Multifunctional Design: Supports Chinese and English language switching and measurement unit switching.
- Sensor Failure Indication: Displays "device damaged" if a sensor issue occurs.
- Automatic Alarm Jump: If the radiation dose exceeds the set alarm value, the monitor automatically alarms and jumps to the radiation measurement page.
- Data Deletion: Allows deletion of current data (resets average value and accumulated time) and historical data (clears all history).
3. Package Contents
Upon opening the package, please verify that all items listed below are present and in good condition:
- 1 x HFS-20PRO Nuclear Radiation Detector
- 1 x USB Type-C Charging Cable
- 1 x Wrist Strap
- 1 x Operation Manual (this document)
4. Setup
4.1 Initial Charging
Before first use, fully charge the device. Connect the supplied USB Type-C cable to the charging port on the device and to a standard USB power source (e.g., computer, wall adapter). The green light on the device will remain on during charging and turn off once fully charged.
4.2 Power On/Off
Locate the 'On, off and selection key' (typically the middle button) on the device's front panel. Press and hold this button to power the device on or off.
4.3 Language and Time Settings
After powering on, you can navigate the menu to set the language (Chinese/English) and adjust the calendar clock (year-month-day, hour-minute-second). Use the left and right navigation keys to switch menu items and adjust values.
5. Operating Instructions
5.1 Basic Measurement
Once powered on, the device will automatically begin real-time radiation measurement. The TFT 2.0 color screen displays the instantaneous dose rate, average dose rate, and accumulated dose. The unit of measurement can be switched via the menu.
5.2 Setting Alarms
The device features adjustable dose rate alarm thresholds and metering alarm thresholds. Navigate to the 'Alarm' menu option. Use the left and right navigation keys to select the threshold type and adjust the desired value. The device will trigger both a sound and a light alarm if the measured radiation exceeds these set thresholds.
5.3 Timed Measurements
To set up a timed measurement, navigate to the 'Schedule' menu. Here you can set a start-delay time (00-99 hours) and a measurement duration (00-999 hours). Once the delay countdown is complete, the device will begin measuring, zeroing the instantaneous value, average, and accumulated time. At the end of the measurement duration, the device automatically stores the interval data in its history.
5.4 Accessing and Deleting Data
Historical measurement data can be accessed through the 'Records' menu. The device stores the last 10 measurements. To delete data, navigate to the 'Delete' screen. You can choose to delete current data (resets average value and accumulated time on the measurement page) or historical data (clears all stored history).
6. Maintenance
6.1 Charging
Regularly charge the device using the provided Type-C cable to ensure optimal performance. The built-in 750mAh battery offers approximately 14 days of continuous measurement without particle sound on a full charge.
6.2 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the screen or casing. Ensure no liquids enter the device, especially the sensitive area on the back.
6.3 Storage
Store the HFS-20PRO in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. When storing for extended periods, ensure the battery is partially charged (e.g., 50%) to prolong its lifespan.
7. Troubleshooting
- Device displays "device damaged": This indicates a sensor failure. Please contact customer support for assistance.
- Alarm constantly triggers: Check your set alarm thresholds in the 'Alarm' menu. Adjust them to appropriate levels for your environment.
- Device does not power on: Ensure the device is fully charged. Connect it to a power source using the Type-C cable and check if the green charging light appears. If not, try a different cable or power source.
- Inaccurate readings: Ensure the device is used in an open area away from potential interference. If issues persist, consider a factory reset (if available in menu) or contact support.
