5. Setup
5.1 Battery Installation
- Locate the battery compartment cover on the rear of the meter unit.
- Slide or unclip the cover to open it.
- Insert the included 9V battery, ensuring correct polarity (+/-).
- Replace the battery compartment cover and secure it.
5.2 Powering On/Off
- To power on the device, press the green power button located below the display.
- To power off the device, press and hold the green power button until the display turns off.
- The device features an auto power-off function, with a default time of 15 minutes, adjustable from 0 to 99 minutes.
6. Operating Instructions
6.1 Basic Measurement
- Power on the meter. The display will show the instantaneous RF field strength.
- Hold the meter by the handle, keeping the spherical probe away from your body to avoid interference.
- Move the meter slowly in the area you wish to measure. The display will update in real-time.
6.2 Unit Selection
- Press the 'UNIT/ENTER' button to cycle through available measurement units: mV/m, V/m, µA/m, mA/m, µW/m², mW/m², µW/cm².
- Select the desired unit for your measurement.
6.3 Max/Avg Measurement and Data Hold
- MAX/AVG: Press the 'MAX/AVG' button to switch between instantaneous, maximum, average, or maximum average value display modes. This allows you to observe peak readings or average exposure over time.
- HOLD: Press the 'HOLD/ALARM' button briefly to freeze the current reading on the display. Press again to release.
6.4 Alarm Function
- The HF-B8G features an adjustable alarm threshold. When the measured value exceeds this threshold, an audible buzzer will sound.
- To adjust the alarm threshold or turn the alarm ON/OFF, refer to the detailed instructions in the full user manual (PDF document).
6.5 Data Memory
- The meter can manually store up to 200 data sets, including maximum and average readings.
- Use the 'SET' and 'MEM' buttons to access and manage stored data. Consult the full user manual for detailed data logging and recall procedures.
7. Maintenance
7.1 Battery Replacement
When the battery indicator on the display shows low power, replace the 9V battery as described in the 'Battery Installation' section (5.1). A low battery can affect measurement accuracy.
7.2 Cleaning
- Wipe the meter's exterior with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals.
- Ensure no moisture enters the device.
7.3 Storage
- When not in use for extended periods, remove the battery to prevent leakage.
- Store the meter in its protective carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Storage temperature range: -10°C to +60°C.
- Storage humidity range: 0% to 80% RH.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Battery incorrectly installed or depleted | Check battery polarity; replace with a fresh 9V battery. |
| Inconsistent or fluctuating readings | Low battery charge; nearby interference; rapid environmental changes | Ensure battery is fully charged. Move away from other electronic devices. Allow meter to stabilize in new environment. |
| Display is blank or unreadable | Extreme temperature exposure; display malfunction | Move to an environment within operating temperature range. If problem persists, contact support. |
| Buttons are unresponsive | Temporary software glitch; physical damage | Remove and reinsert battery to reset. If problem persists, contact support. |
