- 9V Battery (Note: Due to shipping regulations, the battery may not be included in some shipments. Please check your package contents.)
- Carrying case
2. Battery Installation
- Locate the battery compartment on the back of the device.
- Open the battery cover.
- Insert a 9V NEDA 1604, IEC 6F22, or JIS 006P battery, observing the correct polarity.
- Close the battery cover securely.
Operating Instructions
The TM-195 features a Liquid-Crystal Display (LCD) with 4-1/2 digits, capable of displaying up to 19999. It uses a digital, triaxial measurement method with isotropic, triaxial directional characteristics.
1. Power On/Off
- Press the power button (usually marked with a circle and a line) to turn the device on.
- To turn off, press and hold the power button. The device also features an auto power-off function, defaulting to 15 minutes, with an adjustable threshold from 0 to 99 minutes.
2. Measurement and Display
- Measurement Range: The device offers one continuous measurement range.
- Display Resolution: 0.1mV/m, 0.1µA/m, 0.001µW/m², 0.001µW/cm².
- Setting Time: Typically 1.5 seconds (0 to 90% measurement value).
- Sample Rate: 1.5 times per second.
- Units: The device supports units such as mV/m, V/m, µA/m, mA/m, µW/m², mW/m², µW/cm². Use the 'UNIT/ENTER' button to cycle through units.
- Display Values: Shows instantaneous measured value, maximum value, average value, or maximum average value. Use the 'MAX/AVG' button to switch between these display modes.
3. Alarm Function
- The device includes an audible alarm (buzzer).
- The alarm function has an adjustable threshold and can be turned ON/OFF. Refer to the full user manual for detailed instructions on setting the alarm threshold.
4. Data Memory
- The TM-195 supports manual data memory and can store up to 200 data sets (Max & AVG records).
- Use the 'REC/TIME' button to record data and the 'HOLD/ALARM' button to hold the current reading. The 'XYZ/MEM' button is used for memory functions.
Applications
The TM-195 is suitable for a wide range of applications, including:
- RF power measurement for transmitters.
- High frequency (RF) electromagnetic wave field strength measurement.
- Mobile phone base station antenna radiation power density measurement.
- Wireless bug finding.
- Wireless communication (CW, TDMA, GSM, DECT) applications.
- Wireless LAN (Wi-Fi) detection and installation.
- Cellular/Cordless phone radiation safety level assessment.
- Microwave oven leakage detection.
- Personal living environment EMF safety assessment.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in its carrying case in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
- Battery Replacement: Replace the 9V battery when the low battery indicator appears on the display.
Troubleshooting
If you encounter issues with your TM-195, consider the following basic troubleshooting steps:
- Device does not power on: Check if the 9V battery is correctly installed and has sufficient charge. Replace the battery if necessary.
- Inaccurate readings: Ensure the device is held correctly and not obstructed. Verify the calibration factor settings.
- No display: Check battery and power connection. If the issue persists, consult the full user manual for more advanced troubleshooting or contact support.
