Field Strength Meter High Sensitivity Detector Radio Signal 126db Dynamic Antenna Gain Detection DW-400

Field Strength Meter High Sensitivity Detector Radio Signal 126db Dynamic Antenna Gain Detection DW-400

Description:
- Upgrade Version: the field strength value in the middle can be displayed for a second, with the value in the lower right corner for real-time display.
- Digital field strength meter + FM mode adjustable + Speaker, suitable for radio direction finder, falconry, pet tracking, signal interference test, radio field intensity cover intensity test
- Detect given frequency radio signal strength
- The digital field strength meter can display radiation field intensity for high-frequency signal and demodulation monitoring FM mode. When the signal is weak, you can monitor the speaker.

Specifications:
DW-400 Field strength meter (Built-in speaker, can adjust FM mode)
1. Working Frequency: 135-173MHz/200-280MHz/400-520MHz
2. Receive Sensitivity: -126dbm~+0dbm (Stepper 1dbm continuous) (dynamic range: 126db)
3. Working Voltage: 3.6V (Built-in Li-on battery, it can be charged with smart phone charger). It can work 10 hours without standby.
If the speaker is switched on, the working time will decrease.
4. Current Consumption: >=150mA (When the speaker is on, the current consumption will increase.)
5. LCD Screen: colorful backlight
6. 400-470MHz Antenna
7. Size: 80*68*22mm (The antenna and overhang are not included.)
8. Attention: You cannot input signal that is more than 0dbm (1mw radio frequency power), or it will damage the machine. (If it damaged by input strong signal, beyond guarantee range)
9. If it is messy code or signal strength is not around -120dbm after switching on. If the antenna is not connected, please restart the machine. If the antenna is connected, the exotic strong signal causes high display value.

Package Included:
- 1 x Field Strength Meter

Operation Steps:
- Long press the upper right corner button until screen displays "switch on", and then let go, wait for the boot.3 seconds start-up, the upper left corner of the screen shows the frequency, the upper right corner shows the frequency variable range, the middle of the screen shows the frequency of the field strength value, the lower left corner of the screen shows the volume, the lower right corner of the screen is start-up speaker and signal strength option.
Turn the button on the upper right corner, the red bar on the screen back and forth in the upper left corner of the upper right corner frequency adjustable range.
The lower left corner speaker volume set, the lower right corner start-up speaker signal strength option. Back and forth in the upper. When the red bar is below the frequency, press the button on the upper right corner, the frequency displays bright. Then turn the upper right corner knob, you can adjust the frequency.
When the red bar is below the MHz, turn the upper right corner knob, you can adjust the frequency. When the red bar is below the Hz, turn the upper right corner knob, you can adjust the frequency.
- In the same method, you can set and adjust the speaker volume as well as speaker signal strength. Press the upper right corner button to save the parameter.
When you switch on the machine after shutdown, it still displays the last frequency.
Turn the button in the upper right corner of the lower part of the frequency range, and then click on the button in the upper right corner. At this time, the band was revealed, and then turn the button in the upper right corner to select the frequency range of the three frequency bands.
Just press the button in the upper right corner, the band can be saved.
