High Sensitivity DC9V Field Strength Indicator Meter 85C1 20MHz-6.5G Radio Detector 
 

Specification:

- Operating frequency: 20MHz-6.5G
- Power supply: DC-9V
- Working current: < 3mA
- The built-in battery can work continuously for over 240h, when the amplitude adjustment knob clockwise rotation to the end, the pointer cannot reach to full, then should replace the battery.
- The test is completed, it is best to close the amplitude adjustment knob is used to disconnect the internal power supply to avoid power is still power.
- Sensitivity: adjustable, general test GPS or GSM mobile phone signal is about 1-2 meters, test CDMA mobile phone signal is about 10-30cm (It despend on the distance between mobile phone or GPS positioning and the base station.The base station distance is farther, the detection distance is farther.)
- Equipped with pull rod antenna, according to the different frequency, the length of the rod is adjusted appropriately, the best test result has been achieved.
- Test is completed, it is best to turn off the amplitude adjustment knob to disconnect the built-in power supply and avoid power consumption.
- This product goes through the HP8921A radio integrated test instrument test, the indicators are guaranteed.

Product advantages:
- The appearance is simple and beautiful.
- Wide frequency band, high sensitivity, 20MHz-6.5G can be tested. (The full list can be transferred without emission)
- Pointer amplitude can be adjusted! (To protect the header)
- Built-in automatic damping function, which is buffering function to prevent excessive damage to the hands swing
- Small size, easy to carry! Size: 90 * 115 * 55mm (excluding protrusions antenna portion)

Test Sensitivity:
- 10-50mW:  transmitter distance 10-50cm
- 50mW-200mW:  transmitter distance 50cm-1m.
- 300mW-1W:  transmitter distance 1-5 meters.
- 1W-5W: about 5-20 meters.

Note: Above sensitivity is just a probably data , because the sensitivity is adjustable, when you can not launch full table, which depends on electromagnetic interference environment surrounding the serious situation, and that is to reach the field strength meter antenna signal strength must be greater than around only the interference signal strength can be measured.

How to use:
Before using the front panel of "adjustments" knob is rotated clockwise, turn on the power to hear the sound of Cartagena clockwise to adjust the sensitivity of field strength meter,
U take walkie-talkie are away from the field strength meter for 2-5 meter, do not get too close! In order to avoid too strong signal to burn Signal Strength Meter!
Then press the PTT button of walkie-talkie, so the intercom turn into the launch state, then Level Meter pointer should signal indication, the stronger signal the greater indicater!
 
Amplitude adjustment: when field strength meter pointer exceeds the maximum range, you can adjust "amplitude modulation" so that pointer to the appropriate location,
 
Antenna maximum gain point test method:
- In order to quickly change frequencies, U should use keyboard walkie-talkie.
-Connect walkie-talkie and antenna feeder, place the antenna close to the field strength meter (distance depending on the environment), as far as possible be placed in a vertical radiation angle of the antenna, and plan way of antenna is same.
- Set walkie-talkie frequency, press the launch button, observe and write the meter reading. Then choose other frequencies of intercom, so that the intercom turn into the launch state again, observe the meter reading. Thencompare the readings for each frequency! So you can know the best frequency for antenna!
