Introduction:
 

  • The frequency meter capable of measuring the parameters of the frequency of the continuous carrier signal walkie-talkies , with signal strength indicator. it is the tool of choice for maintenance personnel,test frequency and signal strength of wireless enthusiasts.
  • This portable frequency counter is designed for counting continuous wave signal comes from Two-way Radio. 
  • There are easy ranges for you to choose. The ranges cover most of the frequency of the two way radios you want to measure. 
  • Its four-button control is easy to use and its small size allows you to carry it anywhere you like.
  •  Work by  TCXO(Temperature Compensate X'tal (crystal) Oscillator) ,In the range of -45 ℃ ~ 65 ℃ can reach ± 2 ~ ± 4ppm accuracy
  • This include very interesting frequency areas such as 2m HAM radio, all VHF and UHF
  • DMR Radio signal e frequency counter.
  • Easy Battery level

Power On/Off                                    
Power On –Press and Hold down the [black key] by 2 second 
Power Off –Press and Hold down the [black key] by 4 second of number count down to 0
Charging the battery 
Plug the Power cord into adaptor , Micro usb connected SF-401, The Led indicating:
       *The RED Led is light - Charging          * The Green Led is light - Full 
How to check Frequency measuring.    See PIC.3

The transmitter near the frequency counter anetnna , see the signal reception conditions is zone green, you can test. Please see Pic.3
cautions: 
e.g. display 1800.000Mhz  , The transmitter distance is too close to the frequency counter will affect the test results, , the signal bar is red .(see Pic.1)
e.g. display 0.000, , The transmitter distance is too far to the frequency counter and signal is weak ,will affect the test results,  the signal bar is low .(see Pic.1)
