Product Description

SURECOM Frequency meter SF401 Plus New Version 
Portable Frequency Counter with CTCCSS/DCS Decoder

 

New Function Frequency Counter for DIGITAL Radio

  •  

     

     
    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.

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 antenna , 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)
Note: (27MHz to 100MHz It can not be guaranteed and the corresponding normal emission appliance) .
