Surecom SF 401 Plus Hand-Held Frequency Counter w/ EXTRA SMA-Male 19cm Antenna
msc-030002Description
- 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
- Included an extra 5-003BNC-UV 19cm Antenna SMA-Male 144/430Mhz Antenna
Note: (27MHz to 100MHz It can not be guaranteed and the corresponding normal emission appliance)
To count frequency:
1) Switch the ATT button to left hand side
2) Change the antenna into VHF or Dual Band accordingly

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 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) .
