INTRODUCTION:
The SS-10  Field  Strength  Meter  is  ideal  for  reading  relative  field  strength  from your antenna. 
It is a compact unit that fits in the palm of your hand and can be  taken  anywhere.    
The  best  part  of  using  it  is  that  you  now  can  tell  if  your  antenna  is  radiating  or  not  by  simply  holding  the  unit  near  your  antenna  and  adjusting  the  sensitivity.    Also,  by  taking  measurements,  you  can  find  out  relatively how strong your antenna field is. Operation The  SS-10  Field  Strength  Meter  is  very  simple  to  use.    It  requires  no  power  because  your  antenna  field  provides  the  power  necessary  to  run  the  meter.    
Simply raise the single whip antenna on your unit, stand several feet away, and adjust  the  sensitivity  knob  on  the  front,  it’s  that  easy.    
You  want  to  ensure  that  the  whip  antenna  is  parallel  with  the  polarity  of  the  antenna  you  are  reading.   
Now you can read the relative field strength of your antenna. 
Technical Assistance If you have any problem with this unit first check the appropriate section of this manual.  If  the  manual  does  not  reference  your  problem  or  your  problem  is  not  solved  by  reading  the  manual  you  may  call  SURECOM Technical Service at 852-54457217.  You will be best helped if you have your  unit, manual  and  all  information  on  your  station  handy  so  you  can  answer  any questions the technicians may ask. You  can  also  send  questions  by  mail  to  SURECOM.COM.HK 

Features:
The appearance is simple and efficient, beautiful and generous.
Frequency bandwidth, high sensitivity. 100KHz-3000MHz (with antenna ), please use different frequency antennas to test signals with different frequencies for better effect and sensitivity)
The pointer amplitude can be adjusted (to protect the meter)
Built-in automatic damping function, which is the buffer function, prevents the needle from swinging too fast and causing damage.
Small size, easy to carry, size: 75 x 100 x 64mm (excluding the raised antenna part) 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Instructions for use:
Before use, please rotate the "amplitude adjustment" to the left most end. The length of the antenna to be pulled depends on the frequency of the test. It is better to have 1/4 wave as much as possible. The handheld walkie-talkie is about one meter away from the field strength meter. Don't be too close! In order to avoid the signal is too strong to burn the field strength meter! Then press the walkie-talkie PTT button to make the walkie-talkie enter the launch state. At this time, the pointer of the field strength meter should have a signal indication. The stronger the signal, the greater the indication!

Amplitude adjustment: If the field strength indicator indicates that the maximum range is exceeded, the "amplitude adjustment" can be adjusted to let the pointer indicate the appropriate position.

Method for testing the maximum gain point of an antenna
1. In order to change the frequency conveniently and quickly, you should use the keyboard to set the frequency walkie-talkie manually.
2. Link the walkie-talkie and antenna feeders, place the field strength meter near the antenna (depending on the environment), place it within the vertical radiation angle of the antenna as much as possible, and the antenna planning method is best.
3. Set the frequency of the walkie-talkie, press the launch button, observe the meter reading, and register the meter reading. Then set the walkie-talkie to other frequency points, let the walkie-talkie enter the launch state again, observe the meter reading and then compare the readings of each frequency point! You can know the best frequency/segment of the antenna under test!

A typical field-strength meter is shown in Figure 1.  This is a simple passive (unpowered) circuit in which radio frequency energy is intercepted by the antenna, rectified to DC, and then used to directly drive the meter.  The maximum sensitivity of this circuit is based primarily on several factors:
The gain of the antenna:  How much of the signal is actually intercepted.
The sensitivity of the meter movement being used.
The nature of the diodes being used.
