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) .
