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 the signal is weak, which will affect the test results, the signal bar is low. (see Pic.1)
