When the power meter is zeroed, the zero measurement deviation and noise influence
can be reduced, and the accuracy of the RF power measurement can be improved.
 Disable: The zero buttons will be hidden.
 Internal Zeroing: In this way, the power sensor remains connected to the RF signal
during the zeroing process. Zero buttons is displayed.

result. Zero buttons is displayed.
Press the ―Click to perform zeroing‖ button, and the instrument performs the zero
calibration operation of the power meter according to the ―zero calibration type‖ you
selected. This feature can be used to reduce the effects of noise and zero offset on the
measurement results. And the button name will change from ―Click to perform zeroing‖ to
―Zero In Progress...‖ After the zero adjustment is completed, the button name will be
restored to the word ―Click to perform zeroing‖.
Note: If the power meter does not have an internal or external zeroing option, the ―internal‖
and ―external‖ in the drop-down boxes are replaced by the ―Enable‖ option.
