Press the Zero/Cal main menu key and press the
Cal Factor submenu key. Enter the Center Frequency, or press the
Signal Standard key and the
Up/Down arrow keys to select a particular standard. The calibration factors are derived for the corresponding center frequency. The channel number is not required because the calibration factor frequencies are rounded to the nearest 500 MHz. The Cal Factor message in the display window shows
Cal Factor ON if the
Cal Factor command has been properly sent to the sensor.
