begins the calibration at the starting frequency specified in the Data Acquisition
Screen. The message:
Taking Data
is displayed at the bottom of the screen. When the first stack is complete, the message:
Processing
appears and the screen displays the un-normalized results. However, these results are quickly
erased. Review the data in Data Mode after the calibration. The internal beeper sounds an alert
at the completion of the calibration of the first frequency. The receiver then:
Increments the frequency by a factor of two
Increments the cycles by a factor of two
Performs a calibration at the new frequency
Displays the results
This process is repeated until the maximum frequency has been calibrated. The program then
returns to the starting frequency and exits the automatic calibration mode.
Zonge recommends immediately performing a system check (see Section 6, page 10) at any
frequency to spot-check the automatic calibration.
