Figure 8.16 – Calibration of the device
Note
– To cancel (erase) this or that calibration, click on the
Erase
button, and reconnect the appropriate
calibration measure, calibrate the device again.
8.5.4. On the screen in the plot display mode, the calibration information will appear in the lower information
line:
No Cal
– custom calibration no. The device is factory calibrated.
Cal
– Calibrated by user. Calibration and frequency plan match. In this mode, the measurement results are
the most accurate.
Cal. Int
– The frequency plan does not coincide with the reference at which calibration was performed, but
the frequencies lie within the calibration range. The measurement accuracy is lower, since the device uses a
mathematical method for calculating calibrations based on interpolation.
Cal. Ext
– The frequency plan does not coincide with the reference at which the calibration was performed,
but the frequencies are outside the calibration range. Measurement accuracy is the lowest since the device uses a
mathematical method for calculating calibrations based on extrapolation.
Note
– When you exit the
Calibration
menu until the full calibration process is completed, a warning will be
displayed on the screen, as in Figure 8.17. You must either return to the menu by clicking
Back
and complete the
calibration process, or exit the menu by clicking
OK
. In the latter case, when carrying out measurements, the
factory calibration of the device will be applied.
