10.4.3 Re-performing a calibration
A calibration can be performed by clicking on the corresponding calibration icon in the Home ribbon.
• Clicking on a calibration icon (e.g. Full-Range Gain calibration ) opens the calibration
dialog
• The calibration measurement can be started by clicking the start button .
• After the calibration is the calibration dialog can be closed
• The calibration icon turns green indicating that the calibration is now active .
From now on, this calibration is used for the measurement.
A calibration can be disabled and enabled by clicking on its calibration icon.
To re-performed a calibration, open the calibration dialog by clicking on the arrow on the
bottom of the calibration icon . Then select .
Calibration can then be re-performed by pressing the Start button.
10.4.4 Full-Range calibration below 10 Hz
Full-Range calibration measures between 10 Hz and 50 MHz at factory pre-defined frequencies. Full-
Range calibration normally starts at 10 Hz to reduce calibration time.
If you decide that frequencies between 1 Hz and 10 Hz must be included in the Full-Range
calibration, you must set the Start Frequency to a value <10 Hz before executing the Full-
Range calibration.
Alternatively User-Range calibration might be more applicable in that case.
Full-Range calibration frequency range:
• If Start Frequency is set ≥10 Hz, then Full-Range calibration will run from 10 Hz to 50 MHz
• If Start Frequency is set <10 Hz, then Full-Range calibration will run from 1 Hz to 50 MHz
If a Full-Range calibration has been performed at a Start Frequency >10 Hz and Start
Frequency is changed to a value <10 Hz after calibration, the correction value at 10 Hz
will be extrapolated to 1 Hz. This is indicated by an orange Full-Range calibration icon.
Re-performing calibration will run the calibration from 1 Hz and the icon will turn green
again.
Note that the calibration takes significantly longer when it starts at 1 Hz.
