3. Measure error again to see if error has increased or decreased. If error has decreased, continue to
add desired increments until you arrive at an error close to zero, else add decrements.
4. Click on "Update meter" every time a modification is made to this field.
5. Change the phase now to -60° and check if this error is still acceptable. If not, fine tune the values of
Phase (low) again. Ideally, errors should be symmetric for same phase shift on lag and lead conditions.
After the meter has been calibrated, it is possible to see these calibrated values for reference. Click "Meter
calibration factors" to open this screen (sample values only).
