6. NOK: The switch point determined is under 5 % of the measuring range and cannot be
accepted because the switch point must be at least 5 % greater than the switchback

deviations at the switch point, however. Recommendation: Repeat the learning process
(points 1 to 4) until "OK" appears on the display.
