Recording a DAC curve

A T T E N T I O N
Before starting to record a reference curve,
the instrument has to be correctly calibrated
(see Chapter 5.8 Calibrating the USM 36,
page 5-28).
As soon as a new curve is recorded, a possibly already
existing curve must be deleted. If necessary, make sure
that the old curve has been saved to a free dataset be-
fore starting to record a new curve.
