"Empty" calibration
Step Matrix Entry Significance
1 V0H1 0% Enter »empty«level of zero
2 - »E« Register entry
Note!
•
The »full« calibration is carried out automatically when the product reaches the
switching probe. Since the default display sensitivity is used during this time, the display
at V0H0 may be initially incorrect and analogue signal/relays not function as set.
•
Analogue output and relays are set as described in Chapter 6 and 7.
