Step Matrix Entry Significance
1 V9H5 e.g. 672 Reset transmitter
2 - »E« Register entry
Note! See also Section 4.1 Commissioning, V3H5; V3H6
3 V8H0 5 Enter operating mode
4 - »E« Register entry
5 V8H2 4 s Set switching delay to min. 4 s
6 - »E« Register entry
7 V8H3 e.g. 80% Enter installation height of limit switch in same unit
as level in channel 1
8 - »E« Register entry
9 V8H4 0 Enter sensor type: 0 = Liquiphant; 1 =capacitance probe
10 - »E« Register entry
11 V8H5 0 only for capacitance probes (channel 2)
Perform calibration with exposed probe
12 - »E« Register entry
13 V8H6 e.g. 1 only for capacitance probes (channel 2)
Set switching point in Hz,

14 - »E« Register entry
16 V8H7 1 Set correction factor to 1.0
17 - »E« Register entry
"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.
