6.1 Linearization (continuation)
Programming example
When programming the level and flow percent values,
observe the following:
- The starting point of the characteristics (index marker
00) is generated by the instrument itself and
coordinated with the values H = 0.0, L = 0.0.
- The end (last index marker) can be made individually
within the 32 value pairs.
- The last index marker must only consist of 100.0 level
percent and
100.0
flow percent.
Programming acc. to linearity protocol
(see e.g. page 21)
Index marker 01 (level percent)
• Enquire index marker
4.H.01 in the MODEFIELD
• Program 30 % in the PARAMETER FIELD acc. to the
linearization curve
• Then store with STO
Index marker 01 (flow percent)
• Enquire index marker
4.L.01
in the MODEFIELD
• Program 10 % in the PARAMETER FIELD acc. to the
linearization curve
• Then store with STO
etc. acc. to linearity protocol. After programming of all data
- reset to mode range 0
- change display indication to flow proportional indication,
i.e. mode 0 - 13 … 0 - 16
- here in the example activate the programmed
linearization curve, i.e. mode 0 - 18 = 4 .
