Linearization

Entry of a linearization curve
• The linearization curve must be entered in
the same units as the calibration.
• Before entering another linearization curve
delete any other curve present with V2H0: 4.
• A linearization curve can have a maximum
of 11 points.
• The linearization curve must always rise
continuously.
• After entering all pairs of values activate the
linearization curve with V2H0: 1.
• Points on the linearization curvecan be
individually changed by simply entering new
pairs of values. The corrected curve must
also rise continuously.
Caution!
First point of the linearization curve
The level and volume values for the first point
of the linearization must also be registered.
The procedure is as follows:
# VH Entry

4 V2H2 e. g. 0.000 Enter value
5 V2H2 H Register entry by
leaving the field.

Setting the current output
After a linearization, the current output must be
set in the unit of linearization, e. g. volume.
Reset
The values entered in the fields V2H0 ... V2H3
are not affected by a reset.
Errors and warnings in V9H0
When entering a linearization curve the current
output assumes an error and the instrument
stops measuring.
• E605: Display when entering the
linearization curve. The error message
disappears when the linearization curve is
activated.
• E602: The linearization curve rise not
continuously. The number of the last correct
pair of values is automatically shown in
V2H1. Enter the new values in the next line
in V2H2 and V2H3.
• E604: The linearization curve has less than
two pairs of values. Enter more pairs of
values.

4 Types of measurement

Volumetric measurement for linear
relationship between level and volume
The measured value in V0H0 can be shown in
any units of volume.
• The maximum volume at the "full"
calibration point is entered.
Note! The max. volume in V2H5 is
automatically assigned to the "full" calibration
point.
