Custom Linearization Curve; Cylindrical Lying Tank; Spherical Tank; Configuration With The Pc Or Hht - ABB 266HSH Operating Instructions Manual

8.10.2 Custom linearization curve

The custom linearization curve transfer function it is used
typically for volumetric level measurement in tanks with an
irregular shape. It can be registered to a freely identifiable
transfer function with a maximum of 22 base points. The first
point is always the zero point, the last is always the final value.
Neither of these points can be altered.
A maximum of 20 points are entered in between by the
instrument itself considering as 0% the LRV and as 100% the
URV.

8.10.3 Cylindrical lying tank

This function is used to measure the volumetric level into a
cylindrical horizontal tank with flat ends.
The transmitter calculates the volume from the measured filling
level.

8.10.4 Spherical Tank

This function is used to measure the volumetric level into a
spherical tank.
The transmitter calculates the volume from the measured filling
level.

8.11 Configuration with the PC or HHT

The 266 transmitters can be configured by either one of the
following device.
— Hand Held terminals like the ABB DHH805, Emerson
Process 375 and 475 provided the 266 EDD has been
downloaded and enabled in the terminal.
You can use a handheld terminal to read out or configure/
calibrate the transmitter. If a communication resistor is installed
in the connected supply unit, you can clamp the handheld
terminal directly along the 1 ... 5V line.
For additional information, refer to the operating instructions
included with the handheld terminal.
If the transmitter has been configured in the factory according
to customer specifications for the measuring point, all you have
to do is mount the transmitter as prescribed (to correct
potential zero shifts, refer to the section "Correcting the zero
shift"), and switch it on. The measuring point will now be ready
for use.
If, however, you wish to make changes to the configuration, a
handheld terminal is required.
