Multi-Point Linearization
(
LINEAR
)
Up to 32 linearization points can be selected for PV1
and PV2 under the
LINEAR
function. Multi-point lineari-
zation can be used to linearize the display for non-lin-
ear signals such as those from level transmitters used
to measure volume in odd-shaped tanks or to convert
level to flow using weirs and flumes with complex expo-
nent. These points are established via direct entry
(
SCALE
) or with a live calibration signal source (
CAL
).
If the dual-scale level feature has been selected, the
menus for PV1 & PV2 are enabled.

Up to 32 points can be selected for PV1 and PV2.
Round Horizontal Tank
Linearization (
RH TANK
)
This function automatically calculates the volume in a
round horizontal tank with flat ends. It is only available
for PV2 while the meter is in dual-scale mode.
For instructions on how to enable PV2 see
Changing
System Settings (
SYSTEM
) on page 44.
Set the display for the desired decimal point and engi-
neering units before entering the round horizontal
tank function. Select units (inches or cm) for the tank
dimensions. Enter the diameter and the length in
inches or cm and the results will be calculated auto-
matically in US gallons or liters. The unit of measure
for the volume can be changed using the display
menu.
See
Changing the Engineering Units (
UNITS
) on page
29 and Available Unit Classes and Units on page 28
for a list of available volume units. There is no need to
enter scaling values.
