3.8.3 Volume Display Scaling (
VOLSCAL
)
Volume may be scaled as a function of the level display. It may use up to 32-point linearization.
The multi-point linearization can be used to linearize the display for non-linear signals such as
those from level transmitters used to measure volume in odd-shaped tanks.
To display the volume, select a bottom display including the volume display in the Display menu
as shown in Configuring the Lower Display (
DISPLAY ).
To scale the volume display, select the decimal point location (0, 1, 2, 3, or 4), then enter the
level in engineering units for input 1, the corresponding volume display value, and the same for
input 2.
After entering the display 2 value, confirm the new volume scale by pressing
ENTER at the Save
menu.
3.8.4 Level Input Live Signal Calibration (
LVL CAL
)
The meter can be calibrated using a current source instead of scaling. This process will override
previously programmed scaling of the level display.
The use of a calibrated signal source is strongly recommended.
