4.5.4
Pulse Output K-Factor (
PulsE
)
The pulse output K-factor corresponds to the total units (e.g. gallons) needed to generate one pulse.
For example, if the K-factor value is set to 10, one pulse is generated for every 10 counts
incremented on the display.
If the pulse output exceeds the programmed output frequency, pulses are accumulated as pending.
Pulses will continue to output until the buffer is emptied or the total is reset from the front panel.
4.5.5
Advanced Function Selection (
FUNCTN
)
The Advanced Function menu is used to select the advanced function to be applied to the input:
linear, square root, programmable exponent, or round horizontal tank volume calculation. The
multi-point linearization is part of the linear function selection.
Meters are set up at the factory for linear function with 2-point linearization. The linear function
provides a display that is linear with respect to the input signal.
4.5.6
Multi-Point Linearization (
lnEAr
)
Up to 32 linearization points can be selected under the Linear function. 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 or to convert level to flow using weirs and flumes that
require a complex exponent. These points are established via direct entry (SCALE) or with an
external calibration signal (CAL).
4.5.7
Manual Entry (
SCALE
)
Manual entry of the linearization data is done once the number of points has been selected
(
NO PTS
). Input signal levels (InP 1-32) for up to 32 points, along with the desired/corresponding
meter reading (dSP 1-32) should be entered for each linearization point. See Figure 9 on page 31.
4.5.8
External Calibration (
CAL
)
Linearization data can be entered using a known accurate signal source (InP 1-32) and then
entering the desired/corresponding meter reading (disp 1-32) for that in-put signal level. See
Figure 9 on page 31.
