4.1.3 Standard Operating Screen
– DUAL FLOAT
If you have purchased a JMT with the dual float option enabled,
it will be done so by default, and cannot be changed without
factory assistance. The unit must have two (2) floats to function
properly and will flash “LOST SIGNAL” if second float is not
installed.
The
Standard Operation Screen
in dual float mode will display
both the media level and the interface level, with the % of full
scale and output current of the selected output in

4.1.5 Waveform View
Pressing
Back
from the
Standard Operating Screen
will
display a graph of the signal measured by the instrument. If a
float is detected it will center on the position of that float,
showing the lowest and highest value on the graph, in units
selected in user installation. This will always be in terms of
distance from the tee/enclosure and not the reported level.
Pressing
Up
and
Down
will move the graph further and closer
to 0.0, respectively. The graph will always be scaled from 0-
2.5V, with a horizontal dotted line indicating the trigger level
(ADC Max Voltage). The detected signal must be above trigger
level for the electronics to treat a reading as a valid level signal.
A detected float will be marked with a pair of solid vertical lines, indicating the time at which the signal went
above, and then fell back below the trigger level. If a signal is detected that passes the trigger level, but is
filtered out, a pair of dotted lines will be shown on that part of the signal. The number of signals detected will
be shown in the upper right corner marked with a
“Sig”. If no float is detected, the solid vertical lines of where
the float was detected previously will be displayed.
