T
he display is the only system component that is accessed by
the user. All user input to the display is done using the ve
buttons along the bottom of the display. Operation of the display
is as follows:
To read a water or sewer tank level:
1. Press the button corresponding to the tank to be checked and
release it, the display will show the level in percent on the LED
display. If no other button is pressed, then the display will
shut o after about 5 seconds.
2. If another button (including BATT or LPG) is pressed before
the 5 second time is up for the rst button, the display will
immediately switch to showing the new level or voltage. The
5 second timeout is restarted every time a button is pressed.
3. To continuously display a reading, press and release the
desired button, and then press the same button a second
time. When the button is released, the display will be in hold
mode, which is indicated by the decimal point on the right
hand side turning on. While the display is in the hold mode
it will recheck the held level every 2 - 3 seconds so the user
can watch the level change while the tank is being lled or
drained. The other tanks will continue to be scanned every
10 - 15 seconds. The display will automatically shut o after
5 minutes in hold mode. To end the hold mode before the 5
minutes is up, press any tank button, and the display will shut
o.
To read the LPG tank level:
1. Press the LPG button and release it, the display will show the
LPG level in percent on the LED display. If no other button is
pressed, then the display will shut o after about 5 seconds.
2. If another button is pressed before the 5 second time is up
for the LPG button, the display will immediately switch to
showing the new level or voltage. The 5 second timeout is
restarted every time a button is pressed.
3. There is no hold mode for the LPG. The LPG tank level cannot
change fast enough to justify the use of the hold function,
except during lling of the tank. The gauge should not be
used as a full tank shuto indicator since the LPG sender in
the tank is not reliable or accurate enough to be used as a
safe indicator of a full tank.
