The display is the only system component that is accessed by the user. All user input
to the display is done using the five 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 shut off after about 5 seconds.
2.
If another button (including BATT or LPG) is pressed before the 5 second time is
up for the first 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
level once per second so the user can watch the level change while the tank is
being filled or drained. The display will automatically shut off 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 off.
To read the LPG tank level:
1.
Press the LPG button and release it, the display will show the level in percent on
the LED display. If no other button is pressed, then the display shut off after
about 5 seconds.
2.
If the LPG button is pressed again, a new reading will be obtained and
displayed, and the 5 second timer will be restarted. If the button is held down,
the existing reading is held for as long as the button is pressed, and the display
will shut off 5 seconds after the button is released.
3.
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.
4.
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 filling of the tank.
The gauge should not be used as a full tank shutoff indicator since the LPG
