If the display doesn’t show 55 gallons, you will have to place the unit into the 55-gallon drum mode.
Refer to “Measurement Mode Selection” procedure below.
Measurement Mode Selection
a) Enter the Select Mode: Press and hold the Refresh/Select button down for 7 seconds.
The display will show “Liter/Gallon” and flash (units mode).
b) Release the Refresh/Select button and then press and hold for 7 seconds to select liters or
gallons. The chosen setting will be displayed and the barrel volume will begin to flash
(volume mode).
c) Press and release the button to scroll through the other settings until desired mode is flashing.
For gallons setting – 55, 30, or 15 gallons can be selected. For Liter setting – 208, 114, or 57
liters can be selected.
d) Press and hold the Refresh/Select button for 5 seconds to select the desired volume setting.
e) After desired volume mode stops flashing, release the button. The unit will then go back into
level monitoring mode.
f) The level reading can be refreshed by momentarily pressing the Refresh / Select button.
The back light will light up and will be on for 15 seconds. When the back light shuts off, the
level reading will be displayed.
6. If the previous four conditions are met, perform the following bench test. Note that current output(mA)
is specific to the DFT-200 series barrel gauge.
Simulate a Full (55 gallons / 20 mA) Reading
a) Place the Digital Fluid-Trac
®
flat on a table top.
b) Press the Refresh/Select button.
c) The display should read 55 gallons (± 4 gallons) or 20 mA (± 1.2 mA), depending on which
output and adaptor(s) being used.
Simulate a Full (35 gallons / 14.2 mA) Reading
a) Place the Digital Fluid-Trac
®
12 inches above the table top. Make sure the bottom of the sensor
is perpendicular to the table top.
b) Press the Refresh/Select button.
c) The display should read approximately 35 gallons or 14.2 mA depending on output type.
