m. Use the Up and/or Down buttons to adjust the
displayed volume to the actual amount
determined in step 7. Then release the
buttons.
i. In this example, press the down button
until 162.5 bbl is displayed.
n. Turn the gauge power off.
o. Turn the gauge power on, without holding any
buttons.
p. Verify that the display matches the actual
volume.
q. Offset calibration is now complete. This
procedure should be done seasonally to
maintain the TD80 rated accuracy.
r. Continue to complete loading.
3. Offset Calibration Using a Measured Level
See Figure 2-1 sample depth chart for the following
calibration step examples.
a. Fill the tank approximately 1/2 to 2/3 full.
Determine the volume by dipping and referring
to a depth chart. An alternative is to place a
wire short at a level 1/2 to 2/3 of the probe
depth in an empty tank.
i. For example
1. Flat bottom tank or center of
sloped bottom, 55” from the
bottom
2. Sloped bottom tank, 26” from
the top (81” - 26” = 55”)
3. Volume is 155.00 bbl
b. Turn the gauge power off.
c. Press and hold either the Up or Down button
while turning on gauge power.
d. Continue to hold the button down until “CAL” is
displayed and then release it.
e. After the normal display start-up sequence,
“CAL” will be displayed flashing for several
seconds and then the current volume
measured by the TD80. This should be close
to the actual volume.
f. Use the Up and/or Down buttons to adjust the
displayed volume to the actual amount. Then
release the buttons.
i. For this example, the display shows
155.0 when offset calibrated
g. Turn the gauge power off.
h. Turn the gauge power on, without holding any
buttons.
i. Verify that the display matches the actual
volume.
j. Offset calibration is now complete. This
procedure should be done seasonally to
maintain the TD80 rated accuracy.
