Electronically Calibrating the SB-100 (Standard Flow) and FPP (High Flow) METER (E-CAL)
Step 6 - You can also enter error as a % instead of as a cubic inch. To do this,
press the "Up arrow" and the display should say "PC Err".
Note - In almost all cases you should enter the test can error as a cubic inch read-
ing and not as a percentage. See Fig. 1.
Step 7 – Once you have entered your error press the "Enter" button for the sys-
tem to accept your change. If your number was too high , you may get a message
that says "Out of Range". If this is happens, try entering a smaller error. If you
continue to get this error, contact Bennett Technical Support. Otherwise, when
you press "Enter", you should see a message "Cal On". See Fig. 2.
Note - The amount of the error that you input to the system is not displayed here.
To view the calibration setting you must go to mode 27.
Step 8 - Return the system to normal operation by turning the ecal switch back to
the "off" position. Run another test can to verify that the system calibration is
working properly and, if so, reseal the calibration switch. If not, repeat steps 1-7
as described above.
Step 9 - Viewing the current calibration setting. Whenever you want to view
the current calibration setting, you must do this in Mode 27. Mode 27 displays
the current electronic calibration value in the system. Get to mode 27 the way
you would get to any programming mode. See Fig. 3 and 4. Note - The number
displayed in mode 27 is a "View Only" parameter (you cannot change in this
mode) and is represented as a %. Even though you may have entered the error as
a cubic inch, it is always displayed as a %.
Notes regarding the calibration procedure:
1 - Always pump "Fast Flow" into the test can until you get close to the end of
the sample.
2 - Never use the Local Preset to preset the amount of fuel for the sample.

Fig. 1 - You can also enter the test
can sample error as a percentage,
but, most people don not do this.
Fig. 2 - After you enter your error
and press the "Enter" button, you will
see a message that says "Cal On".
This indicates that the calibration
parameter that you entered was ac-
cepted and that Electronic Calibration
is on.
Fig. 3 - Code (Mode) 27 is used to
view the current electronic cali-
bration value.
Fig. 4 - Mode 27 displays the current
electronic calibration value.
