How To Electronically Calibrate The Sb-100 Meter (E-Cal) - Bennett 3700 Series Installation Manual

How to Electronically Calibrate the SB-100 Meter
The basic calibration procedure assumes that the test can sight glass is graduated in units of cubic
inches or cubic centimeters (milliliters). If the sight glass is in test can percentage units, refer to the
optional calibration procedure in the next section.
1. Under normal dispenser operation, fill a test can to verify proper meter calibration. If the meter is
properly calibrated, the procedure is finished.
2. If the meter is out of calibration, write down the amount of the error from the test can sight glass. The
error amount should be either cubic inches or cubic centimeters (milliliters).
3. Plug in the Manager Keypad to the J6 connector on the CPU/Control Board. Break the seal on the
electronic calibration switch and move the switch to the calibrate position. This brings up the test
can size display. This switch is located on the top of the CPU board.
4. With the Manager Keypad enter the size of the test can and press the ENTER button. The test can
size ranges from 0.1 to 999.9 volume units. When the test can size is entered, the error amount
display appears.
5. Enter the amount of the error recorded previously and press the ENTER button. At this point,
another test may be filled for calibration verification by turning on the pump handle. If another test
can is not desired, proceed to step 7.
6. If another test can is filled, the error amount display appears as soon as the pump handle is turned
off. If the meter is out of calibration, write down the amount of the error from the test can sight glass.
Go to step 5.
7. Move the calibration switch back to the operate position and seal it. Disconnect the Manager
Keypad.
The optional calibration procedure assumes that the test can sight glass is graduated in test can
percentage units rather than cubic inches or cubic centimeters (milliliters) as in the basic calibration
procedure. If the sight glass is in cubic inches or cubic centimeters, refer to the basic calibration
procedure in the previous section.
1. Under normal dispenser operation, fill a test can to verify proper meter calibration. If the meter is
properly calibrated, the procedure is finished.
2. If the meter is out of calibration, write down the amount of the error from the test can sight glass.
The error amount should be a percentage of the test can's volume.
3. Plug in the Manager Keypad to the J6 connector on the CPU/Control Board. Break the seal on the
electronic calibration switch and move the switch to the calibrate position. This brings up the test
can size display.
4. With the Manager Keypad enter the size of the test can and press the ENTER button. The test can
size ranges from 0.1 to 999.9 volume units. When the test can size is entered, the error amount
display appears.
5. The default error amount display is for cubic inches or cubic centimeters. To bring up the percent
error display, press the UP-ARROW button.
6. Enter the amount of the error recorded previously and press the ENTER button. At this point,
another test may be filled for calibration verification by turning on the pump handle. If another test
can is not desired, proceed to step 8.
7. If another test can is filled, the error amount display appears as soon as the pump handle is turned
off. If the meter is out of calibration, write down the amount of the error from the test can sight glass.
Go to step 6.
8. Move the calibration switch back to the operate position and seal it. Disconnect the Manager
Keypad.
