5.4.1.
Meter Adjustment
While the dispensers leave the factory properly adjusted, rough handling in
transit or special installation conditions can change this. Therefore, before
placing the dispenser in operation, these items must be checked and adjusted, if
required.
If meter adjustment is required, the adjustment knob is located on the top of the
meter; see Figure 5-7. If the test can reads low, break the seal, lift the adjustment
knob and turn in a clockwise direction, viewing the knob from the top of the
meter. The lower portion of the knob is hexagonal and, in a normal position, the
portion of the knob is inserted in the output shaft assembly. There are 18 vertical
notches within the shaft, therefore, as the adjustment is made, the knob can be
felt to click over the leading edge of the notches. Each notch is equivalent to a
correction of approximately one cubic inch in five gallons. After the meter has
been adjusted and brought within tolerance, replace the seal wire and seal by
pinching the lead lock on the wire.
FIGURE 5-6. METER CUTAWAY.
The meter is, in effect, a three-cylinder motor, using cylinders ‘B’ and ‘C’
and chamber ‘D’ as the three cylinders
