Setting the Standard Adjuster
Mechanical Instructions Only
These instructions apply to meters equipped with mechanical output accessories only. If your
meter is equipped with an electrical output (i.e., electronic pulser), refer to the manual for
the electrical component your Owner Information Packet.
Refer to the figure at the bottom of this section and follow this procedure to set the standard
adjuster:
1. Remove the dust cover. See the Removing the Dust Cover procedure in Servicing the
Drive Components .
2. Check meter registration by delivering product to a reliable, accurate prover. Perform
multiple delivery tests to verify the meter repeatability.
3. Record the setting that is indicated on the adjuster.
4. Note the difference between the volume of the prover and the volume indicated on the
meter counter.
Calculate the necessary % correction using this formula:
5. Loosen the adjuster clamp screw.
6. When the prover volume is less than the meter counter volume, add the percentage to the
original adjuster setting by turning the thimble towards the arrow marked LARGER
(larger volume). Correct the original setting by approaching the number desired from the
next larger number. For example, if the desired adjuster setting is 2.4, turn the adjuster
thimble to the left to number 5, then to the right to obtain the 2.4 setting. Adjuster is
currently set at 2.3 in the figure below.
7. When the prover volume is more than the meter counter volume, subtract the percentage
from the original adjuster setting by turning the thimble in the direction of the arrow
marked smaller volume percent.
