3. crease adjustment is required If meter registration is greater than the test prover measured volume a decrease adjustment is required Remove the seal and seal wire Remove the front cover plate Loosen the screw on the clamping ring The adjuster barrel will now be free to rotate Each small hash mark corresponds to 0 02 adjustment Each of the larger numbers on the rotating barrel corresponds to 0 1 The large numbers engraved into the adjuster body correspond to 1 The entire range of adjustment is 5 with the meter being set at the factory very close to the middle of this range To increase the registered volume rotate the adjuster barrel to the left by the percentage increase desired It is recommended that the barrel be rotated 0 02 more than the desired amount and then backed down to the desired figure This accounts for any slack present in the adjuster mechanism In the example above the barrel would be rotated 16 tick marks on the barrel 15 tick marks x 0 02 0 3 3 10 s plus the one tick mark for slack With the slack removed the barrel would then be rotated one tick mark back to the right to achieve the final adjustment To decrease the registered volume the adjuster barrel is rotated to the right Tighten the screw and clamping ring Run another test and adjust if necessary When calibration is achieved ensure that the screw and clamping ring are tight and then replace the cover plate One complete turn of the
