Electronic Calibration

         Section 3.0.1 Calibrating Using Electronic

                       Factors

Check the Calibration of the Dispenser in question. If the Dispenser is not within tolerance and the Dispenser doesn’t have a mechanical calibrator or cannot be manually calibrated at the meter, the following procedure must be followed:

  • Open the dial face to cut and remove the Measurement Canada seal on the SW4 switch of the CPU Board.
  • Be certain the Inspection Switch is switched to the edge of the CPU BD. (off position)
  • Turn the Manager Switch on, the displays will show dashes
  • Toggle the Inspector Switch ON then back OFF. The Display will read "INSP 0".
  • Using the "ID" key, change "0" to "6". Press the "EN" Key and the display will show "Calib 0".
  • Using the "ID" key, change "0" to "1" (indicating factor #1). Press "EN" and the display will show "calib

000" (This step will be repeated for all 4 or 6 factors)

  • If there is a different number then 000, It would be best to use the keypad and zero the existing numbers.
  • Dispense the product in a prover can to the desired quantity and compare to the Displayed Gross Read (top main display when manager key is turned).
  • On the Meter Correction Factor Chart locate the amount of product the meter is out by under the READING column, beside the percentage of error, is the appropriate factor needed for correction.
  • As a rule, factors 3 and 4 on a Retail Dispenser; factors 5 and 6 on a High Speed Dispenser should be adjusted to the same correction number if fast flow is out of tolerance
  • If slow flow is not within tolerance, locate the amount the slow flow is out by on the Meter Correction Factor Chart and insert the factor in only factors 1 and 2 on Retail Dispensers and factors 1 to 4 on High Speed Dispensers.

Note: Factors cannot be set more than 12 factors apart from each level of speed (factors 1 to 4 or 6).

 

Formula For Calculating Percentage on Provers

Greater Than 20 Liters

 


 

Example #1:

Calibrated prover reading is 20.000.

Gross Register Reading from the pump Top Display when Manager Key is in the ON position READS 20.132.

 


Meter correction is NEGATIVE 0.66 % refer to "Prover Reading (low)" column. Locate 0.66% in the correction column and read the factor column, Value is 223.

This factor value would be inputted in factors 1-4, or 1-6. See Option

Example #2:

Calibrated prover reading is 20.000.

Gross Register Reading from the pump Top Display when Manager Key is in the ON position READS 19.868.

 


Meter correction is POSITIVE 0.66 % refer to "Prover Reading (high)" column. Locate + 0.66% in the correction column and read the factor column, Value is 33.

This factor value would be inputted in factors 1-4, or 1-6. See Option
