Lap Pad Calibration & Set-up

STEP 6: PRODUCT CALIBRATION CONTINUED

COMPENSATION TYPE^ CONTINUED

Scroll through the choices: Linear F, Linear C, API Table 24, API Table 54, API Table 6B, API Table
54B

, API Table 54C, API Table 54D, NH3 or NONE. If "NONE" is selected, deliveries will be in gross

quantities only. Net Quantities will read " 0" on the screen. Refer to the Compensation Types and

Parameters table (Appendix A) when choosing the type of compensation to be used.

COMP PARAM

This field contains the coefficient of expansion, the standard density, API gravity, or the specific gravity

that will be used with the COMPENSATION TYPE selected in the previous field. Enter a number based

on the COMPENSATION TYPE and the product that is being metered. Refer to the Compensation

Types and Parameters table found in Appendix A.

BASE TEMP

This field is used to set the base temperature for temperature compensated deliveries when using

either the Linear C or Linear F Compensation type. It defaults to either 60°F or 15°C when using

either the API tables or NH3. Enter a number. Press ENTER to return to the top line.

Press LLLLL and the cursor will move to

#^ (Product Number)

This number will correspond to one of the four product types/calibrations that can be set up in the LCR.

At least one calibration must be set up to allow deliveries.

PULSES/UNIT

This field is the number of pulse edges that the LCR counts per unit of measure. (Only Gross Volume

applies). This number is used to scale the PROVER QTY (Gross).

PROVER QTY

This field displays the metered volume. When this value is overwritten with the actual PROVER QTY,

a new PULSES/UNIT (k-Factor) will be recalculated automatically. (Only for Calibration use.) If this is

the initial calibration for this meter , first enter the rest of the PRODUCT CALIBRATION data before

entering this field. Once the other PRODUCT CALIBRATION parameters are entered, press START

and fill up a reliable prover. As the prover is filled, this field will increment, displaying a volume based

on the existing PULSES/UNIT parameter. After the prover has been filled, press PRINT and enter the

exact prover reading in place of the reading displayed. When the new reading is entered, the

PULSES/

UNIT

parameter will be recalculated by the LCR, "zeroing" out the error . Refill the prover. Check to

ensure that the prover and LCR gross volumes are within tolerance limits. If not, enter the new prover

volume, and retest.

Press LLLLL and the cursor will move to:

GROSS QTY

This field displays the gross delivery total for the product being delivered. DISPLAY ONLY.
