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 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-
II. At least one calibration must be set up to allow deliveries.
PULSES/UNIT
This field is the number of pulse edges that the LCR-II 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-II, "zeroing" out the error. Refill the prover. Check to
ensure that the prover and LCR-II gross volumes are within tolerance limits. If not, enter the new
prover volume, and retest.
Press and the cursor will move to:
GROSS QTY
This field displays the gross delivery total for the product being delivered. DISPLAY ONLY.
