k-Factor Adjustment (example):
Presume that the LCR-II register displayed "101.235" Units and the prover volume was determined to be "100.593" units at
1.
the
end of step 9. ("Units" represents the units of measure as designated on the front cover of the LCR-II.)
2. When INCREASE is pressed in Step 9 above, the left most digit of the LCR-II register will be flashing on and off, indicating
that
it can be changed. To change this value, press INCREASE to scroll through 0-9. The display digits will wrap around to 0 after
9
has been reached. When the desired value for the first position has been reached, press SELECT and the next digit to the
right
will flash on and off. In this example, no adjustment to the first digit is necessary.
The second digit also does not require adjustment, so press SELECT to advance to the third digit. The third digit, "1", will be
3.
flashing on and off and needs to be changed to 0 in order to match the prover volume. Press INCREASE to scroll through the
digits until "0" is displayed. Press SELECT to accept that value and advance to the next digit, "2".
Press INCREASE until the number "5" is displayed. Press SELECT to advance to the next digit, "3". Continue in this fashion
4.
until all the digits on the display are adjusted to the prover volume: "100.593". When this is complete, none of the digits will
be
flashing on the display. A new k-Factor is recorded by the LCR-II. Turn the Selector Switch clock-wise to exit
calibration/prover
mode.
If a number is entered in this example that results in an unacceptable k-Factor, the display will show "Error". When this
5.
press SELECT and return to Step 7 and conduct another prover run.
