6–6.2.16 Alinement of Linear Measuring Probe - Continued
NOTE
Foot switch must remain depressed until ready
to begin measurement, so that movement and
handling of linear measuring probe will not
increment counter.
d .
Press CLEAR button on auto-scaler.
Depress foot switch to
initiate ACCU and freeze count at 0.
e .
Place linear measuring probe and stand so that pricking pin
is at beginning mark of line.
f .
Release foot switch .
g.
Grasp probe body and roll linear measuring probe along
l e n g t h o f l i n e.
Stop when needle is precisely at end of
l i n e .
h .
Press foot switch.
i .
Divide digital readout on LED display by 10 to determine
alined pulse count reading, RL .
Record this number.
j .
Repeat steps d through i four times.
Average the five pulse
count results obtained from the LED display after each test
measurement to obtain RL v a l u e .
NOTE
If average RL value is not within ±0.2% of
f a c t o r y d e t e r m i n e d RL value, the linear
measuring probe may be defective.
Repeat

and general support maintenance for service
or replacement.

C o m p a r e a v e r a g e R L value to RL value found on Calibration
Records Sheet provided with equipment.

If using preprogrammed cards, Program III, manual
calculation of CL i s n o t n e c e s s a r y .
