(8) Place linear measuring probe and stand so that pricking pin is at
beginning mark of line.
(9) Release foot switch.
(10) Grasp probe body and roll linear measuring probe along length of line.
Stop when needle is precisely at end of line.
(11) Press foot switch.
(12) Divide digital readout on LED display by 10 to determine alined pulse
c o u n t r e a d i n g , RL .
(13) Record this number.
(14) Repeat steps (6) through (13) four times.
(15) Average the five pulse count results obtained from the LED display after
e a c h test measurement to obtain R L v a l u e .
