(4) Calculate linear scale constant, CL, using the following equation:
CL= SC/RL
= Linear scale constant
CL
Sc
= Scale of drawing or map
= Alinement constant (found on Calibration Records Sheet provided with
RL
equipment)
(5) Enter three most significant digits of linear scale constant, CL, into
auto-scaler using scaler dials.
(a) Set first most significant digit on left hand dial.
(b) Set second most significant digit on middle dial.
(c) Set third most significant digit on right hand dial.
Example:
If CL is 10.571, left hand dial should read 1, middle dial should read 0,
and right hand dial should read 5.
(6) Set decimal selector according to value of first significant digit of
linear scale constant CL.
NOTE
Decimal selector switch sets decimal place for auto-scaler LED display.
If constant is one or greater, set decimal selector to 0.
If constant is less than one, set decimal selector according to place of
first significant digit.
(7) Place linear measuring probe on line to be measured so that pricking pin
is at starting point.
(8)
Press CLEAR button to clear auto-scaler.
Make measurement by tracing length of line with linear measuring probe.
(9)
(l0)
Press foot switch to activate ACCU and freeze count.
Multiply number shown in auto-scaler LED display to obtain length of line
in feet
