Instruction Manual
Determination
of the scaling
parameters
• Determine the resolution of the position sensor ‘dX’ (displacement per
counting edge) and calculate it to the unit to be displayed
• Define the resolution of the meter ‘dA’ (same unit as dx)
• Multiplier’ = dX, Divisor’ = dA
• Insert and transform multiplier and divisor by extension or reduction
• Set decimal point
• With the decimal divisor an additional shift right can be made.
As an alternative to the resolution parameters dX and dA the scaling para-
meters can be calculated by the measurement range parameters DX (dis-
play value for end of range) and DA (counting pulses for end of range).
Calculating examples for the scaling
1a. Meter for cable actuated position sensor model WS10 – 1000 – 25
– PP530
Least significant Digit (LSD) of the display has to be equivalent to 0.1 mm
The resolution with times 4 counting mode is 25 • 4 = 100 pulse edges
Resolution of the position sensor: 100 pulse edges per mm:
dX
= 0.01
mm
Resolution of the meter:
dA
= 0.1
mm
Multiplier’ = dX
= 0.01
Divisor’ = dA
= 0.1
Insert the values and extend / reduce:
Multiplier
= 1
Divisor
= 10
Set decimal point between the first and the second digit from the right hand
side
1b. Alternative calculation of example 1a
The display value for end of range has to be 10000
Display value for end of range DX=10000
Counting pulses for end of range
DA=1000 mm • (25 • 4) pulses/mm
Insert the values and extend / reduce:
Multiplier
= 1
Divisor
= 10
