Description
The yo-yo
ballrope extension test instrument makes the length
measuring system( to calculate the elongation length) and the yo-yo
ball installed in the same spindle for rotating.
The test process is controlled
by intelligent MCU, read the turns of the trolling reel through the
encoder pulse, calculate the increment of each circle by
considering the line of the reel increasing on the first circle.
And improve the measurement accuracy value by taking multi-point to
calculate.
a) Interface display: rotating speed,
length, start/stop/reset. (digital display, page display the speed
and length);
b) Length measuring system, DC motor
with speed adjustment, intelligent MCU control.
c) Wall fixing suport or floor
stand seat(adjustable)
d) Encoder and intelligent
control signal transmission system
e) Rotating
speed:****0(adjustable)
f) Stroke：*****0MM(adjustable)
g) Standard:
ASTM*****8
