６-１. How to input the unit
mass（Refer to the unit
mass tables on next page）
● Tooth & Flat timing belt
To input the unit mass is width(mm) ×
length(m) in g/mm width × mLength.
1. Data capacity is 000.1〜999.9g/mm
width × m Length
2. Able to input with four significant
digit figures of three columns of
integers and decimal one column
● Tooth & V belt from the pre-install
data
Push "MASS" bottom more than one
second, belt type shows up on the
screen. With using "UP" or "DOWN"
button to select and push "MEASURE"
to set.
● V, V-Ribbed belt and Wire
Input the mass per meter of length in
"g/m length" for unit mass.
Able to input by four significant digits,
i.e. three digits of integer and one digit
below decimal point from 000.1 up to
999.9 g/m L. Unit mass corresponds
to one piece for V-belt and wire, and
one rib for V-ribbed belt.
Note: Unit mass of U-550,U-508, U-507,
and U-505, U-305 is 10 times the input of
conventional type U-303 since the input
unit has been changed.
Therefore, when a value is input in
conventional unit mass （g/cm2）,
measured tension is displayed in 1/10.
（No change for the measured frequency
on the screen）
６-２. How to input the belt
width or the number of
belts (ribs)
● Timing or Flat belt
To put the date is for belt width is
000.1mm〜999.9mm, three digits of
integer and one digit below decimal
point in mm.
● V, V ribbed belt, Wire
For V belt and Wire, put one piece.
For V ribbed belt, put the number of
ribs of V-ribbed belt.
６-３. How to put the value of
span length
Span length is a distance between
contacts with pulley, and can be
calculated by the f following calculating
formula.
Alternatively, measure the distance
between pulley contacts with a tape
measure and put.
S ：Span length （mm）
C ：Distance between axes （mm）
Dp：Large pulley pitch outer diameter（mm）
dp：Small pulley pitch outer diameter（mm）
S＝ C − （Dp−dp）
