.Input of unit mass
[See table-1, table-2, and table-3.]
● Timing flat belt
Input the mass per width (mm) x length (m) in "g/mm W x m L"
for unit mass.
Data of capacity can be 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/mm W x m L.
●
Timing V-belt
(Input of belt unit mass from preinstalled data)
When "MASS" button is held down (longer than one second),
belt type is displayed on LCD. Scroll the display with UP button
("2") or DOWN button ("8") until the letter of desired belt type is
highlighted. Then press "MEASURE" button for determining.
● V, V-ribbed belt and wire
Input the mass per meter of length in "g/m length" for unit mass.
Data of capacity can be 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-507, U-505, and 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. (Display of
measured frequency is not changed.)

.Input of belt width or
the number of belts (ribs)
● Timing flat belt
Data of belt width can be input by four significant digits, i.e.
three digits of integer and one digit below decimal point in
millimeters from 000.1 to 999.9 mm.
●
V, V-ribbed belt and wire
Input one (piece) of V-belt and wire.
Input the number of ribs of V-ribbed belt.

. Input of span length
Span length is a distance between contacts with pulley, and can
be calculated by the following equation accurately. Alternatively,
measure the distance between pulley contacts with a measuring
tape for facilitation.
where,
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）
