Belt type category is shown up by pressing MASS button more than one second.
And choose by UP or DOWN button and push MEASURE button for confirmation.
＊Showing unit : g/m.
＊CAT(rough standard), tension and frequency won't be shown without selecting belt type.

＊To pass on, press SELECT button back to back, to jump in the number, press the wished
number directly on it.
Please press the number continuously to call out larger than the number ten.
●【Call out the measured result】
It is able to confirm the latest 500 data by pressing more than one second.
To select the result, press UP or DOWM button. To jump the data, Press those button more than
one second.
＊The result is recorded in order from Rec.001, it will be overwritten when the records stray the
latest 500 results.
＊The result will be lost if the battery is removed for a long time.

There are four kinds of sensors.
Cord type
Because the size of this senor is a narrow path of φ 12.5mm, it is measurable by
every places.
Flat type
This is the free pipe of the flat shape with thickness 10mm and 20mm in width.
Especially for the right angle direction in a particularly small place.
Long arm type
By using this sensor, it is possible to measure that the main body is hard to
reach.
Electromagnetic type
This react to the electromagnetic vibration, unaffected by the neighboring
noise, the measurement is possible under the vibration decrement early.
However, an application such as the pasting of a thin magnetic film or the magnetic paint is
necessary for a measurement side in the case of a rubber belt.
This cable connects U-550 with PCs, and transfer the measured data.

Unit mass belt width span indication example
●Tension numerical number is shown by three digits from
0.01 〜 99,900.
●Frequency numerical number is shown by three digits
from 10.0 〜 5,000 Hz.
●The red light and ERROR will be shown on the screen
when the result of the measure is out of the standard
range.
NOTE: If the standard range over occurs after the result is
shown, it beeps twice until the second measure.
●A battery type signature at the time of the battery
consumption is shown.
LOW BATT blinks on and off when the battery is low.
●OLED will turn off after no operation for 1 minute.
