As for installation tension of our toothed belt, no difference is generated between the measured value of U-507 and actual
tension in the measurement range of note 1) - 3) below, and it is not necessary to set any tension correction factor.
Note 1) In measuring the installation tension, basically set the belt on the machine and turn it several times to make the machine
familiar, and measure the tension of 2 spans on belt tension side and loosening side and take the average. When tension of 2
spans is different more than 30% approx, adjust them almost equal and measure again.
Note 2) Measure with a span having the length more than 20 times the tooth pitch.
(Because a value higher than actual tension is displayed when the span is so short as to be affected by rigidity of belt itself.)
Note 3) Set the tension range more than 1/3 of standard installation tension.
(Because a value higher than actual tension is displayed when the tension is so low as to be affected by rigidity of belt itself.)
Measurement in an extremely low tension range is sometimes impossible as is seen from the measurement principle of this
tension meter.
Note 4) It is reasonably estimated that some difference from actual tension is generated as for special belt such as wide belt for
transport and back-ribbed belt, so that simple calibration is required for checking tension which needs precision comparatively.
As for experienced machine, install the belt by a procedure provided for corresponding machine, certify the frequency with
U-507 tension meter, and set the same frequency thereafter, thus controlling the tension.
