About the installation tension level of our tooth belt, the gap will not occur between U-508 measurement and true tension in the range of Note1 and Note3. So it is not necessary to set a tension compensating rate. Note1） As for the measuring installation tension, set the belt on the machine ﬁrst and measure the average tension of stretch and loose side of the belt after spinning several times to make the machine run smoothly.
Page 15 Thank you for choosing our sonic tension meter (U-508). We guarantee for one year for the main body and six months for the sensor. If our sonic tension meter (U-508) fails due to a manufacturing or workmanship defect during the period, we repair it free of charge.
