General Calibration Precautions
1. To verify the accuracy of your instrument, check the tension on a sample
length of web by suspending known weights from the opposite end.
2. When performing this test, use a micrometer to measure your web
thickness and ensure it is dimensionally within tolerance.
3. Only use free-hanging weights which are traceable to National Standards
on correctly-sized webs. (See Figure 7.)
4. Never use any tensioning device that attempts to convert rotational torque
values into tension loads, as these types of systems are highly inaccurate.
Also, any load cell system must be routinely checked for accuracy using
traceable weights as these types of systems are also highly inaccurate
and generally do not meet the minimum repeatable accuracy standards
required by ISO-17025.
