6 Achieving Best Accuracy
6.1 Accuracy
The Quick-Check is an instrument designed to give accuracy that typically exceeds
normal requirements for wire tensioning. You should have an understanding of what
factors affect tension measurement accuracy.
6.2 Calibration to Specific Wire Type
While it is best to have the instrument calibrated to the specific wire size(s) and type(s)
used, the Quick-check can often work adequately in other situations. If the best tension
accuracy is required, Dillon recommends that a calibration be performed for that
specific wire size and type.
Do not use the Quick-Check to measure tension for wires if either of the following are
true:
1. No wire calibrations are stored of the same diameter as the wire you are looking
to measure, and
2. You do not have sheaves of the same diameter.
If either of these conditions exist, contact your Dillon distributor.
Contact your Dillon distributor to improve accuracy for a specific wire type by calibrating
to it.
6.3 Loading Error
A tensiometer works by deflecting the cable, which makes the cable path longer than
when a tensiometer is not installed. When the tensiometer is removed, the wire tension
decreases as the cable length is restored. This effect is known as loading error. The
Quick-Check design elongates the cable by a mere 0.08 inch (2 mm), making loading
errors extremely small.
6.4 Non-repeatability
The Quick-Check’s sheave with bearing design provides the best mechanical
performance. It is also superior at detecting tension that is being added or removed.
Contact your Dillon distributor for any additional calibrations you may need.
