6.5 Non-linearity

Most three-point tension meters employ only linear characterization and have large

errors at the midpoints (up to 15%). The Quick check uses multi-point segmenting to

correct for non-linearity, reducing it to less than 0.2%.

6.6 Wire Characteristics

Creep Every material including steel exhibits creep under load. It will neck down

over time, quite quickly over the first few seconds and much slower as time

progresses. A wire cable also sees creep from the wire spacing and wind.

This effect is seen as a display that drifts lower after it has been clamped

in line.

Variations Material that varies in diameter or shape will have different output at the

same tension

Strands The best cable assembly is one that is perfectly round, as it will not change

contact geometry with the wire twist. The closer the wire cable cross

section appears to be round, the better the measurement performance will

be.
