6.0 Troubleshooting ..................................................................................................................16

Most three-point tension meters employ only linear characterization and

have large errors at the midpoints (up to 15%). The CTM uses multi-point

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

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

neck down over time, quite quickly over the ﬁ rst 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.

5.5 Non-linearity

5.6 Wire Characteristics

Problem Possible Cause Solution

Powers on momen-

tarily and turns off

Low battery Replace with high quality alka-

line batteries

Does not power on Low battery Replace with high quality alka-

line batteries

Batteries installed

backwards or no

spring contact

Insure that positive terminals

of both batteries (nub) face in-

ward – towards the black cap.

Check that spring is attached

to the battery cap.

Software reset Remove battery cap & reinstall

after one minute. Attempt to

turn power on again.

Display contrast too

light

Hold the Right Arrow key down

while pressing the F2 key

several times to increase the

display contrast. If nothing oc-

curs, release both keys. Press

the power button and try again.

Display is

completely dark

Display contrast too

dark

Hold the Arrow key down while

pressing the F1 key several

times to decrease the display

contrast.

Display drifts down-

ward once installed

Wire material is

creeping and inter-

nal friction between

wires is relieved.

This is normal behavior of

wire. Lower display resolution

to mask this effect.

Temperature not

accurate

Instrument changed

temperature envi-

ronments

Allow instrument to remain in

environment until temp stabi-

lizes or enter temp manually

Instrument exposed

to sun

Enter temp manually
