User Manual

The following list shows the various sizes, types

and designations of messenger cables for which

the tools can be calibrated:

To obtain an accurate measurement it is imperative

that the strand to be measured be positively identi-

fied as to its actual diameter and its grade, either

Utilities Grade or Extra-High Strength. Secondly,

the Strand Tensionmeter to be used must have a

current calibration chart with a corresponding se-

rial number which has a calibration for the specific

strand you have identified.

The Tensionmeter measures the force required to

deflect the strand to an out-of-line position and

registers the amount of force required on the inte-

gral dial. The actual strand tension is then deter-

mined by referring to the calibration chart specifi-

cally prepared for and furnished with each Ten-

sionmeter, which converts the dial indicator read-

ing into the actual tension value.

The instrument measures tension in pounds force

to within an accuracy of three percent (± 3%) or ±

150 pounds, whichever is greater.
