”
cable on Type C9, to improve indicator
accuracy to +/- 5 % (If closest possible accuracy is desired take three to five reading at slightly
different locations on the cable and average them). On step
j
for 1/16” & 1/8” cable
on Type C8 the
low end is 10 lbs. and the desired indicator read between 9-15. Do not remove the 0.010 inch
shims from the top of the frame pins. After this, the unit shall make linearity for all cables and
tension ranges.
m.
Replace cover (2) and secure with screws (1).
n.
Preset the indicator dial to the smallest cable size. Measure the load required to deflect the
calibration bar. Remove the load marked on the identification tab and mark the new value
indicated on the Tensiometer.
Note: Due principally to the uneven surface of the stranded cables, slight variations in readings may occur on the
same cable at the same tension. If closest possible accuracy is desired take three or five reading at slightly
different locations on the test area of the cable and average them. It is considered a unit to be ‘out of calibration’
when the average reading is more than ± 5% of indicator or one minor division whichever is greater.

INDICATOR CABLE SIZE
-
To re-establish the accuracy of the indicator cable size , proceed as
follows:
a.
Remove existing mark on center pin washer (17) with a fine file.
b.
With handle in locked position, rotate indicator cable size (16) counterclockwise until it contacts
stop on handle assembly (19). See figure 2 for reference.
c.
For C8 model, set at 100 lbs. on cable 1/16, for C9 model, set at 150 lbs. on cable 1/8, clamp the
Tensiometer on a cable.
d.
Return handle to lock position.
Note: In next step, do not move the indicator cable size (16).
e.
Mark center pin washer (17) with a scribe opposite on known diameter (1/16 or 1/8) on indicator
cable size.
