NOTE
Do not attempt to take cable tension readings with pointer lock
button pressed. This button should only be used to lock dial
indicator pointer when taking readings on closely grouped or in
awkward or blind locations. When this occurs, button must be
pressed to unlock pointer after each reading; otherwise,
erroneous readings will be obtained.
(6) TI will indicate between 23.75 and 26.25 pounds.
(7) Reading on TI cable size-gage must correspond with cable size stamped on cable
terminal.
(8) Repeat (1) through (7) above, using cables and total weight listed in table 4. TI
will indicate within limits specified.

NOTE
Due to the uneven surface of stranded cables a slight variation
in reading will sometimes occur on the same cable at the same
tension. This is especially true of 5/32-inch diameter cable and
larger. To obtain the greatest possible accuracy three to five
readings should be taken at slightly different (approximately 1
inch) locations on the cable. Average these readings to obtain
the maximum degree of accuracy.
(9) Repeat (1) through (7) above, using cables and total weight as listed in table 4.
TI will indicate within limits specified.
NOTE
When measuring tensions, using the 7/32 and 1/4-inch size
cables, set the dial to [125-] square for tensions of 125 pounds
and below and [125+] square for tensions above 125 pounds.
b. Adjustments. No adjustments can be made.
