SECTION I INTRODUCTION AND DESCRIPTION INTRODUCTION - 1-1. This publication is issued as the basic Manual of Operation and Service Instructions for Types C8 and C9 Cable Tensiometers manufactured by OPTI Manufacturing Corp., Luquillo, Puerto Rico USA. The equipment covered are listed in table 1. Instructions contained in this publication apply to both types listed, unless specifically noted otherwise.
SECTION II SPECIAL SERVICE TOOLS SPECIAL SERVICE TOOLS 2-1. - No special tools are required for service or maintenance of the cable Tensiometer. SECTION III PREPARATION FOR USE, STORAGE, and SHIPMENT 3-1. PREPARATION FOR USE - The cable Tensiometer is shipped by the manufacturer in its own carrying case and is ready for use, for avoid damage on common use, the operator shall be use the Wrist Band adjustable, see figure 1.1.
4-2. OPERATING INSTRUCTIONS - Either the right- or left-hand may be used to operate this instrument. The handle latch retains the actuating handle. The latch is automatically released when the actuating handle is squeezed. To re-latch the actuating handle, the handle must be squeezed firmly against the side of the Tensiometer and the handle latch pushed up from the bottom against its spring load and held in the extended position while the actuating handle is slowly released against the handle latch.
4-4. TAKING CABLE TENSION READINGS, TYPE C8 a. Preset dial by rotating the knurled rim of the dial indicator until the pointer is directly over the line corresponding to the cable diameter.(See Figure 3a) SET POINTER DIRECTLY SET POINTER OVER CENTER OF LINE OVER CENTER OF WHEN READING TENSION LOADS LINE TO THE CABLE DIAMETER...
4-5. TAKING TENSION READINGS, TYPE C9 - The Type C9 cable Tensiometer is used in the same manner as the Type C8 with the following exception: the larger size cables have two rows of preset squares, one row identified by 250-, the other row identified by 250+. When measuring cable tensions below 250 pounds use corresponding squares in the row indicated by 250- and conversely, for the opposite condition, use 250+.(See Fig.
*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 readings at slightly different locations on the cable and average them. 4-8.
SECTION V PERIODIC INSPECTION, MAINTENANCE, AND LUBRICATION GENERAL - 5-1. No periodic inspection, maintenance, or lubrication is required for cable Tensiometers. As a matter of general practice, the instrument should be kept clean at all times. Particular attention should be paid to the two sectors and the riser block to see that they are always free from foreign matter.
SECTION VII CALIBRATION EQUIPMENT REQUIRED - 7-1. Calibrating the cable Tensiometer it will be necessary to have aircraft cables of various sizes and a method of accurately loading these cables with a range of loads from 10 to 450 pounds. DISASSEMBLY PRIOR TO CALIBRATION - 7-2.
Repeat steps i and j for 1/16” cable on Type C8 and 1/8” 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.
