How to Use a Tensionmeter
Before you use the Penn-Tech Cable Tensionmeter to measure a cable's tension:
- Identify the cable you're measuring by diameter and type.
- Check your calibration chart* to see:
a. Which accessory saddle you need for the cable you're measuring, if any.
b. Which handle position to use—1, 2, 3, or 4.
3. Secure the accessory saddle to the built-in saddle

Taking Measurements
- Select a cable section for your measurement that is:
a. Free of damage from cable grips (pork chops), clamps, or expanding corrosion.
b. At least 1 foot from the cable termination. - Use the hooks on either end of the Tensionmeter to suspend it on the cable with the dial indicator toward the low end of the cable.
- Check the dial to make sure idicator needle points at zero. If it doesn't, loosen the slotted screw recessed in the dial case, use your thumbs to move the dial until it points to zero, and tighten the screw
4. Pull down the handle. As the handle seats into the
intended position, the bottom edge of the saddle will lift up and deflect against the cable.
5. Record the dial measurement. The dial indicator reads from 0 to 100. If a high-load measurement causes the dial to pass zero, add 100 to the dial reading.
6. Take 3 or more readings at least 6 inches apart, noting the dial reading for each. Average your readings. Find the value of the average reading on the calibration chart to determine the cable tension.

CAUTION: Be sure to use the Tensionmeter on cables ONLY for the specific construction, breaking strength, and size for which the unit is calibrated. Be certain to use the correct handle position and / or accessory saddle when taking measurements. Incorrect handle position and accessory saddle will result in false readings, possible over-tensioning, and damage to the Tensionmeter. Over-tensioning guy cables is dangerous to personnel and can be damaging to structures.
