5. READING OF TENSION. Variations in materials and sizes affect tension readings. It is essential to select the
correct material and size from the calibration menu before use, or values may be incorrect.
6. SELECT MATERIAL. From the Main Display (first screen seen when unit is turned on) use the ↑ or ↓ keys until
SELECT MATERIAL is displayed. Press ENTER. Next toggle through the various selections using the ↑ or ↓
arrows until correct cable size is highlighted, and press ENTER to make your selection. If your specific material
is not listed, follow the calibration instructions included at the end of these instructions, or send a sample and
the instrument to Cooper Instruments for a custom calibration.
7. SELECTING TENSION UNITS IN LBS, KILOGRAMS or NEWTONS. Press the ↑ or ↓ keys until TENSION
UNITS is displayed. Press ENTER. Next, select: Lbs, Kilograms or NEWTONS and ENTER selection.
8. ENGAGE INSTRUMENT TO TENSIONED MATERIAL. For best accuracy hold the instrument in the attitude
the measurement will be taken in and press ZERO. Push “closure bar” away from the instrument handle to
raise the outer cable guides. Engage the tensioned material by routing the cable so that it falls under the outer
cable guides and over the center, contact point. Squeeze the “closure bar” shut until it locks into position beside
the handle, and note the tension reading.
