7.0 HOW TO CHECK ACCURACY:

To verify the accuracy of your instrument, simulate a tension load on your strapping by suspending known weights

to a sample length of the material. Then verify these values with the instrument, i.e.: if a 100 lbs weight is freely

CF 124 1/19/12

suspended from a single length of strapping, the strap is now tensioned to 100 lbs, and your instrument should

indicate 100 lbs on the display when properly engaged to the material. To correctly obtain readings, first zero your

instrument in the attitude it will be used for testing, then engage the instrument to the tensioned strapping and note

the reading. When performing this test make certain your strapping thickness is dimensionally within tolerance (+/-

.003” of size), and not out of tolerance.

KEEP IT SIMPLE. Only simulate tensions using free-hanging weights on correctly-sized strapping material. Never

use any device that attempts to convert rotational torque values into tension loads, as these types of systems are

highly inaccurate.

When calibrating instruments use lb weights values only. (For optimum accuracy use weights traceable to

National Standards.)

Custom Calibrations for the STX-Series of Digital Tension Meters

The Calibration feature is password protected. In order to per-form a Custom Calibration a series

of key inputs are required. Warning: This procedure will erase previous calibration data. Only a

qualified testing laboratory with traceable weights and standards should perform a calibration.

Figure 1, Simulating Strap Tension

PERFORMING A 5-POINT, MULTILINERIZATION CALIBRATION

(If you only need to verify that the calibration you’ve selected is accurate, go to the “How To Check Accuracy”

section.)

Step 1: From the Main Display press ↑or ↓arrows until you reach Setup. Press ENTER. Press the ↓arrow button

until you reach Cal Tension. Press ENTER. The screen will display: Setup, Calibrate Tension, Enter Password.

Press the ENTER button once, the ↑arrow button once and the ENTER button once more. (These three inputs are

the password.) Now the screen will display Setup, Calibrate Tension and you will be able to scroll down the list to

select the description that you want to use for the new calibration. When this new description is highlighted, press

ENTER.

Step 2: Next you will be prompted ENTER WEIGHT 1. Using the ↑and ↓arrows select a minimum tension value

(do not use zero). Press ENTER. Select increasing weight values for WEIGHT 2 THRU 4 (No. 4 being the

maximum weight value). At each weight number select your weight value using the ↑and ↓arrows. ENTER each

selection. Next you will calibrate the instrument to the weight values you just selected. (To simulate tension loads

for calibration, take a sample length of your material and suspend it from above. Next hang weights from your

material in the weight values you previously selected in “enter weights 1 through 4”.)

Your instrument will now prompt you PLACE WEIGHT 0. With zero tension applied to the instrument press ENTER.

Next you will be prompted PLACE WEIGHT 1. Suspend the exact weight value from your material that you

previously selected. Engage instrument to the tensioned material and then press ENTER. Next suspend weight

value 2 from your material, engage the instrument to your tensioned material and press ENTER. Repeat procedure

for steps 3 and 4. Once you have entered the value for WEIGHT 4 you have finished the calibration and will be

returned to the Main Display. Your main display will now indicate the description of the calibration you’ve just

entered. This indicates you have now selected the calibration you just performed. To change calibration use the ↑

or ↓arrows until you reach SELECT MATERIAL. Follow procedures outlined in Section 3.5.
