To verify the accuracy of your instrument, check the tension on a sample length of band by suspending known weights from the opposite end. 2. When performing this test, use a micrometer to measure your band thickness and ensure it is dimensionally within tolerance. 3. Only use free-hanging weights which are traceable to National Standards on correctly-sized bands. (See Figure 7.) 4. Never use any tensioning device that attempts to convert rotational torque values into tension loads, as these types of systems are highly inaccurate. BTX-1 Series Instrument Revised: 3.14.2018 www.tensitron.com pg. 12

Also, any load cell system must be routinely checked for accuracy using traceable weights as these types of systems are also highly inaccurate and generally do not meet the minimum repeatable accuracy standards required by ISO-17025. Check Accuracy 1. Confirm that the size band you re working with is the same as the one selected in your BTX s display. 2. Before engaging the BTX-1 instrument onto the band, zero the instrument by holding it in the same attitude you ll be taking the readings and press the Enter or Zero button. This will eliminate any small tare effects. 3. Take readings along the band. FOR BEST RESULTS ALWAYS TAKE SEVERAL READINGS OF THE BAND TENSION BY DISENGAGING AND THEN RE-ENGAGING THE INSTRUMENT FROM THE BAND ITSELF. 4. Verify the tension value. For example, if your suspended weight is 40.0 lb. your instrument should also indicate 40.0 lb. +/- the full-scale accuracy percentage of the specific instrument model listed in Section 4, once properly engaged to the band. This procedure confirms the instrument s accuracy and it is now ready for use. Note: Accuracy Specification: NOTE, ACCURACY IS MODEL DEPENDENT. For an instrument with a full-scale range of 250 lb., this translates into +/- 5 lb., and for an instrument with a full-scale range of 500 lb., accuracy is +/- 10.0 lb. (with a 2% Accuracy Specification). If you have additional questions, please contact Tensitron for help. Calibrate Instrument *IMPORTANT: THIS FEATURE SHOULD ONLY BE USED BY A CALIBRATION FACILITY USING CERTIFIED AND TRACEABLE DEAD WEIGHTS. DO NOT USE THIS FEATURE FOR A SIMPLE ACCURACY CHECK. If you want to verify or check the accuracy of a calibration go to: Check Accuracy in Section 7: Advanced Operation. When calibrating these instruments tension values must be entered in Lbs. Note: If your dead weight standards are in Kilograms, convert their values into Lbs: 1 KG = 2.2046 Lbs BTX-1 Series Instrument Revised: 3.14.2018 www.tensitron.com pg. 13

Figure 7: Free hanging weight simulating band tension. Follow these instructions to update the calibration for an existing band on the menu or to add a calibration for a new band. If you would like to add a new band, first create a name for it by following the instructions under Custom Names in Section 6, above. 1. Scroll to SETUP and press ENTER. Next, scroll to RE-CAL TENSION and press ENTER. The screen will now display: SETUP, RE-CALIBRATE TENSION, ENTER PASSWORD, CAL DATA WILL BE LOST! 2. Enter Password. Contact Tensitron at service@tensitron.com for the password. 3. The display now indicates: SETUP RE-CALIBRATE TENSION with a list of the calibration names and custom names programmed into the instrument. Scroll to the description you wish to recalibrate, highlight it and then press ENTER. 4. The next screen will indicate: CALIBRATE TENSION, NUMBER OF POINTS. Using the up and down arrows select the number of calibration points to which you will be tensioning the band. The minimum is 5 points. Zero is a calibration point already set, so you will need to define a minimum of 4 increasing tension values such as: 50, 100, 150 and 200. If desired you can define more than 5 weight points, with a maximum of 10 points total. If 10 calibration points were selected the entries could look something like this: 10, 20, 30, 40, 50, 60, 70, 80, 90. BTX-1 Series Instrument Revised: 3.14.2018 www.tensitron.com pg. 14

5. ENTER WEIGHT. After selecting the number of calibration points, you need to define these weight values. Using the up or down arrows select your first tension, or weight calibration point and press ENTER. Do not use 0 (zero) as this value is already programmed into the instrument. Next, use the up or down arrows to select your weight 2 value, making sure the value entered is greater than the entry in weight 1. Next, select increasing weight values for the additional weight points, without exceeding the maximum tension range of the instrument. 6. CALIBRATE TENSION. Next you will calibrate the instrument using the weight values you previously selected. To properly simulate these tensions, suspend a single length of your band from above and suspend known weights onto the band in the values you ve previously selected, when prompted. (See Figure 7.) a. CALIBRATE TENSION, NUMBER OF POINTS, ZERO UNIT. Without any band engaged to the instrument, hold it in the attitude you will be taking the reading in and press ENTER to calibrate zero weight. Next the display will prompt you to suspend the weight value you previously selected in step 5. If, for example you selected 50 lb. for your first weight value the instrument will indicate: PLACE WEIGHT 50. b. Suspend the exact weight value from your band that you ve previously selected (In this example it would be 50 lb.) c. Next, engage the instrument to your tensioned band, then press ENTER once the reading has stabilized. d. Repeat steps b. and c. for the remaining weight points by suspending additional weights onto your band in the values previously selected and entering these readings. e. Once the last weight value is entered, the instrument will return to the SETUP menu. Press the ESCAPE button to return to the main display. f. The main display will now indicate the band/material description you just finished calibrating. If the material name on the display is not the material you just recalibrated, you have reprogrammed the incorrect description. If this happens, you will need to recalibrate both the material indicated on the display along with the material you thought you were calibrating. g. After completing a calibration always recheck the values. Refer to Check Accuracy in Section 7. BTX-1 Series Instrument Revised: 3.14.2018 www.tensitron.com pg. 15
