6 4. INSTRUMENT FEATURES Calibratin and Accuracy WX-1 series instruments are calibrated t custmer-supplied materials t ensure the greatest pssible accuracy fr each applicatin. When rdering, please prvide Tensitrn with a sample (apprximately 10 -wide, 10 -lng) f each material yu d like included in the menu. WX-1 meters display tensin per 10 width f material. Readings that equal PLI can be prvided instead, but the accuracy f each reading will be reduced. Accuracy is material-specific. Typical accuracy fr WX-1 instruments is summarized in the table belw, but actual accuracy may differ, depending n the prperties f the material used in the calibratin: Mdel Typical WX-1 Accuracy Reslutin Range (lb) (lb) Full-Scale Accuracy WX % WX % WX % WX % Add-On Optins Instruments can be cnfigured with either f these ptins: - A Analg Output ptin Data utput at 40 Hz. 0-5 VDC r 4-20 ma with Sftware-definable ending sequences.

T verify the accuracy f yur instrument, check the tensin n a sample length f web by suspending knwn weights frm the ppsite end. 2. When perfrming this test, use a micrmeter t measure yur web thickness and ensure it is dimensinally within tlerance. 3. Only use free-hanging weights which are traceable t Natinal Standards n crrectly-sized webs. (See Figure 7.) 4. Never use any tensining device that attempts t cnvert rtatinal trque values int tensin lads, as these types f systems are highly inaccurate. Als, any lad cell system must be rutinely checked fr accuracy using traceable weights as these types f systems are als highly inaccurate WX-1 Series Instrument Revised: pg. 12

13 and generally d nt meet the minimum repeatable accuracy standards required by ISO Check Accuracy 1. Cnfirm that the size web yu re wrking with is the same as the ne selected in yur WX s display. 2. Befre engaging the WX-1 instrument nt the web, zer the instrument by hlding it in the same attitude yu ll be taking the readings and press the Enter r Zer buttn. This will eliminate any small tare effects. 3. Take readings alng the web. FOR BEST RESULTS ALWAYS TAKE SEVERAL READINGS OF THE WEB TENSION BY DISENGAGING AND THEN RE-ENGAGING THE INSTRUMENT FROM THE WEB ITSELF. 4. Verify the tensin value. Fr example, if yur suspended weight is 40.0 lb. yur instrument shuld als indicate 40.0 lb. +/- the full-scale accuracy percentage f the specific instrument mdel listed in Sectin 4, nce prperly engaged t the web. This prcedure cnfirms the instrument s accuracy and it is nw ready fr use. Nte: Accuracy Specificatin: NOTE, ACCURACY IS MODEL DEPENDENT. Fr an instrument with a full-scale range f 250 lb., this translates int +/- 5 lb., and fr an instrument with a full-scale range f 500 lb., accuracy is +/ lb. (with a 2% Accuracy Specificatin). If yu have additinal questins, please cntact Tensitrn fr 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 yu want t verify r check the accuracy f a Web g t: Check Accuracy in Sectin 7: Advanced Operatin. When calibrating these instruments tensin values must be entered in Lbs. Nte: If yur dead weight standards are in Kilgrams, cnvert their values int Lbs: 1 KG = Lbs WX-1 Series Instrument Revised: pg. 13

14 Figure 7: Free hanging weight simulating web tensin. Fllw these instructins t update the calibratin fr an existing web n the menu r t add a calibratin fr a new web. If yu wuld like t add a new web, first create a name fr it by fllwing the instructins under Custm Names in Sectin 6, abve. 1. Scrll t SETUP and press ENTER. Next, scrll t RE-CAL TENSION and press ENTER. The screen will nw display: SETUP, RE-CALIBRATE TENSION, ENTER PASSWORD, CAL DATA WILL BE LOST! 2. Enter Passwrd. Cntact Tensitrn at service@tensitrn.cm fr the passwrd. 3. The display nw indicates: SETUP RE-CALIBRATE TENSION with a list f the calibratin names and custm names prgrammed int the instrument. Scrll t the descriptin yu wish t recalibrate, highlight it and then press ENTER. 4. The next screen will indicate: CALIBRATE TENSION, NUMBER OF POINTS. Using the up and dwn arrws select the number f calibratin pints t which yu will be tensining the web. The minimum is 5 pints. Zer is a calibratin pint already set, s yu will need t define a minimum f 4 increasing tensin values such as: 50, 100, 150 and 200. If desired yu can define mre than 5 weight pints, with a maximum f 10 pints ttal. If 10 calibratin pints were selected the entries culd lk smething like this: 10, 20, 30, 40, 50, 60, 70, 80, 90. WX-1 Series Instrument Revised: pg. 14

15 5. ENTER WEIGHT. After selecting the number f calibratin pints, yu need t define these weight values. Using the up r dwn arrws select yur first tensin, r weight calibratin pint and press ENTER. D nt use 0 (zer) as this value is already prgrammed int the instrument. Next, use the up r dwn arrws t select yur weight 2 value, making sure the value entered is greater than the entry in weight 1. Next, select increasing weight values fr the additinal weight pints, withut exceeding the maximum tensin range f the instrument. 6. CALIBRATE TENSION. Next yu will calibrate the instrument using the weight values yu previusly selected. T prperly simulate these tensins, suspend a single length f yur web frm abve and suspend knwn weights nt the web in the values yu ve previusly selected, when prmpted. (See Figure 7.) a. CALIBRATE TENSION, NUMBER OF POINTS, ZERO UNIT. Withut any web engaged t the instrument, hld it in the attitude yu will be taking the reading in and press ENTER t calibrate zer weight. Next the display will prmpt yu t suspend the weight value yu previusly selected in step 5. If, fr example yu selected 50 lb. fr yur first weight value the instrument will indicate: PLACE WEIGHT 50. b. Suspend the exact weight value frm yur web that yu ve previusly selected (In this example it wuld be 50 lb.) c. Next, engage the instrument t yur tensined web, then press ENTER nce the reading has stabilized. d. Repeat steps b. and c. fr the remaining weight pints by suspending additinal weights nt yur web in the values previusly selected and entering these readings. e. Once the last weight value is entered, the instrument will return t the SETUP menu. Press the ESCAPE buttn t return t the main display. f. The main display will nw indicate the web/material descriptin yu just finished calibrating. If the material name n the display is nt the material yu just recalibrated, yu have reprgrammed the incrrect descriptin. If this happens, yu will need t recalibrate bth the material indicated n the display alng with the material yu thught yu were calibrating. g. After cmpleting a calibratin always recheck the values.
