OVERVIEW
The CHECK•LINE® DTMB and DTMX Digital Tension Meters are factory calibrated using the materials listed in the Calibrationsection of the Operating Instruction Guide. The DTMB models are factory calibrated using two monofilament samples with different diameters, and the DTMX models are calibrated with two monofilamentsamples and two bare copper wire samples. A Special Calibration can be easily performed by the user using a customer supplied sample of the process material to obtain the highest accuracy in specificapplications. DTMB and DTMX models are calibrated using three (3) calibration points, normally at 20%, 50% and 100% of the full scale tension range of the instrument. These “calibration points” can beadjusted up or down in 10% increments to “fine-tune” the calibration if desired. During the calibration procedure, the user will be prompted to suspend a series of known weights equal to the displayedpercentages. The calibration steps are first performed for the “thin” sample (smaller diameter) and then repeated for the “thick” sample (larger diameter). The weights suspended from the process...
