- Page 26 The graphic representation of the type of base, is also indicative of the base condition. When dirt, corrosion and or other surface irregularities are present on the base material, the graphic will turn less uniform. Sharper “teeth” mean less uniformity of the base material. Figure 2.9: Base material condition indicator On figure 2.8, “...
- Page 27 After the base calibration procedure is concluded, the unit will ask you to measure using a shim of a known thickness. For the calibration modes that do not require base calibration (1 point, 2 point and Swedish), the calibration process begins here. Follow the on-screen instructions and measure the shim of a known thickness value over the base.
- Page 28 For the methods above, the unit will activate the thickness measurement editor only when the required number of samples have been taken. Use the arrow keys to adjust the thickness to the nominal shim value and touch save. Figure 2.12: Shim calibration thickness adjustment screen With short touches on the key, preset calibration shim values can be loaded.
- Page 29 Note The order in which you use the shims (Shim 1 and Shim 2) based on their thickness is irrelevant. Tips Better results with these calibration methods are obtained using shims with lower and higher thickness values than the actual lowest and highest measurements that you will be taking.
- Page 30 To exit the calibration memory menu touch Important In order to obtain better results with your QC5, calibrate using a the test piece that you are actually going to measure or use a test piece sample that is in the same condition.
- Page 31 The QC5 allows you to increase or decrease a value (offset) to adjust for errors produced by surface irregularities.
