Page 7: Scanning Bars
The bar has been divided by the middle and provided with drill holes then filled with lead. This method is used frequently to fake silver bars using lead-tin alloys. Preparation of measurement: Calibrating the BarScreenSensor The first step consists of the calibration of the measurement unit by using the included stainless steel measurement plate. - Page 8 The next step is measuring the bar’s thickness at the spot you want to test by using calipers. Over its complete length, our bar has a thickness of 20 mm. In case of bars of unusual forms, you might have to measure the thickness of various spots. Now you can carry out the actual ultrasound measurement.
- Page 9 After this, you should „scan“ the bar. To do so, you lay the measurement head on different spots to exclude inclusions of foreign material. In case of a fake, the value of the thickness can differ significantly. Measurement 2: Examination of UNKNOWN sound speeds There are several situations where the sound speed is not exactly known.
- Page 10 Of course, this value is incorrect because the previously selected sound speed is wrong. This is why you now take off the measurement head from the bar and measure the objects thickness with calipers. Use the arrow keys to adjust the thickness for the BarScreenSensor in a way that it matches with the actual thickness.
- Page 11 As a last step, you press the VEL-button once again. The device then calculates the correct speed of sound. Having done this, you can scan the rest of the bar like you did in measurement 1. Saving the data The established value can now be saved on the device’s memory. In order to do so, push STORE for 2 seconds to get to the save mode.

6. Tips & Tricks Surface quality Surfaces which are too rough will cause measurement errors. Please only use smooth and plane surfaces for the investigation. In case of bars, please do not adapt the measuring head on the hallmark but on the smooth area of the bar. Non-parallel surface The contact area should be parallel to the opposite side in order to avoid wrong measured values. -
