NOVOTEST.ED.Т-UD3.000 OMOperation ManualHardness Tester NOVOTEST T-UD3Page. 13This method is suitable for hardness measurements on products of various weight and thickness,and especially on finished products with a glossy surface, since it leaves a minimally visible imprintafter measurements.The design of the ultrasonic probe makes it possible to carry out measurements in hard-to-reachplaces (for example, the surface of gear teeth, etc.), as well as on thin-walled structures (eg. pipelines,etc.) that can not be measured dynamically by the probe.It should be taken into account that the result of the measurement by the UCI method depends onthe Young's modulus of the tested product.1.7 Means of measurement, tools and accessoriesThe efficiency of the device is evaluated by checking the measurement of hardness on thereference hardness test blocks, reference hardness blocks should be grounded to the grinding plateweighing not less than 5 kg through a layer of grease. Mismatch readings must not exceed thepermissible error (Table. 1.2). If the permissible error is exceeded, calibrate the instrument inaccordance with 2.3.7.The manufacturer should make adjustment and tuning of the device in the case of faults.1.8 Marking and sealingOn the front panel of the device is a symbol of the device with the trademark of the manufacturer.On the rear panel, under the battery compartment cover the serial number is printed.1.9 PackingThe electronic unit and the probe are delivered in a package (case), excluding their damage duringtransportation.To avoid mechanical damage to the cable and connectors of the device, it is necessary todisconnect the sensor from the device before packing it into the package.
