2.4 Optional accessories

2.4.1 Measurement platform

Use the measurement platform to easily adjust the position between the instrument and the
workpiece to be measured. This ensures a more flexible and stable operation and creates a bigger
use scope and measures the roughness on the surface of complex shape parts. When the
platform is used the needle position can be adjusted more precisely and it measures more
smoothly. It is suggested to use the platform when the Ra value is expected to be small.

2.4.2 Extension bar

Use the extension bar to increase the sensor depth of the workpiece inside. The length of the
extension bar is 50 mm.

3 System description

The roughness tester is suitable for laboratories and the production field. It is able to measure a
variety of surface roughness of machined parts. Furthermore it can calculate the corresponding
parameters according to the selected measurement conditions and in addition to that the
measurement results are clearly shown on the OLED display as tables and graphics.

9 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.

If you have any questions, please contact PCE Instruments.
