Optional accessories

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.

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

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.

Getting started

Power supply

Power on
When the device is in standby mode, hit the “Power”-key to start the instrument and enter the main menu.

Note: The battery switch has to be set to “ON”.

Power off
When the device is switched on, hit the “Power”-key to put the device into standby mode.
Note: If the instrument is not used for a longer period of time, please set the battery switch to “OFF”.

Preparation

Check the battery voltage
Clean the workpiece surface that needs to be tested
Connect the sensor to the host with reference to the graphic below
Make sure that the instrument correctly placed on the workpiece surface that needs to be tested (figures below)
The sensor movement must be vertical to the tested surface (figure below)

If measurements are not performed the correct way, the sensor and the device may suffer damage.

Operation

Measurement

By hitting the “Start”-key the measurement will start in any menu item. The instrument will measure according to the current operation. After the measurement is finished, it will return to the main screen. If the measurement has to be cancelled, hit “Esc”-key

Further functions

Data management
When the instrument shows the main screen, hit “Menu”-key to enter main menu. Choose the submenu “Data”. If this is done the display shows the data management. Use the “Up” or “Down” keys to either choose “Test Data” or “Clear Data” and confirm your choice by hitting the “Enter”-key. The point “Test Data” shows the gathered measurement data. “Clear Data” will delete all
measurement data.

Check measurement data

The measurement data can be observed in two different ways:

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.
