RQP Live Tutorial

Short videos to help you get started with Tapio RQP Live.

Getting started with RQP Live

Overview of the device, controls, and basic operation.

Tips

  • Use a USB-C Power Delivery 20V compatible charger for quick charging. With quick charging, the battery is charged from empty to full in 2 hours, giving over 12 hours of operating time.

Measuring Roll Hardness Profiles with Tapio RQP Live

Power on the device, create or select a folder, measure a profile, and view the results. Includes correct measurement technique.

Tips for accurate measurements

  • Wait until the hammer hitting has stabilized before moving the device
  • Make sure the device bottom has good contact on the roll and the device is not tilting.
  • Keep a steady measuring speed of approximately 15 cm/s
  • Stop moving at the roll end before lifting. By default, the device removes the last 15 knocks (0.5 seconds).
  • Always measure multiple profiles in a folder to ensure repeatability and to obtain more accurate mean profile statistics

Working with profiles and folders

Select profiles, view results, and manage folders directly on the device.

Tips

  • The Quick measure setting can be used to create a folder automatically when the device is pushed on a sample

Setting alert limits and device settings

Adjust alert limits and configure device settings from the device menu or by using the RQP Live Configurator.
Open the RQP Live Configurator from: https://tapio-measurement-technologies.github.io/rqp-configurator/

 

 

 Tips
  • The device clock can also be set with the RQP Live Configurator

Transferring data to PC with RollView

Transfer measurement data to your PC and explore it in Tapio RollView. The free RollView software is available for download at https://tapiotechnologies.com/downloads/

 

Tips
  • On sync, folders and profiles are transferred from the device to PC and the device is emptied.
  • The device clock is updated to match the PC clock when synchronizing with RollView
  • The standard postprocessors in RollView (creating Excel, JSON and image files) can be extended to create and transfer the profiles in any format.
  • Check the Advanced settings for analysis features such as adjustable filters, spectral analysis, exclude regions and highlight zones.

Glossary

Profile
A hardness profile measured along the roll width. A profile consists of hardness values measured at known distances.

Folder
A collection of profiles belonging to one roll. All profiles are stored in folders.

Mean profile
The average profile calculated from multiple profiles in a folder.

Mean profile statistics
Statistical values calculated from the mean profile, describing profile variation.

Hardness value
The measured value at a single position, based on measured hammer deceleration.
