The Horizontal shaft alignment app is designed to be used with the SKF Shaft Alignment Tool TKSA 51 or TKSA 71. Together, the hardware and the app form an alignment system that allows shaft alignments of many rotating machines to be made in an intuitive and easy way. The system uses line laser to PSD technology that enables highly accurate and reliable shaft alignments. The hardware and its app communicate wirelessly via Bluetooth®. Without the hardware the app can nonetheless be used, as it features a fully functional demonstration mode allowing the complete alignment process to be experienced before purchasing the TKSA 51 or TKSA 71 instrument.

 KEY FEATURES:
 • Very easy-to-use – The Horizontal shaft alignment app focuses on making the main alignment tasks as easy as possible and enabling accurate shaft alignments.

 • Demonstration mode – The Horizontal shaft alignment app offers a fully functional demonstration mode allowing the complete alignment process to be experienced before purchasing a supported SKF Shaft Alignment Tool.

 • Automatic alignment report – Automatically generated alignment reports give a complete overview of the alignment process and results. The reports can be customised with additional notes, a machine picture, a signature and can easily be shared via email or cloud services.

 • Explanatory videos – Easy to follow videos demonstrating how to set up and perform accurate measurements using the TKSA 51 or TKSA 71.

 • 3D Animations – 3D animations guide the user through the alignment process, allowing accurate shaft alignment to be performed in a very easy way.

 • Machine library and QR code scanner – Helps keeping track of the machines that have been measured. Machine information like distances, the machine picture, and other details are saved for each machine and can be reused the next time the same machine is measured. QR codes can be scanned to identify a machine and quickly retrieve its details. The library can also be used for easy access to all the reports generated for each machine in one place. HARDWARE – SKF Shaft Alignment Tool TKSA 51 and TKSA 71:

In creating its first connected chronograph, Breitling applied a new philosophy that places the smartphone at the service of the watch, in order to increase its functionality and user-friendliness. Two-way communication makes the two instruments a perfectly complementary tandem in which each one is used for that which it does best. The EXOSPACE application allows the user to verify and adjust the main settings of the EXOSPACE B55 chronograph at a glance, but also to have rapid access to its different functions. The smartphone memory allows the different measurements of the EXOSPACE B55 chronograph to be saved so that they can be viewed, compared or even transferred to other applications. The smartphone screen offers unparalleled reading comfort, thus giving stored data a new dimension. • Verify the state of your chronograph at just a glance and adjust your settings (UTC time, timezones, date, 7 alarms, synchronization of the hands, display. • Store different time series (Lap Timer / Chrono Add) to compare them on your smartphone. View your different times and simply export them. Use the watch tachymeter to measure your average speed. • Configure the different chronograph functions such as Timer, Countdown/Countup, Chrono Add, Chrono Flight. • Access flight times (Chrono Flight), view the relevant information at a glance and save them for further consultation. • Enter easily the take-off and landing airports for your flight times. • Export your flight times to another application or to your personal computer. • Configure your watch to receive notifications from your smartphone; the watch can vibrate and/or ring when a call, message, email or appointment alert is received. • Personalize the display on the watch according to your profile (Sport / Pilot). • Update the software of your watch directly from the application.
