ezSCOPE
ezSCOPE is a visualization tool for ezABSO.
By connecting ezSCOPE to ezABSO, the data in the sensor is imported into the PC.
The recorded data can be displayed as graphics (absolute position, speed, vibration) and data values (numerical value) on the PC monitor. ezSCOPE also has a data storage capability.
* Data can be transmitted by infrared rays to the ezSCOPE main unit using the optional infrared transmission module.

Connection example
Vibration Data - Easy Diagnosis - NEW
Integrating a vibration sensor IC into the ezABSO installs a new function for measuring and monitoring the vibration applied to the main body from the outside.
With this function, it is possible to measure the vibration exerted on the engine with ezABSO. *1
Please use it for easy diagnosis of connected devices as one of the data collected by IIoT.
*1: Only when ezABSO is installed integrally with the engine (see figure above).
