For technicians
The service of stationary probes has never been easier. After connecting the probe, it is possible to perform its diagnostics or calibration using only the interface and a mobile phone.
Calibration protocols in PDF format can be sent separately or in bulk, after completing the service intervention.
A number of software features, such as a calibration guide or the restoration of factory settings, enable the identification and removal of most issues caused by previous unprofessional interventions.
There is no longer a need to share a single handheld device among multiple technicians and worry about its readiness for use.
