Page 9: Stvi Introduction
The STVI is a user friendly interface to control the Megger SPI test equipment. This manual contains the information that you will need in order to set up and use your STVI with the SPI Device. How the unit operates, some of the different types of testing you can do, and how to save and view your test results with the Smart Touch View Interface software is described. -
Page 10: Terminology
5. USB Interface – the USB port is used to update the firmware in the SPI as well as update the software in the STVI using a USB memory stick. It may also be used to download test results from the STVI for download into another PC with Power DB software for storage or printing. For control of the SPI, an Ethernet cable is provided. -

A numerical value associated with the highest current at rated voltage that the device can interrupt without external damage. Power Over Ethernet Input Power The STVI gets Power Over Ethernet (PoE) of 48 Volts DC at 0.5 A from the SPI STVI port. SETUP Unpack System Unpack the unit and check for evidence of any shipping damage. -
Page 12: Ethernet Port
2.2.1 Ethernet Port There is one Ethernet port on the STVI for connecting to the SPI unit. Connect the STVI to the SPI unit using the port labeled STVI (as shown in Figure 3). Figure 3 - STVI port on the SPI 2.2.2... -
Page 13: Smart Touch View Interface
Smart Touch View Interface The STVI is the manual control and user interface for the unit. All manual entries will be made through the STVI unless the unit is connected to a personal computer. During the power up sequence the test system automatically does a self-test to insure everything is operating properly. - Page 14 The PC version will then display the Instrument Configuration screen as shown in Figure 6. Click the OK button and the software will attempt to auto detect an instrument and connect. If no instrument is detected due to firewall, VPN settings or an incorrect IP address the user will need to take appropriate corrective action.
