following: 1. Drawing: unit, battery and charger Make sure you have the appropriate probes, wedges, and encoder for the type of inspection you intend to perform. You may also use the Prisma demo kit, which includes a basic set of accessories necessary to complete the scenarios described in this document. V1.1 5 2 Inserting and charging the battery for the first time 2. Drawing: unit back Unscrew the back door and insert the battery. Remove the waterproof rubber cover over the AC input socket and connect the AC power adaptor. Before using it for the first time, the battery must be charged for at least 6 hours; however, the unit can be used while charging. An optional external battery charger and additional battery packs can be added in order to reduce down- time and increase productivity. V1.1 6 3 Booting the unit The following is the procedure to boot the Prisma unit. 1. Press the ON/OFF key. Please wait; the Prisma requires 35 seconds for a full cold-boot process. 2. At the end of the boot process the graphical user interface (GUI) appears. 3. Drawing: startup screen V1.1 7 4 Connecting probes and USB memory stick The following is the procedure to connect probes and a USB memory. 1. Connect the probe to the appropriate connector. 4. Drawing: UT connectors In order to connect phased array probes, unscrew and remove the grey protective cap that covers the I-PEX connector located on the right-hand side of the Prisma. The cap can be stored on the unit by screwing it on the back panel of the unit, over the CE mark. IMPORTANT When a phased array probe is not connected to the unit, the connector protective cap must be reinstalled in order to prevent water and dust ingress. If the phased array probe does not have an I-PEX connector, Sonatest can supply an appropriate adaptor. 5. Drawing: X4 phased array probe – DAAH phased array probe – X-clamp V1.1 8 Your Prisma will be equipped with either BNC or Lemo 1 connectors for conventional UT and TOFD probes. Sonatest can similarly supply appropriate cables and adaptors to suit probes with other types of connectors. You may use either, or both, channels A and B for conventional UT or TOFD. For pulse-echo scans, connect the probe to the Tx/Rx connector, labelled “T” on the case. For pitch-catch scans, connect the transmitter probe to the Tx/Rx “T” connector and the receiver probe to the Rx “R” connector. 2. Insert a USB memory stick into USB port 1. A miniature USB memory stick is supplied, which allows the cover to close while in use. 6. Drawing: PC type connectors Three USB connectors and an Ethernet connector are located on the side of the unit; protected by the waterproof cover. The USB ports can be used to connect external memory devices, a keyboard, a mouse, or a USB hub should you need to connect additional devices. The Ethernet port can be used for remote session support and to drive an external display via a VNC connection. If a USB memory device is connected to the Prisma then the user may opt to save configuration (.utcfg) and data (.utdata) files to it. Otherwise, by default and in the absence of an external memory device, these will be saved to the 5-GB internal memory. V1.1 9 5 Load an existing configuration The following is the procedure to load files. 1. Press the key to open the startup screen where you can select a user-defined or an example configuration file. 7. Drawing: startup screen 2. Use the Click Wheel to select Load Configuration and press . 8. Drawing: Using the click wheel V1.1 10 3. Press the button to toggle through the available memory location options. If you have connected a USB memory device, the list will include the following: a. The Internal partition is where you can save your own files. b. The Templates partition is where predefined example configuration files are stored. c. A USB device will provide external memory storage options. 4. Select Templates – Read Only. 9. Drawing: “Media Browser” (file open) 5. Press the key to toggle between the different views. 6. Press the key to select the Menu bar on the left of the screen. 7. Select the appropriate file in the list using the Click Wheel . 8. Press to open the selected file. File Extension Description .utcfg Contains the entire configuration for an inspection i.e. the probe, the wedge, the type of scan, the position of each cursor, the layout and the color palette to use. .utdata Contains the recorded data and everything a “.utcfg” file contains. .pdf Reports created by Prisma use the PDF file format. Imported PDF files can also be displayed by the Prisma. .png Screen captures created by Prisma use the PNG image standard. (PNG: portable network graphics) Table 1: List of supported file types. V1.1 11 6 Create a configuration The following is the procedure to create a new configuration with the help of the New Inspection Wisard. 1. To create a new configuration, press the key to open the startup screen. 2. Use the Click Wheel to select Start New Inspection Wizard and press . 10. Drawing: startup screen 3. Follow the instructions appearing on screen to set the parameters one by one. 11. Drawing: New Inspection Wizard (Step 1) 4. Select the required inspection type (conventional, TOFD, or phased array) and press on the keypad. V1.1 12 The number of steps required to complete a configuration depends on the option selected. A typical sequence of steps is as follows: 12. Drawing: New Inspection Wizard (step list) 5. After each step, press to progress to the next step. OR Press to return to the previous step. V1.1 13 7 Starting data acquisition The Prisma software simplifies your workflow by using three operational modes: • Configuration • Acquisition/Recording • Analysis These modes are controlled using the STOP , PLAY , and REC keys. The current operation mode is always displayed at the top-right corner of the screen by the and icons. 1. After opening a configuration file (.utcfg), the Prisma always starts in Configuration mode, also referred to as the STOP mode. Before starting the data acquisition it is good practice to review your setup. In Configuration mode the Prisma displays the following screen: 13. Drawing: UT Configuration mode (layout) 1. Menu 2. Configuration summary view 3. 3D view 4. Contextual help view V1.1 14 2. Press the key to select the Menu bar then use the Click Wheel to navigate. 3. uploads/S4/ prisma-guide.pdf
