Portable Diagnostic Unit

A compact power and communication device designed to quickly test and verify ShapeArray installations prior to configuration for automated data collection.

Measurand designed the Portable Diagnostic Unit (PDU) so clients have a portable, cost-effective way to verify SAAV’s patented cyclical installation, ensuring your ShapeArray delivers the highest quality deformation data possible.

Interface units like the PDU control communications and power between the ShapeArray and the computer. The PDU contains a high-quality DC to DC converter that boosts and regulates the voltage supplied by the 10.80 V Lithium-Ion battery to a constant 13.5V. The PDU also provides a voltage boost to 16.5V to allow for longer communication cables. A fast-charging battery allows for a full charge in 105 minutes. The PDUs USB-C connectivity allows for communication and power through a single input.

The PDU is field-ready with the following accessories included inside a lightweight, water-resistant carrying case: a USB-C Power Delivery Charger, USB-C Power Delivery Car Charger, a USB-C cord, and a USB-C to USB 2.0 Type-A Adapter.
