The Resistance Spot Weld Analyzer consists of several parts (Figure 1). The base unit consists of a Windows-based tablet PC with installed software. The probe has a 52-element matrix transducer which connects to an internal DSP board located within the RSWA. Two removable batteries provide up to 9–12 hours of run time when disconnected from a power source. A charger/AC adapter provides power for simultaneous device operation and battery charging. The device is designed with a ruggedized case to provide protection against shock and mechanical damage.
