The Resistance Spot Weld Analyzer consists of several parts (Figure 1). The base unit consists of a Windows-based tablet PC with an attached DSP board and installed software. The probe has a 52-element matrix transducer which connects to the DSP board. An external battery provides up to 6 hours of run time when disconnected from a power source. A charger/AC adapter provides power for simultaneous device operation and battery charging. A soft case holds all these components together and provides protection against shock and mechanical damage.
