The hand-held MM-380 has been designed to provide quick, precise and comprehensive measurements of the welding process. The MM-380 utilizes a weld through sensor measures current, voltage and force simultaneously between the electrodes. The 5” color display provides precise graphical displays of waveform time and amplitude, in addition to numeric peak and average values. Measurement setup, waveform analysis and menu navigation is very straightforward, and achieved using a rotary encoder. Waveforms and data can be output through an optional in printer or via COM port for screen capture and data collection.
