Machine-mounted Model MM-370 and handheld Model MM380 include 5 in. color graphical display that indicates waveform time and amplitude, in addition to numeric peak and average values. Capable of setting limits and configuring machine I/O, MM370 measures current, voltage, force, and displacement. Using weld-through sensor, MM380 measures current, voltage, and force simultaneously between electrodes. Waveforms and data can be output through printer or via COM port.
