ISO17657-compliant measurement
In addition to the arithmetic mean RMS which is a conventional calculation system, the RMS in a whole current flow time which is the ISO17657 (Resistance welding -- Welding current measurement for resistance welding -- )-compliant calculation system can be selected. For the ISO17657-compliant measurement, the dedicated ISO-compliant toroidal coil is required.
Supports multiple languages
Languages available are Japanese, English, Chinese, Korean, German, French, and Spanish.
■ New Features
Envelope function
Making the OK/NG judgment by comparing a waveform within an allowable range and a monitored waveform, enables management with waveforms in addition to conventional measured values.
(Up to 3 points 2 waveforms)

Envelope function

Measuring displacement Before-Welding
Measures Before-welding workpiece thickness, judge OK/NG of thickness.
■ Memory / Comumication / Printing
Memory
Measured values and waveforms can be saved in a built-in flash memory device/external USB.
Comunication
RS-232C, RS-485, Ethernet Simplex and duplex communication possible.(option)
Printing
Measured data and wavefome can be printing.
■ Judgment / Control function
  • By using a built-in force sensor / displacement sensor, it is possible to measure changes in pressurizing force / displacement amount even during production, display waveforms, judge OK/NG of welding.
  • Weld stop function shifted from 2 outputs to 3 outputs. Fine control of changes in displacement and applied pressure during welding.
  • With external input function, voltage input (± 10 V) current input (4 to 20 mA) from other sensors such as temperature sensor can be measured, waveform display, and OK/NG judge possible.
■ Long time measurement:MM-400B-02-05
  • Current and voltage are maesured in a maximum of 10 sec in AC/DC welding.
