Applied Force sensor MA-522A / MA-521A |
Supports single-phase AC welders, DC inverter welders, AC inverter welders, and transistor type welders.
When you turn the encoder, you can scroll the screen, move the cursor, and select items. By pressing the encoder, you can the screen, select item that the cursor is located.
320x240 dots/4.7-inch -inch color LCD screen
Displays welding waveforms without using an oscilloscope.
This function can move a waveform and zoom in or out. Even if the waveform display goes off the screen, this function can redisplay the measured wave form. (Patent pending)
You can select the language from Japanese, English, Chinese, German, French, and Spanish.
- This function can record measured values and waveforms in internal flash memory and they can be analyzed and managed on a PC.
- Measurement data can be sent to a PC through RS-232C.
- Measurement data, waveforms, screen copies, etc. can be printed with the dedicated printer (sold separately).
- While the welding power is On, the pressurization and welding current can be measured at the same time. (This requires the MA-770A/MA-771A weld pressurization sensor, sold separately.)
- Since this has an external input function, voltage signals from other sensors (up to ±10 V) can be measured.
