F701+ product movie

High sampling rate & resolution

High-Speed A/D conversion and powerful digital processing capability of 500 times/sec.

High resolution of 1/10000 in all input range.

* It can be changed to 100times/sec.

Measurement can be performed quickly and precisely due to high speed A/D conversion.

Auto filter adjustment

Capable of adjusting filter automatically according to an operating condition. Helpful for setting at the test operation.

Equivalent calibration

Equivalent calibration can be made easily by just inputting rated capacity and output of loadcell to F701+ with key button.

Recovery form temporary stop / power failure

Temporary measurement stop, and Operation restart mode are available. Measurement can be performed continuously from the middle .

Various functions are available

  • Digital low pass filter As it is resistant to vibration, measurement can be performed quickly and precisely. *Conventional analog filter is also selectable
  • Sink type / source type are available Type of I/O signal are selectable form Sink and Source.
  • Displaying accumulated value with one-touch Accumulated value can be shown with one-touch
  • Connecting with printer by using RS-232C communication Time data can be output for efficient data management.
  • Various optional interface D/A converter, BCD output, RS-232C, RS485(Selectable from Modbus-RTU and UNI format), PROFIBUS-DP are available.
  • I/O board can be easily replaced on site
