Furthermore, various functions of Equivalent calibration, Sequential control, Set value restoration and Recovery from power failure are available.
F701+ is an ideal weighing indicator which considering performance and convenience.
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 .
Set value restoration
Set value can be restored, in case set value is changed by mistake.
"Load cell" is a sensor that measures a weight or a force.
For the load cells as well as amplifiers and indicators where the load cells are connected to, there are "4-wire type" and "6-wire type". If not wired properly, it may cause not only inaccurate measurements, but also may be affected by the temperature or the cable length.
This time, we will explain the wiring method of both 4-wire type and 6-wire type.

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
