High sampling rate & resolution

High-Speed A/D conversion and powerful digital processing capability of 2400 times/sec.. High display resolution of 1/100000 (max).

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

Application software for USB interface

With communication through USB interface, logging, graph, display, setting parameters, and calibration can be done.

Compact size

it can be fit into a limited space!
Lightvweing & compact body for 35mm DIN rail mount.

Equivalent input calibration

Theoretical calibration can be performed easily by registering the capacity and rated output of load cells.

Digital peak & Bottom hold. Upper and lower limit comparison

OK / NOK judgement in fast process can be made.

Input conversion value display

The output signal level of load cell can be displayed in mV/V for monitor purpose.

6 digit display

24 bit A/D convertor enables 6 digit display.
