Features

Minimized zero and span drifts because of its microcontroller technology and
high accurate, very low temperature drift 24 bits ADC and 16 bits DAC
converters.

Long time stability and low temperature drifts eliminates the frequent
readjustment period.

Digital adaptive anti-vibration filters to minimize environmental vibrations.

Very easy and user friendly digital adjustment via rotary switches located on
the front of the instrument.

All instruments are adjusted to 0
– 10 V and to 4 – 20 mA analog output
ranges for 0
– 10 mV load cell signal range in production as default. (only for
2mV/V load cells)

Calibration at PLC does not require readjustment after changing instrument
because of matching in the production.
