Features
•
Minimized zero and span drifts because of its microcontroller technology
•
24-bits ADC and 16-bits DAC converters.
•
Long time stability and low temperature drifts eliminates the frequent
readjustment period.
•
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 analogue 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.
