Programming / configuration
Scaling of measured values
Each channel can be configured individually for a defined measuring range, e.g.
For measuring
•
with wire strain gauges 2 mV/V,
•
with wire strain gauges 10 mV/V,
•
with active sensors 0-5 V,
•
with temperature sensors PT1000,
•
with type K thermocouples,
•
with active sensors 0–10 V,
The measuring range is set using the command “set_gain”.
105% of the input signal matches a value range of 0x0000 to 0xFFFF.
Measuring range 2.0 mV/V
Measuring range ±2 mV/V (set_gain 0xB2 <p1> <p2>) with p1=ch, p2=0x01

Conversion of digital output value to analogue input signal:
Output value = Highbyte * 256 + Lowbyte;
Input signal Ud = (output value - 32768) / 32768 * 2.10 mV/V;
Measuring range 10.0 mV/V
Measuring range ±10 mV/V (set_gain 0xB2 <p1> <p2>) with p1=ch, p2=0x02
