Programming / configuration
For programming Windows DLL and Labview Vis can be downloaded from the website.
Optionally it is possible to programm the measuring amplifier directly via serial interface or
USB with ASCII Codes.
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
