4.14 - BitsToVolts

Converts a 12-bit (0-4095) binary value into a LabJack voltage. No hardware communication is involved.

Volts=((2*Bits*Vmax/4096)-Vmax)/Gain where Vmax=10 for SE, 20 for Diff.

Declaration:

long BitsToVolts (    long chnum,
                      long chgain,
                      long bits,
                      float *volts )

Parameter Description:
Returns: LabJack errorcodes or 0 for no error.
Inputs:

  • chnum – Channel index. 0-7=SE, 8-11=Diff.
  • chgain – Gain index. 0=1, 1=2, …, 7=20.
  • bits – Binary value from 0-4095.

Outputs:

  • *volts – Voltage.
