OPERATION
System Calibration

To confirm proper operation, select channel 7 and look for a voltage in the general vicinity of zero. The offset portion of the system calibration removes errors caused by the input signal conditioning circuitry, as well as offset errors in the A/D converter itself. Confirm that the reading is close to zero volts. Channel 6 should read close to +5 volts after a system calibration. The full-scale calibration removes gain and signal conditioning errors.
