- Page 16 ADwin Inputs and Outputs Please pay attention to a low internal resistance of the power supply unit (of the input signals), because it may have influence on the measuring accuracy. If this is not possible: – Depending on the output resistance a linear error is caused. You can compensate this by multiplying the measurement value with a corresponding factor and get a sort of recalibration.

For the voltage range of −10V … +10V applies: = −10V The ADwin-Gold has a programmable gain (PGA), with which you can amplify Gain factor k the input voltage by the factors 1, 2, 4, and 8.

ADwin Inputs and Outputs Tolerance Ranges Slight variations regarding the calculated values may be within the tolerance range of the individual component. Two kinds of variations are possible (in LSB), which are indicated in this hardware manual: – The integral non-linearity (INL) defines the maximum deviation from the ideal straight line over the whole input voltage range. - Page 19 ADwin Inputs and Outputs Contrary to the standard instructions ADC(), ADC12() and DAC() the instruc- tions for direct access do not have any test routines. Before you use them we recommend to learn more about time sequences, program structures and func- tions sequences in an ADC.
