Scaling for Current Output Voltage Operation For Voltage Operation in the default unipolar mode (0 to +10 volts), user data is scaled so that 0 volts corresponds to a count of 0 and +10 volts corresponds to a count of 32000. In this mode, you can enter up to 32767 for an overrange of approximately 10.24 volts output. In the –10 to +10 volt range user data is scaled so that –10 volts corresponds to a count of –32000 and +10 volts corresponds to a count of +32000. In this range, you can enter –32768 to +32767 for an overrange of approximately –10.24 volts to +10.24 volts. Scaling of the voltage output for both the 0 to +10 volt range and the –10 to +10 volt range is as shown below. %AQ (decimal) VOLTAGE (V) 0 a44658 10 10 32000 32000 0 Bipolar Mode %AQ (decimal) VOLTAGE (V) a45718 0 10 32000 Unipolar Mode 0 Figure 12-4.
