Configure Analog Input Point

To enable a Analog input point:

• Select it by Clicking the box to check it.

• Next set the Configuration for 12-Bit Single-Ended Analog Input or 12-

Bit Differential Analog Input.

• Set the Units to Volts or another label.

• Set how many Units is equal to 0 Volts.

• Set how many Units equals a change of 1 Volt.

In the case of units with the standard +5 Volt reference and no external

divider, a change of 1 volt =1 volt. If we use an external voltage divider to

divide the voltage by one half, and our input voltage is 10 volts full scale, a

change of 1 volt =2 volts. Enter 2 in the box. If we divide by 10, a change of

1 volt =10 volts. Using our standard +5 volt reference, a change in units will

always be 1 or more.

During Sampling or Logging, only active points are sampled.
