3. Identify the analog channel types (voltage/current) that physically exist on the acquisition
board. Select the channel types based on the jumper/tap settings of analog channels
and group similar channel types. Once the grouping is done, click Calibrate System.
Consider the following example:
The acquisition unit has 3 current and 3 voltage channels in the following manner:
•
Channels 1, 4, and 7 are current channels with tap settings 10 A and
•
Channels 2, 3, and 5 are voltage channels with tap settings 140 V
In this situation, perform the following during calibration:
•
For channels 1, 4, and 7, select Type as Current 10 AC and Group as 1. This
indicates that Group 1 corresponds to a set of channels of type Current 10 AC.
•
For channels 2, 3, and 5, select Type as Voltage 140 AC and Group as 2. This
indicates that Group 2 corresponds to a set of channels of type Voltage 140 AC.
