2. BASIC SETTING AND OPERATION
2.1 BASIC SETTING
This section describes flow and procedure of the basic setting.
The following shows the flow and procedure to set the input to 0 – 20 mA AC and the display to 0.00 – 600.00 A AC with
the input code ‘2’ as an example.
2.1.1 BASIC SETTING FLOW
The basic setting is as shown in the following flowchart.
2.1.2 RELATION AMONG INPUT TYPE, INPUT SCALING AND DISPLAY SCALING
The relation among input type, input scaling and display scaling is as shown in the following figure and chart.
Input type: Type of input signal to 47DAC (measuring range)
Input scaling: 0% input value (input scaling value Zero) and 100% input value (input scaling value Span)
Display scaling: 0% display value (display scaling value Zero) and 100% display value (display scaling value Span)
