Clicking Read from WI-I/O-EX will read the scales out of the unit (if any) and display

them in the scales grid. Note that the dip switches should be set correctly for this result to

be relevant.

Choose the desired scale for each channel in the Scale box. Click the Save scales to WI-

I/O-EX button, and check that the scales are updated in the WI-I/O-EX Detected panel.

4.4.2 Current input

Current inputs may be selected in the scales 0 to 10mA, 0 to 20mA, or 4 to 20mA. For

each scale, the minimum to maximum signal levels are represented by 4000 hex to C000

hex. Table 4-2 shows how the WI-I/O-EX-12 current readings translate to outputs in

other wireless products.
