Page 2 of the I/O Setup And Status screens is shown in Figure 20 and allows configuration and
display of the Analogue Inputs and Outputs.
The first Analogue Input is for the Weigh Scale and can be configured as either a 0-20mA or 4-
20mA signal.
Once the input type has been selected the input should be set to a known value and the Weigh
Scale Input should be checked. The Weigh Scale Input value displays 0 when at 0 or 4 mA
(depending on the Input Type setting) and displays 4095 when the input is at 20mA.
The second Analogue Input and Analogue Outputs are for future use.
