NOTE

1 … 5 V output can be selected when ordering the device. The 1 .. 5

output is based on the 0 … 5 V output mode, but has been adjusted to

1 … 5 V by scaling the valid range to 1 … 5. In the scaled 1 … 5 V

output mode, 0 V is reserved for error output (AERR set to 0).

If the output includes the reminder 'remember to set jumpers', ignore the

reminder.
