To verify:
1. Configure your module for ±10 V input on all 4 channels using the
following configuration word values:
Address Binary Value Decimal Equivalent
O:e.0 0000 0000 0010 0001 33
O:e.1 0000 0000 0010 0001 33
O:e.2 0000 0000 0010 0001 33
O:e.3 0000 0000 0010 0001 33
e = slot number
2. Let the operating temperature stabilize for 2 minutes.
3. Use the precision input source to provide a 10 VDC input across a
channel’s input terminals.
