3. Use the precision input source to provide a 15 mA input across a
channel's input terminals.
4. Verify that the input data is between 15110 and 15260 counts.
5. Repeat steps 3 and 4 for each remaining channel.
To verify:
1. Configure your module for ±10 V input on all 4 channels using the
following configuration word values:
Address
O:e.0
O:e.1
O:e.2
O:e.3
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.
4. Verify that the input data is between 31805 and 32131 counts.
5. Repeat steps 3 and 4 for each remaining channel.
If the input data is out of range, call the Spectrum Controls Technical Services to
make arrangements for returning your module for factory calibration.
