The CR1000 measures the following sensor analog output types:
• Voltage
o Single-ended
o Differential
• Current (using a resistive shunt)
• Resistance
• Full-bridge
• Half-bridge
Sensor connection is to H/L] terminals configurable for differential (DIFF) or
single-ended (SE) inputs. For example, differential channel 1 is comprised of
terminals 1H and 1L, with 1H as high and 1L as low.

Measurement Sequence
An analog-voltage measurement, as illustrated in the figure Simplified Voltage
Measurement Sequence
(p. 306), proceeds as follows:
1. Switch
2. Settle
3. Amplify
4. Integrate
5. A to D (successive approximation)
6. Measurement scaled with multiplier and offset
7. Scaled value placed in memory
