7.1.1 Analog input

Analog sensors output a continuous voltage or current signal that varies with the phenomena
measured. Sensors compatible with the VOLT 100 series output a voltage. Current output can be
made compatible with a resistive shunt.
Sensor connection is to H/L terminals configurable for differential (DIFF), single-ended (SE), or
period-average inputs. For example, differential channel 1 is comprised of terminals 1H and 1L,
with 1H as high and 1L as low.
Maximum input voltage range: ±5000 mV

Measurement resolution range: 0.020 to 14.756 µV

7.1.1.1 Single-ended measurements

A single-ended measurement measures the difference in voltage between the terminal
configured for single-ended input and the reference ground. Single-ended terminals are labeled
