5.4.3 Tool Analog Inputs

The tool analog inputs are non-differential and can be set to either voltage and current
on the I/O tab, see part II. The electrical specifications are shown below.
Two examples of how to use analog inputs are shown in the following subsections.
5.4.3.1 Using the Tool Analog Inputs, Non-differential
The example below shows how to connect an analog sensor with a non-differential
output. The output of the sensor can be either current or voltage, as long as the input
mode of that analog input is set to the same on the I/O tab. Remember to check
that a sensor with voltage output can drive the internal resistance of the tool, or the
measurement might be invalid.
5.4.3.2 Using the Tool Analog Inputs, Differential
The example below shows how to connect an analog sensor with a differential output.
Connect the negative output part to GND (0V) and it works in the same way as a
non-differential sensor.

CAUTION:
1. Analog inputs are not protected against over voltage in current
mode. Overrating the limit in the electrical specification can
cause permanent damage to the input.
