4.2.4 Analog output
The analog unit sends a 4–20 mA signal that is proportional to the number of particles that are counted in a given sampling time. A data acquisition system installed by the user and connected to an output channel of the analog unit receives the signal. The 4–20 mA output current is scaled for a range between zero and a maximum count set by the user. Analog units cannot be networked. Refer to section 3.6.9 on page 25 and section 3.6.10 on page 26 for setting the Analog output scaling and testing the Analog output.
