Analog Range Key
The Series 2000 control unit allows you to direct process readings to either
of the two analog output ports on the bottom front of the control unit.
See the “Select An Analog Output Port” section for help on how to select
an analog output port. All functions in this section are directed to a spe-
cific analog output port.
The Analog Range key (Figure 4-4) section of this chapter provides help
on how to do the following:

Define what information should be sent to the analog output port
during a calibration. Decide whether to hold the output at the last
process reading taken before the start of calibration or track the cali-
bration readings (Set Track/Hold).

Define analog output range as 0 to 20 mA or 4 to 20 mA (Set Current
Mode).

Define what type of information the analog output should track
(Select Function). Choices are O
2
readings, cell temperature, cell mil-
livolts, and thermocouple millivolts.
