Additional Input Type comments:
Acts as a digital input.
Sets the maximum frequency and equivalent flow rate in the engineering range 0
to 6000 Hz. (A frequency of 0.01 to 6 KHz can be used to create an analog value.)
This parameter counts pulses and is recommended only for use with electromagnetic
flowmeters.
Sets the required electrical range.
Note. Applicable only to Millivolts, Milliamps, Volts and Ohms.

Sets the required electrical range.
Note. Applicable only to Millivolts, Milliamps, Volts and Freq. Input.
Selects the linearizer type required to condition the input signal.
Notes. For thermocouple applications using an external fixed cold junction, set
Input Type to Millivolts and select the appropriate linearizer type.
Not applicable for Pulse Input, Digital volt-free, 24V Digital parameters.
The selected units are used by the linearizer and displayed in the Operator pages.
Not applicable for: Pulse Input, Digital volt-free, 24V Digital parameters.
Thermocouple and RTD inputs are restricted to deg C, deg F, Kelvin –
see Appendix C, page 108 for analog input (engineering) units.
Engineering decimal places – selects the resolution required to be displayed
for the input value.
