Data Format Description
The measurement range is pre-defined, based on your selection of the module
data format. The corresponding range limited defined in the following tables:

2-/3-Wire RTD
This option is used only for RTD and Resistance measurements. You may
specify using a 2-wire or a 3-wire measurement. When running 3-wire
measurements, you may also enable lead wire resistance compensation:
Index 2-/3-Wire RTD
0 3-wire with compensation
1 2-wire
When using 3-wire measurement with lead wire resistance compensation, the
lead wire resistance value is measured every 60 seconds using a dynamic channel
timer to verify. If the lead wire is detected as open circuit/broken wire, the
secondary measurement and the timer functionality is reset. Once the open circuit
condition is resolved, the secondary measurement is retriggered immediately
instead of waiting for the next period.

Description
Default. The module scales analog input
data to the actual current/voltage values
in mA or mV for the selected input range.
The module scales analog input data to
the actual current/voltage values in mA *
10 or mV * 10 for the selected input
range.
The value presented to the controller is
proportional to the selected input and
scaled to the maximum data range
allowed by the bit resolution of the ADC.
The value presented to the controller is a
percentage of the user range.
