Temperature Measurement (RTD)
Function: RTD Sensor Measurement
Also check the Sensor setting. Make sure you select the same
sensor type than what is connected to MC4. Otherwise your
measurement results are unreliable. For information on creating
custom Platinum Resistance Temperature (PRT) type RTD sensors,
see Part C, chapter Custom PRT Sensors on page 106.
The picture below displays the active terminals.
The two leftmost terminals are
used in 2-wire systems. MC4
automatically checks the
connection and displays the found
wiring system (2-wire, 3-wire or 4-
wire) in the upper right corner of
the measuring window.

For more information concerning wiring options, see Resistance
and RTD Measurement, Connections on page 118.
By default the additional info row at the bottom of the window
displays the measured RTD resistance. More of additional info row
on page 90.
Note.
If the measured resistance value is infinite or very high
(> 4000 ohm), the text "+OVER" is displayed in the measuring
window. This means that the circuit is broken or the connection is
wrong. Wrong connection may also cause erroneous reading,
typically too low. If necessary, use the 2-wire ohm measurement to
check the wiring before final connection.
