The KL3222 is designed for 4-wire measurement
The KL3222 is designed for 4-wire measurement. +R/-R are the current-carrying connection cables,
+RL/-RL are the currentless sense cables.
If a sensor is to be connected using 2/3 wire connection technology and the KL3202 cannot be
used, the following applies
• one or two jumper(s) per channel must be set externally, see wiring diagram
• the setting "four-wire" must be retained in R32, the 2/3-wire measurement is not calibrated by the
manufacturer
• the falsifying lead resistance should be entered in R38. The firmware subtracts this lead resis-
tance from the measured resistance in order to determine a corrected temperature. This calcula-
tion of R38 is active in all 3 modes 2/3/4-wire of R32.
