Choose this function to read an RTD. Three wires must be use for both 2 and three wire RTDs.

1)Disconnect the RTD from the instrument being calibrated.

2)Press the T/C/RTD/Ω pushbutton until any RTD type (Pt, Ni or Cu) appears on the display.

3)Press the DISPLAY/SOURCE/READ push-button until SOURCE and any RTD TYPE appear on the display

4)Connect using 3 wires as in the diagrams on the opposite page. Use a 3 wire connection to read a 4 wire RTD (all four wires must be the same gauge). Spade lugs are recommend- ed to minimize any contact resistance.
