Procedure
TheEVkitisfullyassembledandtested.Followthesteps
below to verify board operation:
1) Verify the two jumper wires (included) are properly
secured in the terminal block in accordance with the
2-wireRTDSensorConnectordiagramonthePCB’s
silkscreen(Figure6).
2) Verify the 1kΩ resistor is properly secured in the
terminal block connecting the RTDIN+ terminal to the
RTDIN- terminal.
3) Set the EV kit hardware on a nonconductive surface
that ensures that nothing on the PCB gets shorted to
the workspace.
4) PriortostartingtheGUI,connecttheEVkithardware
to a PC using the supplied mini-USB cable, or equiva-

administrator privileges may be required to install the
USB device.
6) Once the device driver installation is complete,
visit www.maximintegrated.com/MAX31865evkit to
download the latest version of the EV kit software,
MAX31865EVKitSoftwareInstall.ZIP.Savethe EVkit
software to a temporary folder.
7) Openthe.ZIPfileanddoubleclickthe.EXEfiletorun
