6: Measuring 4-wire resistance with offset compensation DMM6500 6½ Digit Multimeter
6-2 DMM6500-900-01Rev. A / April 2018
Device connections
This example application uses the DMM6500 to perform a 4-wire resistance-device measurement
using offset compensation. Both the front and rear-panel connections are safety banana jacks. You
can use either the front or the rear input terminals.
You must use either the front or the rear terminals. You cannot mix the front and rear connections.
Make sure that the front-panel TERMINALS switch is set to the terminals you are using. The light for
FRONT or REAR is illuminated indicating which terminals are being used.
To use the 4-wire connection method:
1. Connect one set of test leads to the INPUT HI and INPUT LO terminals.
2. Connect the other set of test leads to the SENSE HI and SENSE LO terminals.
