Calibration Setups
Refer to Test Equipment for the equipment required for calibration. Refer to the
Measurement Setups section for information about setting up the voltmeter, connecting
the current shunt, and connecting the electronic load.
For optimum performance, all verification and calibration procedures should comply with the following
recommendations:
l Ambient temperature is stable, at 23°C ±5°C.
l Ambient relative humidity is less than 70%.
l 30 minute warm-up period before verification or adjustment.
l Cables as short as possible, twisted or shielded to reduce noise and inductance.
l Load lead lengths for Models N678xA SMU must be between 1 and 4 feet. This is also recom-
mended for other power modules.
Front Panel Connections
Except for Cal Setup C, do not connect anything to the Sense terminals. Check the front panel 4 wire
LED to see whether 4 wire sensing is enabled (LED is lit) or disabled (LED not lit). To change the 4 wire
sense settings, press [Settings], then navigate to and select Advanced. Under Sense, select Local or 4
Wire sensing. Connect all leads to the output terminals as shown in the following figure.
The following figures show the calibration test set-ups. Connect all leads to the output terminals as
shown in the figure.
