For dc volts, ac volts, or frequency, the configuration is now complete for this
channel. The instrument returns to Inactive Mode.
4. For resistance measurements, one more step is required to specify 2-terminal (2T) or
4-terminal (4T) measurements. Since 4-terminal measurements require two
channels, 4-terminal measurements can be set up on channels 1-10 only. For each 4-
terminal channel, a corresponding channel (11-20) ten numbers higher is reserved
for the additional two connections required. Press the buttons as follows:
Choose between two terminals (2T) and four terminals (4T).

specify 2-terminal (2T) or 4-terminal (4T) measurements and the R0 value.
Since 4T measurements require two channels, 4-terminal measurements can be set
up on channels 1-10 only. For each 4T channel, a corresponding channel (11-20) ten
numbers higher is reserved for the additional two connections required.
Choose between two terminals (2T) and four terminals (4T).
