Section 2: General operation
Step 5: Observe readings on the display.
Press the TRIG key if necessary to trigger the instrument to begin taking readings. The readings are
on the top line, and source and limit values are on the bottom line.
Step 6: Turn the output off
When finished, turn the output off by pressing the OUTPUT ON/OFF control. The OUTPUT indicator
light switches off.
Remote source-measure commands
Basic source-measurement procedures can also be performed through a remote interface. To do this,
send the appropriate commands. The following table summarizes basic source-measure commands.

* smuX: For Models 2601B, 2611B, and 2635B, this value is smua (SMU Channel A); for Models 2602B, 2604B, 2612B, 2614B,
2634B, and 2636B, this value can be smua (for SMU Channel A) or smub (for SMU Channel B).
