Section 16: Calibration Series 2600 System SourceMeter® Instruments Reference Manual
Calibration procedure
Step 1. Prepare the Series 2600 for calibration
a. Connect the Series 2600 to the controller IEEE-488 interface or RS-232 port using a
shielded interface cable.
b. Turn on the Series 2600 and the test equipment, and allow them to warm up for at least
two hours before performing calibration.
c. Make sure the IEEE-488 or RS-232 interface parameters are set up properly (press
MENU > RS232 to configure the interface).
Step 2. Voltage Calibration
a. Connect the Series 2600 to the digital multimeter using the 4-wire connections shown in
Figure 16-1, and select the multimeter DC volts function.
b. Send the following commands in order to initialize voltage calibration:
smua.cal.unlock("KI0026XX")
smua.reset()
smua.source.func = smua.OUTPUT_DCVOLTS
smuX.source.calibratei(range,
cp1expected, cp1reference,
cp2expected, cp2reference)
smuX.source.calibratev(range,
cp1expected, cp1reference,
cp2expected, cp2reference)
smuX.contact.calibratelo
(cp1measured, cp1reference,
cp2measured, cp2reference)
smuX.contact.calibratehi
(cp1measured, cp1reference,
cp2measured, cp2reference)
Calibrate current source range:
2
±range (range to calibrate).
cp1expected (source value programmed for cal. point 1).
cp1reference (reference measurement for cal. point 1).
cp2expected (source value programmed for cal. point 2).
cp2reference (reference measurement for cal. point 2).
Calibrate voltage source range:
2
±range (range to calibrate).
cp1expected (source value programmed for cal. point 1).
cp1reference (reference measurement for cal. point 1).
cp2expected (source value programmed for cal. point 2).
cp2reference (reference measurement for cal. point 2).
Calibrate the low/sense low contact check measurement.
cp1measured (value measured by SMU for cal. point 1).
cp1reference (reference measurement for cal. point 1).
cp2measured (value measured by SMU for cal. point 2).
cp2reference (reference measurement for cal. point 2).
Calibrate the high/sense high contact check measurement.
cp1measured (value measured by SMU for cal. point 1).
cp1reference (reference measurement for cal. point 1).
cp2measured (value measured by SMU for cal. point 2).
cp2reference (reference measurement for cal. point 2).

Description
1. smuX = smua for the Model 2601/2611/2635; smuX = smua (Channel A) or smub (Channel B) for the Model 2602/2612/2636.
2. If you have version 1.1.4 firmware, or earlier, then your passwords are KI002601 for the Model 2601, and KI002602 for the
Model 2602.
3. Calibration point 1 should be performed at approximately 0% of range; calibration point 2 should be performed at approximately
90% of range. See
Table 16-2 or Table 16-3 for calibration points.
