Appendix B: Calibration

B-11
Use the procedures in this section to calibrate the 2606B.
These procedures require accurate test equipment to measure precise DC voltages and currents.
The 2606B contains two independent SMU modules. Each module requires separate adjustment.
The instructions in this section use the web interface (refer to
(on page 2-18)).
You can also use remote programming commands. Refer to
(on page 5-1) for
information on using commands to control the instrument.
Product specifications are subject to change. Listed uncertainties and test limits are provided only as
an example. Always verify values against actual product specifications.
Environmental conditions
Temperature and relative humidity
Conduct the calibration procedures at an ambient temperature of 18 °C to 28 °C, with relative
humidity of less than 70 percent (unless otherwise noted).
Product specifications that are listed as 18 ºC to 28 ºC assume adjustment has been done at 23 ºC.
If the 2606B is adjusted at a different temperature, the specifications apply to ±5 ºC of that
adjustment temperature.
Line power
The 2606B requires a line voltage of 100 V to 240 V at a line frequency of 50 Hz or 60 Hz. The
instrument must be calibrated within this range.
Warmup period
Allow the 2606B to warm up for at least two hours before performing calibration.
If the instrument has been subjected to temperature extremes (those outside the ranges stated
above), allow additional time for the instrument's internal temperature to stabilize. Typically, allow one
extra hour to stabilize an instrument that is 10 °C outside the specified temperature range.
Also, allow the test equipment to warm up for the minimum time specified by the manufacturer.
Adjustment considerations
When performing the adjustment procedures:
•
Make sure that the test equipment is properly warmed up and connected to the correct 2606B
terminals.
•
Always allow the source signal to settle before calibrating each point.
•
Do not connect test equipment to the 2606B SMU through a scanner or other switching
equipment.
•
If an error occurs during calibration, the 2606B will generate an appropriate error message.
