NOTES This manual covers Keithley Models 2302, 2302-PJ, 2306, 2306-PJ, and 2306-VS
simulators (power supplies). Since the Model 2302 and 2302-PJ are single channel
battery simulators, functions related to the second channel (i.e., the charger channel)
are not available for the Model 2302 and 2302-PJ. Therefore:
battery and charger channel features contained in this manual apply for the
Models 2306, 2306-VS and 2306-PJ
only battery channel features contained in this manual apply for the Model 2302
and 2302-PJ
Refer to Appendix F for specific Model 2302 and 2302-PJ information.
Information contained in this section applies to all power supply channels (unless
otherwise noted). In this manual, channel 1 refers to the battery channel while
channel 2 refers to the charger channel (2306, 2306-VS and 2306-PJ feature only).
