Voltage And Current; Limits - Tektronix KEITHLEY SourceMeter 2600B Series User Manual

Section 4: Operation

Voltage and current

The following table lists the source and measure limits for the voltage and current functions. The full
range of operation is explained in "Operating boundaries" in the Series 2600B Reference Manual.

Limits

When sourcing voltage, you can set the instrument to limit current or power. Conversely, when
sourcing current, you can set the instrument to limit voltage or power. In steady-state conditions, the
instrument output does not exceed the limit. The maximum limit is the same as the maximum values
listed in the following table.
The limit circuit limits in either polarity regardless of the polarity of the source or limit value. The
accuracy of the limit opposite in polarity from the source is diminished unless the instrument is in
operation (on page 4-5). The maximum limits are based on source range.
