Measure only (voltage or current)
The figures below show the configurations for using the instrument exclusively as a voltmeter or
ammeter.
As shown in the following figure, to configure the instrument to measure voltage only, set it to source
0 A and measure voltage.
Figure 5: 2600B measure voltage only
Set the voltage limit to a level that is higher than the measured voltage. If the voltage limit is
set to a level that is lower than the measured voltage, excessive current flows into the
instrument. This current could damage the instrument. Also, when connecting an external
energy source to the instrument when it is configured as a current source, set the output off
state to the high-impedance mode. See Output-off states (on page 2-40) for more information
on the output-off states. See “Limits” in the Series 2600B User's Manual for details on
compliance limits.
In the following figure, the instrument uses a 2-wire local sensing configuration and is set to measure
current only by setting it to source 0 V and measure current. Note that to obtain positive (+) readings,
conventional current must flow from HI to LO.
