Measure only (V or I)

Figure 6-16 shows the configurations for using the SourceMeter exclusively as a

voltmeter or ammeter. As shown in Figure 6-16A, the SourceMeter is configured

to measure voltage only by setting it to source 0A and measure voltage.

CAUTION V-Compliance must be set to a level that is higher than the mea-

sured voltage. Otherwise, excessive current will flow into the

SourceMeter. This current could damage the SourceMeter. Also,

when connecting an external voltage to the I-Source, set the output-

off state to the high-impedance mode. (See

Section 13, “Output-off

states.”)

In Figure 6-16B, the SourceMeter is configured to measure current-only by setting

it to source 0V and measure current. Note that in order to obtain positive (+) read-

ings, conventional current must flow from IN/OUT HI to LO.
