NOTES: 1. This represents a protection circuit that is very
high impedance until the voltage across it exceeds
approximately 3V. Above 3V, the protection turns
on and allows current to flow through it.

.
Measure only (V or I)
shows the configurations for using the SourceMeter exclusively as a
voltmeter or ammeter. As shown in
, 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
measured 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 “
” earlier in this section for details.
, the SourceMeter is configured to measure current-only by setting
it to source 0V and measure current. Note that in order to obtain positive (+)
readings, conventional current must flow from IN/OUT HI to LO.
