Basic Source-Measure Operation
Basic circuit configuration
The fundamental source-measure configuration for the SourceMeter (with Remote PreAmp)
is shown in Figure 3-1, where the Source is either the V-Source or the I-Source. If not using the
Remote PreAmp, Input/Output HI and LO is accessed at the rear panel of the mainframe.

When using the Remote PreAmp, nothing should be connected to INPUT/OUTPUT
HI banana jack on the mainframe. If using mainframe INPUT/OUTUT HI, the cable
to the Remote PreAmp should be disconnected.
Operation considerations
The following paragraphs discuss warm-up period, auto zero, V-source protection, and
source delay.
Warm-up
The SourceMeter must be turned on and allowed to warm up for at least one hour to achieve
rated accuracies. See Appendix A for specifications.
Auto zero
Every A/D conversion (reading) is calculated from a series of zero, reference, and signal
measurements. With auto zero enabled, all three of these measurements are performed for each
reading to achieve rated accuracy. With auto-zero disabled, zero and reference are not mea-
sured. This increases measurement speed, but zero drift will eventually corrupt accuracy. With
auto zero disabled, periodically change measurement speed.
