Series 2400 SourceMeter® Quick Start Guide Section 1: Introduction
Use the following menu sequence to select the auto ohms or manual ohms measurement method:
Press CONFIG > press MEAS
Ω
> select SOURCE > select AUTO or MANUAL
Ohms source readback
With source readback enabled, the SourceMeter measures both V and I and uses these values for
the ohms calculation. This feature provides optimum accuracy for front panel operation since the
measured source value is more accurate than the programmed source value. For remote
operation, the user specifies the functions to measure.
Use the following menu sequence to enable or disable source readback:
Press CONFIG > press MEAS
Ω
> select SRC RDBK > select ENABLE or DISABLE
Ohms measurement procedures
The auto ohms and manual ohms measurement procedures are provided in Tables 4 and 5. They
assume that the DUT is already connected to the SourceMeter. (See
Basic connections .) Note that
resistance accuracy specifications are based on 4-wire sensing.

cator off.
Notes
1. If sourcing I, you will be selecting the V measure range. If sourcing V, you will be selecting the I
measure range.
2. The compliance range determines the maximum measurement range that can be selected.
