Ohms Measurements

•

Ohms configuration menu

 — Outlines the ohms configuration menu that allows 

you to set up various ohms measurement aspects.

•

Ohms measurement methods

 

— Discusses auto and manual ohms measurement 

methods and how to select them.

•

Ohms sensing

 

—

 

Covers 2-wire and 4-wire ohms sensing.

•

Offset-compensated ohms

 

—

 

Describes offset-compensated ohms, which can be 

used to overcome the effects of offsets when making low-resistance measurements.

•

Ohms source readback

 — Covers enabling and disabling ohms source readback.

•

6-wire ohms measurements

 — Describes the basic procedure for setting up the 

SourceMeter for 6-wire ohms measurement, which can be used for measuring 
resistor networks and hybrid circuits.

•

Remote ohms programming

 — Summarizes the basic remote commands required 

to program the SourceMeter for ohms measurements and gives several typical pro-
gramming examples.
