Model 2606B System SourceMeter® Instrument Reference Manual
Use 4-wire remote sensing for the following source-measure conditions:
•
Sourcing or measuring voltage in low impedance (<1 kΩ) test circuits.
•
Enforcing voltage compliance limit directly at the DUT.
When using 4-wire local sensing connections, make sure to properly configure the 2606B
mode selection
Contact check connections
The contact check function prevents measurement errors due to excessive resistance in the source or
sense leads. See
Contact check requires both source and sense connections. Refer to
connections
Guarding and shielding
You can optimize source-measure performance and safety with the effective use of guarding and
shielding (noise and safety shields).
