Voltage Limited Measurements
Voltage limited resistance measurements clamp the open circuit voltage
to predefined limits.
• Voltage limits apply only to 4-wire ohms measurements.
• Voltage limited resistance measurements are only available on
the 10 Ω and 100 Ω ranges. If a manual range is selected in either
2-wire or 4-wire ohms, and then Voltage Limited measurements are
enabled, the range will be set to the highest valid range (either 10 Ω
or 100 Ω ).
• The open circuit voltage can be limited to 20 mV, 100 mV, or 500 mV.
• Setting the Low Power measurement mode will cancel the
Voltage Limited mode.
• Front panel operation: Enable or disable the voltage limit under the
5: LOW VOLT Ω command in the MEASure menu.
Set the voltage limit under the 6: LoV LIMIT Ω command in the
MEASure menu.
• Remote operation: the following command enables or disable the
low voltage limit mode:
SENSe:FRESistance:VOLTage:LIMit {OFF|ON}
Set the limit with the following command:
SENSe:FRESistance:VOLTage:LIMit:VALue {<
value >|MIN|MAX}
