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}
