Dmm.drycircuit - Keithley 3700A Series Reference Manual

Series 3700A System Switch/Multimeter Reference Manual

dmm.drycircuit

This attribute enables or disables the dry circuit feature of the 4-wire resistance measure function.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
state = dmm.drycircuit
dmm.drycircuit = state
state
Details
The dry circuit setting only applies when dmm.func is set to "fourwireohms" or
"commonsideohms".
Enabling dry circuit limits the open-circuit voltage to below 20 mV, which is often required with
low-glitch measurements, such as measuring switch and relay contact resistance.
When dry circuit is enabled, offset compensation is automatically enabled.
An error is generated if:
•
You try to set dmm.drycircuit for a function other than "fourwireohms" or
"commonsideohms". Error 1114, "Setting conflicts with function selected" is generated.
•
You query dmm.drycircuit for a function other than "fourwireohms" or
"commonsideohms". nil is returned, along with error 1114.
•
The state is invalid.
The dry circuit setting is saved with the dmm.func function setting, so if you use another function,
then return to the previous function, the dry circuit setting you set previously is retained.
Example
dmm.func = "fourwireohms"
dmm.drycircuit = dmm.ON
