dmm.drycircuit
Attribute
Indicates the dry circuit setting for the selected DMM function.
Usage
To read the dry circuit:
value = dmm.drycircuit
value
: Represents the present dry circuit setting
To write the dry circuit:
dmm.drycircuit = value
value
Represents the desired dry circuit setting. Use one of the following:
dmm.ON or 1 to enable dry circuit.
dmm.OFF or 0 to disable drycircuit
Remarks
This is the dry circuit setting for the DMM and it applies to the selected function as
indicated by dmm.func. Querying the setting when the selected function does not
support it will cause nil to be returned.
This command only applies when dmm.func = ―fourwireohms‖ or ―commonsideohms‖.
All other function settings will generate an error if the command is received. Also, an
error will be generated if the value is invalid.
Changing functions with dmm.func has no effect on this setting.
The factory default and dmm.reset function value is dmm.OFF.
Example
To enable dry circuit for four-wire ohms:
dmm.func = "fourwireohms"
dmm.drycircuit = dmm.ON
dmm.filter.count
Attribute
Indicates the filter count setting for the selected DMM function.
Usage
To read the filter count:
value = dmm.filter.count
value
: Represents the present filter count setting
To write the filter count:
dmm.filter.count = value
value
: Represents the desired filter count setting from 1 to 100
Remarks
This is the filter count setting for the DMM and it applies to the selected function as
indicated by dmm.func. Querying the setting when the selected function does not
support it will cause nil to be returned.
This attribute indicates the number of measured readings to yield one filtered
measurements when filtered measurements are enabled.
The command
will generate an error when dmm.func = ―frequency‖, ―period‖,
―continuity‖ or ―nofunction‖. Also, an error will be generated if the value is out of range.
Changing functions with dmm.func has no effect on this setting.
The
dmm.reset
(on page 9-112) function sets the filter count to 10.
