dmm.autodelay
Example
To enable auto delay for DC volts:
dmm.func = "dcvolts"
dmm.autodelay = dmm.ON
To set auto delay to set once:
dmm.autodelay = dmm.AUTODELAY_ONCE
dmm.autorange
Attribute
Indicates the auto range setting for the DMM.
Usage
To read the auto range:
value = dmm.autorange
value:
Represents the present auto range setting (1 = ON, 0 = OFF).
To write the auto range:
dmm.autorange = value
value
: Represents the desired auto range setting. Use one of the following:
dmm.ON or 1: Enables auto ranging.
dmm.OFF or 0: Disables auto ranging.
Remarks
This is the auto range setting for the DMM. It applies to the selected function as
indicated by
dmm.func
(on page 9-91). Querying the auto range when the selected
function does not have an auto range associated with it will cause nil to be returned.
An error is generated if command is received when dmm.func = ―temperature‖,
―frequency‖, ―period‖, ―continuity‖ or ―nofunction‖. Also, an error will be generated if the
value is out of range.
Changing functions with
dmm.func
(on page 9-91) has no effect on this setting.
The default setting is dmm.ON.
Example
To enable auto ranging for two-wire ohms:
dmm.func = "twowireohms"
dmm.autorange = dmm.ON
