dmm.adjustment.date
Example
Also see usage for setting date.
NOTE
For following assume set date to July 4, 2007.
To query date and format the response as mm/dd/yyyy:
print(os.date("%m/%d/%Y",
dmm.adjustment.date))
07/04/2007
To query date and format the response as mm/dd/yy:
print(os.date("%x",
dmm.adjustment.date))
07/04/07
dmm.aperture
Attribute
Indicates the aperture setting for the active DMM function in seconds.
Usage
To read the aperture:
value = dmm.aperture
value
: Represents the present aperture setting in seconds
To write the aperture:
dmm.aperture = value
value
: Represents the desired aperture:
For 50Hz, the range is 10e-6 to 0.250 second.
For 60Hz, the range is 8.33e-6 to 0.250 second.
For frequency and period, 0.01 to 0.273 second.
Remarks
This is the aperture setting for the DMM and it applies to the selected function as
indicated by
dmm.func
(on page 9-91). Querying the aperture when the selected
function does not have an aperture associated with it will cause nil to be returned.
An error is generated if a command is received when
dmm.func
(on page 9-91) =
―continuity‖ or ―nofunction‖.
Changing functions with
dmm.func
(on page 9-91) has no effect on this setting.
If the detector bandwidth (
dmm.detectorbandwidth
(on page 9-85)) setting is 30 or less
for ―acvolts‖ or ―accurrent‖, then an error message will be generated when trying to set
the aperture for these functions. The detector bandwidth setting is one of three values
(based on input parameter): 3, 30, or 300.
