dmm.inputdivider
Example
To enable the input divider for DC volts:
dmm.func = “dcvolts”
dmm.inputdivider = dmm.ON
dmm.limit[Y].autoclear
where Y = 1 or 2 for limit
number
Attribute
Indicates if limit Y should be cleared automatically or not.
Usage
To read the auto clear setting:
value = dmm.limit[Y].autoclear
To write the auto clear setting:
dmm.limit[Y].autoclear = value
Use one of the following:
dmm.ON or 1 to enable auto clear
dmm.OFF or 0 to disable auto clear
Remarks
When this attribute is set to dmm.ON,a limit fail condition will track how the
measurements are taken. If the measurement failed limit, then the fail indication will
be set. If the next measurement passes limit, the failed limit condition clears.
Therefore, if scanning or taking a series of measurements with auto cleared enabled
for a limit, then the last measurement limit dictates the fail indication for the limit. To
know if any of a series of measurements failed the limit, then set the auto clear setting
to off. Otherwise, when set to dmm.OFF, a failed indication will not be cleared
automatically and will remain set until it is cleared by
dmm.limit[Y].clear
(on page 9-
94). The auto clear setting affects both the high and low limits of Y.

dmm.measure
(on page 9-102)
Example
Enable auto clear on limit 2:
dmm.limit[2].autoclear = dmm.ON
dmm.limit[Y].clear
where Y = 1 or 2 for limit
number
Function
Clears the test results of limit.
Usage
dmm.limit[Y].clear()
Remarks
This function clears the test results limit.
Also see
dmm.limit[Y].high.fail
(on page 9-95)
dmm.limit[Y].low.fail
(on page 9-96)
Example
To clear the test results for both the high and low limit 2:
dmm.limit[2].clear()
