dmm.inputdivider
Remarks
This attribute is only valid when dmm.func = "dcvolts". All other functions generate an
error and return nil when queried.
Changing functions with dmm.func (on page 13-137) will reflect the 10M ohm input
divider for that function.
The factory default and dmm.reset() (on page 13-161) function value is dmm.OFF.
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. 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 13-141). The auto clear setting
affects both the high and low limits of Y.

dmm.measure() (on page 13-150)
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 Y.
Usage
dmm.limit[Y].clear()
Remarks
This function clears the test results limit.
