dmm.limit[Y].low.fail
where Y = 1 or 2 for limit
number
Remarks
This attribute returns the results of low limit Y testing:
0 indicates test passed – measurement within the low limit
1 indicates test failed – measurement has exceeded low limit
A failed indication does indicate the low limit caused the failure. You may read the
measurement event register of the status model to see fail indication as well. This
response only has meaning if the limit's auto clear setting is disabled and the limit is
enabled. Otherwise, it will indicate the results of the last limit test when enabled.
Also see
digio.trigger[N].stimulus (on page 13-91)
Example
To query the test results of low limit 2:
results = dmm.limit[2].low.fail
dmm.limit[Y].low.value
where Y = 1 or 2 for limit
number
Attribute
Indicates the low limit value for limit Y.
Usage
To read the low value of limit Y:
value = dmm.limit[Y].low.value
To write the low value of limit Y:
dmm.limit[Y].low.value = value
value: Valid range is -4294967295 to [phone]
Remarks
Use this attribute to specify or query the low limit value of limit Y. When limit Y testing
is enabled (dmm.limit[Y].enable (on page 13-142)), the measurement value must be
greater than this value to avoid causing a fail indication for the limit. The default value
is -1 for limit 1 and -2 for limit 2. You may set or get the value regardless if the limit is
set to a digio trigger stimulus (digio.trigger[N].stimulus =
dmm.trigger.EVENT_LIMIT1_LOW or dmm.trigger. EVENT_LIMIT2_LOW).

dmm.limit[Y].low.fail (on page 13-143)
dmm.limit[Y].high.value (on page 13-142)
Example
To set low limit of limit 2 to -5:
dmm.limit[2].low.value = -5
dmm.linesync
Attribute
Attribute indicating whether line sync is used during the measurement.
