dmm.limit[Y].high.fail
where Y = 1 to 2 for limit
number
Attribute
Query for the high test results of limit Y.
Usage
To read the high fail indication of limit Y:
value = dmm.limit[Y].high.fail
Remarks
This attribute returns the results of high limit Y testing:
0 indicates test passed – measurement within the high limit
1 indicates test failed – measurement has exceeded high limit
A failed indication does indicate the high 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.
Example
To query the test results of high limit 2:
results = dmm.limit[2].high.fail
dmm.limit[Y].high.value
where Y = 1 or 2 for limit
number
Attribute
Indicates the high limit value for limit Y.
Usage
To read the high value of limit Y:
value = dmm.limit[Y].high.value
To write the high value of limit Y:
dmm.limit[Y].high.value = value
value: Valid range of -4294967295 to [phone]
Remarks
Use this attribute to specify or query the high 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_HIGH or dmm.trigger. EVENT_LIMIT2_HIGH).
Also see
dmm.limit[Y].high.fail (on page 13-142)
dmm.limit[Y].low.value (on page 13-144)
Example
To set high limit of limit 2 to 5:
dmm.limit[2].high.value = 5
dmm.limit[Y].low.fail
where Y = 1 or 2 for limit
number
Attribute
Query for the low test results of limit Y.
Usage
To read the low fail indication of limit Y:
value = dmm.limit[Y].low.fail
