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. It will
indicate the results of the measurement if autoclear is enabled.
digio.trigger[N].triggersource
To query the test results of low limit 2:
results = dmm.limit[2].low.fail
Indicates the low limit value for limit Y.
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 +4294967295
Use this attribute to specify or query the low limit value of limit Y. When limit Y testing
is enabled (digio.trigger[N].triggersource = dmm.trigger.EVENT_LIMIT1_LOW or
dmm.trigger. EVENT_LIMIT2_LOW ), 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
triggersource.
dmm.limit[Y].low.fail (on page 9-96)
dmm.limit[Y].high.value (on page 9-95)
To set low limit of limit 2 to -5:
dmm.limit[2].low.value = -5
Attribute indicating whether line sync is used during the measurement.
To read the linesync state:
value = dmm.linesync
To write the linesync state:
dmm.linesync = value
value: Set to one of the following:

set to dmm.ON or 1 to enable line sync

dmm.OFF or 0 to disable line sync
