is an integer specifying the threshold at which the Quality Factor Warning Output will
turn on. If the QF goes below this value for longer than the Quality Factor Warning
Timeout, the output will turn on. To turn back off again, the QF must go above the
threshold for longer than the timeout.
Voltage High: QF is less than the Warning Threshold
Voltage Low: QF is greater than or equal to the Warning Threshold
This output is available on either pulse output, or on the Index Pulse output, as an alter-
nate configuration. See the

is an integer specifying the number of milliseconds that the QF must be below the
Quality Factor Warning Threshold before the warning output will trigger.
The default value is 10,000, which is 10 seconds. This means that the QF must be below
the threshold for 10 seconds before the output will trigger. This setting should be kept
fairly large to avoid nuisance alarms.
