dmm.linesync

This attribute determines if line synchronization is used during the measurement.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
state = dmm.linesync
dmm.linesync = state
state
Details
This attribute is only valid when dmm.func is set to "commonsideohms", "continuity",
"dccurrent", "dcvolts", "fourwireohms", "temperature", or "twowireohms". All other
functions generate an error when written and return nil when queried.
When line synchronization is enabled, measurements are initiated at the first positive-going zero
crossing of the power line cycle after the trigger.
The line sync setting is saved with the dmm.func function setting, so if you use another function, then
return to a previous function, the line sync you set previously is retained.
Example
dmm.func = "fourwireohms"
dmm.linesync = dmm.ON
