Set Idle Time This command congures how long the unit can
0x5C be left out of analysis before setting an Instrument
fault. Idle time allows you to exit the Monitoring
mode without causing an Instrument fault (if the
idle time is > 0). You simply set the idle time to an
appropriate idle (non-monitoring) time. If the idle
time has expired and the unit is not in the
Monitoring mode, an instrument fault will be
issued. An idle time setting of 0 disables this
option.
