code may be queried by reading the cFM2Device.Last-
Fault property. The fault code may be dismissed by
calling the cFM2Device.DismissFault() method.
A Probe Removed event indicates that a probe was
removed from the meter. Data transmission will cease
when the probe is removed. If the meter USB disconnect
event occurs when the probe is connected, a Probe
Removed event will not happen before the Meter
Removed event.
A Probe Added event indicates that a probe was added
to the meter. Data transmission can happen only after a
probe is attached.
A Power On event indicates that meter power has been
turned on.
A Power Off event indicates that meter power has been
turned off.
A Measurement Data event indicates a valid measure-
ment reading is available The measurement reading is in
two parts: a value (Watts or Joules) and a period. The
value may be queried by reading the cFM2Device.Last-
Data property. The period may be queried by reading the
cFM2Device.LastPeriod property. The period is
expressed in units of 8 µsec intervals when a pyroelectric
probe is attached. When a thermopile or optical probe is
attached and an overtemperature condition exists, the
period is 1; otherwise, it is 0.
