An Overrange packet event indicates that the current
reading is overranged.
An Overtemperature event indicates that the probe is in
an overtemperature condition. If the probe is in an over-
temperature condition, one Overtemperature event will
accompany every measurement data event.
A Measurement Data Lost event indicates that the
meter communication system has dropped data and is not
processing data fast enough. Data synchronization is lost
and the system automatically attempts to resynchronize
the data stream. A 1-2 second interruption in the data
stream will occur during resynchronization attempts.
Error Callback There is a variety of reasons for the root cause of errors.
When the DLL server detects an error, the
IFM2DeviceEvents_DisplayErrorToClient () callback
method is called. The callback method may find the
string description of the error in the IFM2DeviceEvents_
CallbackMessage property.
Zero Status
Callback
Probe zeroing monopolizes the meter and can last up to
60 seconds. Zero status events are dispatched to the
application code using the IFM2DeviceEvents_
DisplayZeroDeviceProgressToClient() callback method.
Zero status events are dispatched—once per second
while zeroing is in progress—to permit the application
code to monitor progress. The cFM2Notify callback
object CallbackMessage and ZeroDeviceTimeout-
Counter properties are used to monitor zero progress.
The CallbackMessage string is a text description of the
callback event. The ZeroDeviceTimeoutCounter integer
