OPERATION
2 - 25
Start/stop datalogging manually
If manual datalogging mode has been selected from the
normal operation menu, toggle through the menu using the
[MODE] key until the “
Start Datalog?”
prompt is
displayed. Pressing the [Y/+] key turns on datalogging.
Likewise, pressing the
[Y/+]
key while “ Stop Datalog?”
is being displayed, turns off datalogging.
The other three datalogging options will start and stop
automatically without any user intervention:
Datalogging event
Each time a datalogging operation is initiated, a datalog
event is created. Information, such as start time,
datalogging period, alarm limits, etc. will be recorded in
the event header, followed by the measurement data. If
more than 900 measurement intervals are recorded in one
event, a new event will be created automatically.
Datalogging pause
Under the following conditions, the datalogging will be
paused automatically:
1) When entering programming mode, datalogging will
stop. Upon exiting the programming mode, the
datalogging will resume.
2) When entering PC Communication standby mode,
datalogging will stop. Upon exiting the PC communication
standby mode, datalogging will resume
only if
datalogging mode was set to automatic mode.
In either case, a new datalog event will be created when the
datalogging is resumed.
