Note
Waiting Time
specifies the maximum period of time, for how long the system/software will
wait for the previous peak (for example N
2
in a dual N-C measurement), to reach background
again, and delay the subsequent peak jump.
For example:
if you enter a waiting time of 10 seconds, the software will delay the peak jump as
specified in the time event list by a maximum of 10 seconds.
• If the N
2
peak has already reached background until the time specified in the time events list,
then the peak jump will occur straight away at that specified time.
• If the N
2
peak hasn't reached background until the specified time in the time events list and the
entry for waiting time is for example 10 seconds (you can also enter a different waiting time or
0 seconds here), the peak jump will be delayed by a maximum of that number of seconds, so
that the N
2
peak still has that number of seconds to reach background.
• If the N
2
peak reaches background within these seconds of waiting time, the peak jump will
then occur. If the N
2
peak does not reach background within the waiting time, the peak jump
will definitely occur after the waiting time period.
