Power/Signal Lost Recovery Actions
If the power is cut or the input signal is lost while a pro-
file is running, the instrument will use the defined Pro-
file Recovery Method once the signal / power returns.
The profile recovery method is set in the profile header.
The possible profile recovery options are explained be-
low.
Note:
Recorder versions always use option E (Con-
tinue profile) if the “off time” is less than the Profile
Recovery Time setting. If the “off time” is longer,
the defined Profile Recovery Method is used.
Note:
With option E, after the power returns profile
bar graph resets and shows the remaining/elapsed
time for the profile only since re-starting.
