If Power Failure Occurs While Report Function Is Active
The DR recorder takes different actions depending on the length of a power failure.
If the power failure time is longer than 12 hours:
The DR recorder makes a report immediately after it recovers from the power failure and then
stops making reports. It does not execute printing based on the settings for automatic printing.
Print out reports either using the communication function or from the FUNC menu.
Results of computing: The DR recorder computes data measured up to the point immediately
before the power failure.
Time of report making: The time when the power failure occurred.
If the power failure is less than 12 hours:
The DR recorder takes different actions depending on the time it recovers from the power
failure.

Handling of Faulty Data
If data being computed contain any faulty data, the DR recorder treats the data as summarized in
the following table, depending on the type of computing and faulty data.
