Processing Against Absence of Measurement

Measurement may not take place if the DA is loaded beyond its processing capability. If absence of

measurement occurs, the DA compensates for the missing data with the data it measures

immediately after recovering from the absence of measurement (the data for the period with no

measurement thus match those acquired immediately after recovering from the absence of

measurement).

If Power Failure Occurs While Report Function Is Active

The DA takes different actions depending on the length of a power failure.

If the power failure time is longer than 12 hours:

The DA 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 DA 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 DA takes different actions depending on the time it recovers from the power failure.

of power failure except the power failure time

Handling of Faulty Data

If data being computed contain any faulty data, the DA treats the data as summarized in the

following table, depending on the type of computing and faulty data.

Type of Faulty Data Average Minimum/ Instantaneous ValueSum

Maximum

Positive overflow Excluded from Included in Takes faulty data as Excluded from

computing computing the result of computing computing

Negative overflow Excluded from Included in Takes faulty data as Excluded from

computing computing the result of computing computing

Channels included in Excluded from Excluded from Takes faulty data as Excluded from

measurement set to SKIP computing computing the result of computing computing
