Appendix 1 Periodic Printout and Printout Using the TLOG Timer (/M1 Option)
This section explains the operation of the periodic printout report (statistical calculation)
and the TLOG computation for special cases. In the explanation below, statistical
calculation represents computation in periodic printout report mode or TLOG
computation.
Operation during Power Failures
If a power failure occurs in the middle of statistical calculation, the operation is as follows
when the power recovers.
The statistical calculation resumes when the power recovers. The exact operation will
vary depending on whether the power is restored before or after the printout time.

Procedure of Handling "Over" Values during Periodic Printout
*
When an "over" value is input for sum or average computation, that value is not used in
the computation.
* An "over" value on a measurement channel refers to +Over or –Over. See section 12.4.
An "over" value on a computation channel refers to a value that is less than or equal to
–100000000 or greater than or equal to 100000000 excluding the decimal.
Statistical Calculation Operation
Statistical calculation data is printed immediately after power
is restored. The measured/computed data up to the time of
the power failure is used. At the next printout time, data after
the power recovery is used to create and print the statistical
calculation data.
restored. It is printed on the first printout time after recovery.
The data used is measured/computed data from before
and up to the power failure, and from the time of recovery
up to the printout time. The "report start date/time" in this
case is the periodic printout date/time closest to and prior to
the power failure. The "report end date/time" is the current
periodic printout date/time.
The data is printed at the printout time after the power
recovers. The measured/computed data excluding the
power failure period is used.
