The below setting screen appears.
Math Setup
Displaying/recording in case of computation error
Used to determine whether +OVER or -OVER be displayed/saved in case of computation
error.
Time axis scale for TLOG SUM
For TLOG.SUM of time series, data is added at each measurement interval. However,
in the case of an input having unit of /s, /min or /h like flow rate, the computation result
will differ from the actual value, if addition of data is carried out. In this case, setting
TLOG TIME SCALE according to the unit of the input will cause the data measured at
measurement intervals to be processed according to the unit of the input.
For instance, if the measurement interval is 2s and input value is 100 m3/min, the
computation result will be 30000 after the elapse of one minute, since 100 is added
every 2 seconds. Setting TLOG TIME SCALE to /min will cause the measured data to be
multiplied by 2s/60s at each measurement interval, thus making the result close to the
actual input value.
If this function is set to OFF, simple addition of data will be carried out.
Process of abnormal data during TLOG or CLOG (TLOG CH ERROR)
Used to select the process method for abnormal data obtained during TLOG or CLOG.
• ERROR : Abnormal data processed as a computation error.
• SKIP : Abnormal data ignored and computation is continued.
