2. Channels specifying calculation
For channels specifying calculation, data after processing the specified calculation is recorded or displayed.
3. Calculating max/min/avg value
1) Calculation
reset
Calculation is reset automatically at specified intervals. Therefore the maximum, minimum and average
values are calculated in each interval.
2) Start time of calculation
This is valid for the first calculation after setting only. Calculation is not performed and waited until start time.
The calculated data during this waiting period is invalid.
4. Integration
Integration operation can be processed on measured value of each channel and the result can be
displayed/recorded.
For a channel No. selecting integration, an alarm value is set for calculated (integrated) value.
The data (calculation result) of a calculation set channel
is obtained using the following formula.

1) Resetting
integration
(1) Reset by remote contact
When using remote contacts (optional), a start and reset of integration can be executed with a remote
contact signal. When a calculation is started by a remote contact reset, integration value will be reset
at set intervals.
(See “13-1. External Operation Settings”.)
(2) Reset after specified interval
After integration operation is started, the integration value is reset automatically after a specified
interval and then the operation is restarted.
2) Max integration value
The maximum integration value is 99999 (it actually depends on the decimal point position of result: 99.999
to 99999). If integration value exceeds the maximum value, it will be reset to 0 and the integration operation
continues.
