Chapter 6 Integration
6.1 Integrator Functions
Active power integration and current integration can be carried out. All measurement values (and
computed values) can be displayed, even when integration is in progress, except for the
integrated values (watt hour or ampere hour) and elapsed integration time. Since integrated
values of negative polarity can be also displayed, the consumed watt hour (ampere hour) value
of the positive side and the watt hour value returning to the power supply of the negative side
(ampere hour: only when the measurement mode is DC), can be displayed seperately.
Integration Modes
The following three modes are available as integration modes.
Manual Integration Mode
• Integration starts: after having pressed the START key
• Integration stops:
• after having pressed the STOP key;
• when the integrated value reaches the maximum value 999999 MWh/MAh, or
when the integrated value drops to the minimum value –99999 MWh/MAh;
• when the elapsed integration time reaches the maximum of 10000 hours.
• Integration holds: the elapsed integration time and integrated values at the point
where integration stopped will be held until the RESET key is pressed.

Standard Integration Mode
• Integration starts: after having pressed the START key
• Integration stops:
• when the elapsed integration time is reached to preset time;
• when the integrated value reaches the maximum value 999999 MWh/MAh, or
when the integrated value drops to the minimum value –99999 MWh/MAh.
• Integration holds: the elapsed integration time and integrated values at the point
where integration stopped will be held until the RESET key is pressed.
