Integrator Functions

Integration Modes
IM 253401-01E
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 integration elapsed 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.
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 of 999999MWh/MAh, or when the
integrated value of negative polarity reaches –99999MWh/MAh;
• when the integration elapsed time reaches the maximum of 999 hours and 59 minutes.
• Integration holds: the integration elapsed time and integrated values at the point where
integration stopped will be held until the RESET key is pressed.
