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 time of integration.
Since integrated values of negative polarity can be also displayed, the consumed watt hour
(ampere hour: only when the measurement mode is DC) 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 of 999999 MWh/MAh, or when the
integrated value of negative polarity reaches –99999 MWh/MAh;
• when the elapsed time of integration reaches the maximum of 10000 hours 00
minutes 00 seconds.
• Integration holds: the elapsed time of integration 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 time of integration reaches the integration timer preset time;
• when the integrated value reaches the maximum of 999999 MWh/MAh, or when the
integrated value of negative polarity reaches –99999 MWh/MAh.
• Integration holds: the elapsed time of integration and integrated values at the point
where integration stopped will be held until the RESET key is pressed.
