6.2 Setting Integration Mode, Integration Type, and Integration Timer
Selecting the Integration Mode
The following selections are available. The initial value is nor.
• nor: Select this for manual or standard integration mode. Depending on the
integration timer, this instrument will automatically decide the appropriate mode.
• Cont: Select this for the continuous integration mode.
Selecting the Integration Type
The following selections are available. The initial value is St.
• St: Standard type. Integrates the active power or current that is obtained using the
normal measurement method, which obtains the active power or current from the
sampled data over the period that is synchronized to the input signal. Select the
standard type for steady-state input signals that have a constant period such as a
sinusoid.
• Ad: Advanced type. Integrates the active power or current obtained over a fixed
period of sampled data, irrespective of the period of the input signal. Select the
advanced type for intermittent signals with a frequency of 50 or 60 Hz.
Note
Select integration type Ad when integrating the power of devices that are controlled through
intermittent signals or devices on which the amplitude of the voltage or current changes
drastically. If the load fluctuation is large, the value obtained on this instrument may differ
from that obtained on other instruments using a different integration method.
Selecting the Integration Timer
Specify how many hours, minutes, and seconds to perform the integration. The
selectable range is from 0.00.00 (0 hours 0 minutes 0 seconds) to 10000.00.00
(10000 hours, 0 minutes, 0 seconds). The initial value is 0.00.00.
• 0.00.00: When nor is selected in the integration mode menu, integration is
performed in the manual integration mode. If Cont is selected, an error code is
displayed and the integration is not performed.
• 0.00.01 to 10000.00.00: The time during which integration is to be performed when
using the standard or continuous integration mode. The standard or continuous
integration mode is specified in the integration mode menu.
