Configure these settings for each pulse channel receiving input from a pulse
output device such as a watt-hour or flow meter.
Use the scaling function to display integrated pulse counts as the correspond-
ing physical units (such as Wh or VA) of the measurement parameter (p. 58).
Integration (Count) Measurement Settings
• When using the scaling function, the integrated pulse count can
be displayed after conversion to the measurement target’s prop-
erty (Wh, VA, etc.). (p. 58)
• The count will be saturated when the pulse count exceeds
1,073,741,823. If there is a possibility that this number may be
exceeded, it is recommended to set the integration mode to
instantaneous and tabulate the results later with Excel or a simi-
lar application.
