Configure these settings for each pulse channel receiving input from a pulse output
device such as a watt-hour or flow meter. Make these settings on the [CH] screen.

• Use the scaling function to display integrated pulse counts as the cor-
responding physical units (such as Wh or VA) of the measurement
p
arameter (p. 69).
• The counter saturates at 1,073,741,823 counts. If you expect to
exceed this count, we recommend measuring with the Integration
Mode (Count Mo) set to Instantaneous (Inst), and summing later with
a spreadsheet program.
