What settings are affected by quick setup?
For accurate measurements, settings such as range and sync source must be properly config-
ured. Executing quick setup automatically configures the following settings to the Hioki-recom-
mended values for the selected wiring mode (phase system): voltage and current ranges, sync
source, lower measurement frequency limit, integration mode, harmonic sync source and rectifi-
cation system.
Execute quick setup when using the instrument the first time, and when changing to a different
line configuration.
