Wiring the measurement circuit
Connecting the current input terminal to the load
You can connect the current input terminal to the L side or the N side.
This section will present the wiring that is used to measure comparatively small currents,
such as measuring the standby power of LCD TVs. This wiring method is designed to
minimize the effect of the current flowing through the input resistance of the voltage input
terminal.
