Overview
1.1 Product Overview
This instrument is a power analyzer that can analyze the power conversion efficiency by
simultaneously measuring the input and output powers of an object under measurement. The
instrument can include up to eight input modules and support various lines to be measured
according to your applications by combining wiring configurations from single-phase to three-phase
four-wire configurations as desired.
1.2 Features
Up to eight modules can be included
By combining two types of input modules with one to eight channels as desired, the measurement system
most suitable for your applications can be configured in a single instrument.
Combination of the two types of input modules enables the configuration of the most
suitable system
Two types of input modules are available: a general-purpose input module with high withstand voltage, the
U7001, and an input module with world-class accuracy of
±
0.03% and world-class high resolution and high-
speed sampling, the U7005.
According to the performance you need, the two types of input modules can be combined and installed on the
PW8001.

Automatically recognizes current sensors
(p. 42)
The instrument automatically acquires information on
current sensors connected to itself and corrects their
phase errors.
This significantly reduces the setting time before
measurement and strongly supports accurate power
measurement.

Simple Settings (Quick Set)(p. 45)
The Quick Set function allows measurement conditions to be set to typical values at once according to the
selected lines to be measured.
