Gallery Hioki portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The new and improved PQ is a power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. New features include the ability to drive current sensors straight from the PQA and enhanced recording capabilities. Select from Value Kits for added savings.

Firmware for the Model PW The current newest firmware versions are shown below. A version update is highly recommended if you are running older firmware. If the version number on your model PW is Ver 1. Version Upgrade History V1. Instead of the maximum or minimum value of an inter-harmonic current content percentage acquired as TIMEPLOT data, an instantaneous value was erroneously outputted.
Other minor bugs fixed. Newly employed GPS module support. Countermeasures against GPS rollover. When deleting all the currently displayed screen copy files saved as BMP files , the cursor became inoperative. Enhancements 1. Addition of the loading measurement data function V1. When events continuously occur, there will be no gaps in the saved interval data. Fixed bugs 1. There should not be a unit sign.
POWER QUALITY ANALYZER
Note: An optional current sensor is necessary to measure current or power parameters. Select from Value Kits for added savings. When they do, for example due to an equipment failure or abrupt surge in demand, engineers face the need to analyze the cause quickly. Analyze equipment power problems Capture the full range of power supply anomalies, including momentary interruptions, voltage drops, and frequency fluctuations, while recording trends to help investigate the causes of unexpected equipment malfunctions and sudden stoppages. Record quality data for power systems Record fluctuations in voltage, current, power, harmonics, and flicker when connecting a highly variable system such as a renewable energy source or EV charging station to the grid.
