KEW6310Instrument Overview
1.Instrument Overview
Feature
This is a Clamp-type Power Quality Analyzer that can be used for various wiring systems. It can be
used for simple measurements of instantaneous/ integration/ demand values, and also for monitoring
waveforms and vectors, analyzing harmonics and measuring fluctuations in supply voltages and for
the simulation of power factor correction with capacitor banks. Data can be saved either in the internal
memory or a CF card, and can be transferred to a PC either via an USB lead or a CF Card reader.
Safety construction
Designed to meet the international safety standard IEC 61010-1 CAT.III 600V/ CAT.II 1000V
KEW6310 measures voltage (RMS), current (RMS), and calculates active/reactive/apparent power,
power factor, phase angle, frequency, neutral current and active/ reactive/ apparent electric energy.
(RMS)
Demand measurment
Electricity consumption can be easily monitored so as not to exceed the target maximum demand values.
Waveform / Vector display
Voltage and current can be displayed by waveform or vector.
Harmonic analysis
Harmonic components of voltage and current can be measured and analyzed.
Power quality analysis
Measuring Swell/ Dip/ Int, Transient, Inrush current, Unbalance ratio and flicker*, moreover, simulating
power factor correction with capacitor banks.
* Flicker measurement function is only available with ver.2.00 or later.
Saving data
KEW6310 is endowed with a logging function with a preset recording interval. Data can be saved by
manual operation or at pre-set time & date. Screen data can be saved by using Print Screen function.
Dual power supply system
KEW6310 operates either with an AC power supply or with batteries. Both dry-cell batteries (alkaline)
and rechargeable batteries (Ni-MH) can be used. Battery charge while rechargeable batteries installed in
the instrument is possible. In the event of interruption, while operating with AC power supply, power to
the instrument is automatically restored by the batteries in the instrument.
Large display
Color display with large screen
Light & compact design
Clamp sensor type, compact and light weight design
Application
Data in the internal memory or CF card can be saved in a PC via a USB lead or a CF Card reader. As
well supplied software facilitates setting, optional analysis software facilitates data analysis.
Input/output function
Analogue signals from thermometers or light sensors can be measured simultaneously with electrical
power data via 2 analogue inputs (DC voltage); signals exceeding a preset threshold values at each
range can be transmitted to alarms devices via 1 digital output.

Getting Started KEW6310
3. Getting Started
The KEW6310 operates with either an AC power supply or batteries. In the event of AC power
interruption, power to the instrument is automatically restored by the batteries in the instrument. Drycell batteries (alkaline) and rechargeable ones (Ni-MH); can be both used. It is also possible to charge
rechargeable batteries in the instrument.
Remove the Selector Switch Cover, and slide the Selector Switch to left or right depending on the
batteries to be used.
