KEW6310 Instrument 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

Wiring configuration

 KEW6310 supports : Single-phase 2-wire, Single-phase 3-wire, Three-phase 3-wire, Three-phase 4-wire.

Measurement and calculation

  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.
