KEW6310 Instrument Overview
.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.

Data transfer
Data in the CF card or internal memory can be transferred to a PC via USB connection or CF card
reader.
Transfer to PC via:
USB Card reader
CF card data (file) *
Internal memory data (file)
  *1  It is reccomended to transfer the data with big size by a use of CF card reader since trasfer of such data via
USB takes time. (transfer time : approx 4MB/ hour)
  *2 Data in the internal memory can be tranferred to a CF card.
 * As to the manipulation of the CF card, please refer to the instruction manual attached to the card.  * In order to save the data without any problem, make sure to delete the file other than the data
measured with this instrument in the CF card.
