DANGER

WARNING

CAUTION

Measurement Category

To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various
electrical environments, categorized as O to CAT.IV, and called measurement categories. Higher-numbered
categories correspond to electrical environments with greater momentary energy, so a measuring instrument
designed for CAT.III environments can endure greater momentary energy than one designed for CAT.II.

O : Circuits which are not directly connected to the mains power supply.
CAT.II : Electrical circuits of equipment connected to an AC electrical outlet by a power cord.
CAT.III : Primary electrical circuits of the equipment connected directly to the distribution panel,
and feeders from the distribution panel to outlets.
CAT.IV : The circuit from the service drop to the service entrance, and to the power meter and

KEW6315 Safety warnings

 Never disconnect sensors from the connectors of the instrument while the instrument is in use.
 Connect to the downstream side of a circuit breaker since a current capacity at the upstream side

is large.
 Do not touch two lines under test with the metal tips of the test leads.

Caution

 Caution should be taken since conductors under test may be hot.
 Never apply currents or voltages exceeding the maximum allowable input for the instrument for a

long time.
 Do not apply currents or voltages for the Clamp sensors or Voltage test leads while the instrument

is off.
 Don’t use the instrument at dusty places or to be spattered.
 Don’t use the instrument under a strong electric storm or in the vicinity of energized object.
 Never give strong vibrations or drop shocks.
 Insert an SD card to the slot with the top side turned up. If the card is inserted up-side-down, the SD

card or the instrument may be damaged. Confirm the

 While using an SD card, do not replace or remove the card. (The symbol blinks while accessing

SD card.) Otherwise, the saved data in the card may be lost or the instrument may be damaged.

- Clamp sensor -

 Do not bend or pull the cable of the Clamp sensor.

- Treatment after use -

 Power off the instrument and disconnect the Power cord, Voltage test leads and Clamp sensors from

the instrument.
 Remove the batteries if the instrument is to be stored and will not be in use for a long period.
 Remove the SD card when carrying the instrument.
 Never give strong vibrations or drop shocks when carrying the instrument.
 Do not expose the instrument to direct sunlight, high temperatures, humidity or dew.
 Use a damp cloth with neutral detergent or water for cleaning the instrument. Do not use abrasives

or solvents.
 Do not store the instrument if it is wet.

1.2 Features KEW6315

1.2 Features

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 analysis of harmonics

and events related to power quality and for the simulation of power factor correction with capacitor banks.

Moreover, it can display waveforms and vectors of voltage and current. Data can be saved either on the

SD card or in the internal memory, and can be transferred to PC via USB, or in real time via Bluetooth®

communication.

Safety construction

Designed to meet the international safety standard IEC 61010-1 CAT.IV 300V/ CAT.III 600V/ CAT.II 1000V.

Power quality analysis

KEW6315 is designed to meet the international standard IEC61000-4-30 Class S and can measure
frequency and r.m.s. voltage with high accuracy, and also can analyze harmonics. Moreover, it can measure
swell, dip, interruption, transient, inrush current and flicker, gapless, all at once.

Power measurement

KEW6315 measures active/reactive/apparent power, electrical energy, power factor, r.m.s. current, phase
angle and neutral current simultaneously.

Wiring configuration

KEW6315 supports: Single-phase 2-wire (4-system), Single-phase 3-wire (2-system), Three-phase 3-wire

(2-system) and Three-phase 4-wire.

Demand measurement

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.

Saving data

KEW6315 is endowed with a logging function with the preset recording interval. Data can be saved by manual
operation or by specifying date & time. Screen data can be saved by using the Print Screen function.

Dual power supply system

KEW6315 operates either with AC power supply or with batteries. Size AA alkaline dry-cell batteries and
size AA Ni-MH rechargeable batteries can both be used. To charge size AA Ni-MH rechargeable batteries,
use the charger which is manufactured by the same company as the batteries. In the event of power
interruption, while operating with AC power supply, power to the instrument is automatically restored by the
batteries in the instrument.

Large display

TFT color display with large screen.

Light & compact design

Clamp sensor type, compact and light weight design.

Application

Data in the SD card or the internal memory can be saved in PC via USB. Analysis of the downloaded
data and instrument settings are possible by using the special software “KEW Windows for KEW6315”.
Real-time communication with android devices is available via Bluetooth®.

Input/ Output function

Analog signals from thermometers or light sensors can be measured simultaneously with electrical power
data via 2 analog inputs (DC voltage); when any events related to power quality occur, signals can be
transmitted to alarm devices via one digital output.
