Preface

● Preface This Quick manual is a simpliﬁed version of the full instruction manual which can be found in the supplied

CD-ROM. This manual is intended only as a handy reference guide and should only be used after having read the full instruction manual which contains full details on each function of this instrument and the items contained in the package.

● Precautions

The instruction manual (full manual) contains warnings and safety procedures which have to be

observed to ensure safe operation of the instrument and maintain it in a safe condition. Thus, these operating instructions have to be read prior to using the instrument.

1. Instrument Overview

Features

This is a digital Power meter that can be used for various wiring systems and can measure up to 3 systems on single-phase 2-wire circuit. That is, this instrument does the jobs of three just by one. It can be used for measurements of instantaneous, integration and also demand values.

Measured data can be saved in SD card or the internal memory, and the data can be t USB. Measured data can be checked on android devices in real-time by using Bluetooth function.

Safety construction

Designed to meet the international safety standard IEC 61010-1 CAT.III 600V

Wiring conﬁgration

KEW6305 supports: Single-phase 2-wire, Single-phase 3-wire, Three-phase 3-wire and Three-phase

4-wire

Measurement and calculation

KEW6305 measures voltage (RMS), current (RMS), active power, frequency and calculates reactive/

apparent power, power factor, neutral current (Three-phase 4-wire only) and active/ reactive/ apparent energy.

Demand measurement

Electricity consumption can be easily monitored so as not to exceed the target maximum demand

values.

Saving data

Instantaneous values can be saved every time pressing the

values can be saved for various periods from 1 second up to 1 hour. The maximum, minimum and average values of instantaneous values during each cycle can also be saved.

Dual power supply system

KEW6305 operates either with an AC power supply or with batteries. In the event of interruption,

while operating with an AC power supply, power to the instrument is automatically restored by the batteries in the instrument.

Large display

Up to 3 measured items can be displayed on the large screen simultaneously. (e.g. voltage, current and active power)

Backlight

SAVE

ransmitted to PC via

Application

Data in the internal memory and in SD card can be transferred to PC using USB connection or SD

slot. The supplied PC software application enables easy settings of the instrument and analysis of the saved data from PC, moreover, can synchronize recording intervals and internal clocks of two KEW6305 to perform synchronous measurement. Measured data can be checked on android devices in r

eal-time via Bluetooth communication.

Preparations

3. Preparations

Battery

KEW6305 operates either an AC power supply or batteries. Capable of performing measurements in an event of AC power interruption, power to the instrument is automatically restored by the batteries installed in the instrument. Size AA alkaline dry-cell batteries (LR6) can be used.

If an AC power supply is interrupted and batteries have not been installed, the instr off and the measuring data may be lost.

Indication on screen

Symbol of power supply displayed on each measurement screen changes as follows.

< During AC power supply operation > < During battery operation > AC power supply symbol ( ) appears. Battery symbol ( ) appears.

● Battery condition Battery symbol changes as follows depending on battery condition.

Battery operating time

For approx. 15 hours, with new alkaline batteries. * It is reference time and will be shortened if using the backlight or

Bluetooth function.

ument will be powered

Batteries are exhausted. (Accuracy of readings cannot be guaranteed.) Depending on the states of measurement, instrument operates as follows automatically. * while saving instantaneous value data (Files are opened.)

-> Close the open ﬁles. (Data will be saved.) * while measuring integration/ demand values

-> Force-quit measurements. (Data will be saved.)

How to install batteries

Install batteries in correct polarity as marked inside. Remove all the batteries if the instrument is to be stored and will not be in use for a long period.

5. Measurement Ranges

KEW6305 can perform the following three different measurements. (a) Instantaneous value measurement (W Range) (b) Integration value measurement (Wh Range) (c) Demand measurement (DEMAND Range)

Select a desirable Range according to the steps below.

1. Set the Function Switch to

Set the switch to W/ Wh/ DEMAND position.

2. Select a Range Any one of following symbols blinks on the LCD to show which Range has been selected.

e.g.: When Wh Range is selected, symbol blinks.

(a) Selecting W Range (1) Use the Keys and select the  W  symbol on the LCD. (2) Then use the Keys to switch screens (1- 3) to be displayed.
