Instrument Overview
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 transmitted to PC via
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
W
SAVE
Key. Integration and demand
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
Backlight to facilitate working in dimly illuminated areas
Light & compact design
Clamp sensor type, compact and light weight design
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 real-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 instrument will be powered
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.
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.

Measurement Ranges
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 W/ Wh/ DEMAND Range.
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 WRange
(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.
Screen 1 -symbol blinks on the top
Screen 2 -symbol blinks on the middle
Screen 3 -symbol blinks on the bottom
(b) Selecting Wh or DEMAND Range
(1) Use the Keys and select the symbol while the Function switch is at the W
Range position.
(2) Press the Keys and select the Wh or DEMAND Range.
(Selecting eitherWhorDEMANDRange is impossible unless symbol is not selected.)
