Datasheet

A simple and inexpensive way for Cost Savings through Energy monitoring
Rotate the Rotary switch to SET UP. All the instrument settings can be easily
selected by using instrument buttons. All the settings can also be selected by
connecting KEW6305 to a PC via USB or Bluetooth.
Starting from OFF position and rotating the Rotary switch clockwise,
KEW6305 is ready to use in 3 simple steps
1. SET UP
Rotate the Rotary switch to WIRING CHECK. The Automatic Wiring check func-
tion will prevent incorrect connections, check the connections and display the
results on the LCD.
Error messages appear on display to indicate wrong orientation of Clamp sen-
sors or incorrect connections.
Everything is OK Error is found
Max amount of data (reference)
Rotate the Rotary switch to W/Wh/DEMAND. The instrument can perform
Instantaneous, Integration and DEMAND measurements.
START / STOP button to start / stop recording
Two units of KEW6305 can be used simultaneously and perform synchronous measurements on 2 power lines.
PC software application can synchronize recording intervals and internal clocks of two KEW6305 via Bluetooth
communication or USB port. Measurements will be transmitted to the PC.
Parameters such as active, reactive and apparent power; active, reactive and apparent energy and demand will
be graphically displayed in real-time.
* For wireless communication, a PC with Bluetooth function is required.

Data saved on an SD card or internal memory of KEW6305 can be directly transferred to a computer
via USB. USB ver. 2.0 is supported.

SD cards up to 2GB can be used.
*in case the SD card is empty
Not only the total power and power factor are shown but also the breakdown related to each phase
The last 10 measurements saved on SD card or internal memory are displayed
on the LCD.
This function allows quick checks of the recorded data without using a PC.
In case of a mains blackout, the power to the instrument is automatically supplied by the Alkaline batteries (Max
continuous measurement: 15 hours)
In the case of both power supplies to the instrument being interrupted, recorded data just before the event of the
interruption will be saved.
Rechargeable nickel-hydrogen batteries can be used
Automatic creation of graph and list from recorded data.
Uniform management of setting and recorded data acquired from multiple devices.
Data can be expressed in crude oil and CO

equivalent values in the report.
Combined values will be displayed on
a graph in real-time.
Tablet device
Real-time display
Measurements can be displayed in graphic or
numeric forms on Android devices in real-time via
Bluetooth communication.
Remote checking of measurements is possible
without accessing KEW6305.
Max communication distance: 10m
Supporting Android ver. 3.0 - 3.2
