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
1.1. SET UPSET 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
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.
Combined values will be displayed on
a graph in real-time. Real-time display
Measurements can be displayed in graphic or nu-
meric forms on Android™ devices in real-time via
Bluetooth®communication.
Remote checking of measurements is possible
without accessing KEW6305.
Max communication distance: 10m

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.

Before connecting with the sensors KEW 8133 or KEW 8135, confirm that the
internal firmware version is later than the one listed in the table below.
The latest firmware is available on our website.
When using the sensor KEW 8135, confirm the serial number of the tester KEW
6305 is later than that is listed in the table below.
If your KEW 6305 has an earlier serial number than the one listed above, accuracy
will not be guaranteed when two or more KEW 8135 are connected with KEW 6305.
Supported serial numbers 8369312 or later

Can you close your distribution board door during surveys?
The KEW6305 facilitates safe testing by being extremely com-
pact and with two clever option extras: a magnetic case for
attaching it to the sides of metal enclosures and a power supply
adaptor which takes the power for the instrument from the sup-
ply being measured.
