Set-up
(cont.)
•
Clip the coils around the correct conductors. For
recommendations on coil positioning, see page 20.
•
Wait for the logger to complete a self check, adjusting
the position of coils if prompted. For information on
screen messages, see page 20.
•
In the event that the automatic configuration fails, the
logger can be configured manually. For information on
manually configuring the data logger, see page 24.
•
Read values from the screen, pressing the scroll
button to step through the current, voltage and
power and power factor readings.
Data Logging
•
Press and hold the Record button until the logger
confirms it is recording.

Positioning Coils
Automatic Configuration
Before logging can be started the logger has to determine
which current phase the voltage reading is being derived
from.
For the automatic configuration to work successfully, the
current coils need to be separated correctly.
Connecting Coils
The three supplied coils are interchangeable and can be
plugged into any socket (they are not calibrated to a specific
socket or phase).
Ensure, where possible, that coils are connected around
the correct conductor, pairing any colour indicators on the
conductors with the appropriate socket on the logger.
The orientation of the coil, with regard to the direction of
the current flow, is not important and coils can be connected
around a conductor either way around.
On the following page is a table offering some guidance on
good and bad coil positioning for the set-up.
Once the logger has configured itself, and logging has
started, the coils simply need to be kept around the correct
conductor.
If Automatic Detection Fails
If the logger cannot automatically configure it will display
prompts to guide the user what to do (see page 24).
