• The logger must only be used as intended and in
accordance with the instructions in this manual. Failure to
do so may impair the safety features of the logger.
• Never attempt to use the logger or accessories if they
appear to be damaged or malfunctioning. Disconnect the
mains supply and contact your supplier.
• The logger is for indoor use only. Do not use in damp or
wet environments.
• Installation of this logger may expose the operator
to hazardous voltages. If in doubt, refer to a qualied
electrician.
• The mains input of the logger (see page 6) must only
be connected to an AC mains socket using the supplied
lead. Do not exceed the maximum rated input voltage
for the logger.
• The current measurement inputs must only be connected
to approved exible coil current transducers, Gemini part
number ACS-002X. Any other type of connection may
damage the logger and expose the user to hazardous
voltages.
• An earthed mains connection is required for correct
operation, not for device safety.
• When changing batteries, make sure the mains lead is
removed from the logger.
• Only use 4 x Alkaline AA batteries, observing the correct
polarity.
• The logger must only be operated with the battery cover
tted.
• The logger contains no user-serviceable parts. Do not
open (except to remove the battery cover when replacing
batteries).
• The logger contains hazardous voltages and a lithium
battery. Servicing must be carried out by an authorised
service centre only. Please contact your supplier for
further information.

The Tinytag Energy logger combines the level of
performance required by experts with the level of simplicity
required by those that are new to energy management.
The logger is ideal for monitoring building energy supply,
sections within a building or individual pieces of equipment.
Data from the Tinytag Energy Logger can be used to identify
power-hungry or inefcient equipment and peak load times,
and can highlight equipment that is left powered up or idling
unnecessarily.
The Tinytag Energy Logger provides visibility of energy
usage so that effective measures can be taken to reduce
electricity bills, lower carbon footprint and improve
environmental performance.
• Simple to use
• High accuracy
• Non-invasive
• Small size/lightweight
• Reduce energy costs
• Reduce carbon foot print
• Can be used straight out of the box
• Track down inefcient pieces of equipment

For monitoring three-phase current with a voltage reference.
In this mode the logger will be powered from the mains, and
will be able to log for six weeks before it lls its memory at
the default ve minute logging interval.
Before logging is started, the logger is in a set-up mode
where it automatically matches the voltage measurement
against the three current measurements.
Coil positioning is particularly important to allow this
automatic set-up to complete. See page 20 for examples,
and follow the prompts on the display.
Automatic set-up is complete once the prompts disappear;
recording can then be started.
Once recording, the position of the coils is no longer as
important and provided they remain around the conductors
they were congured to, the logger will measure correctly.
• Follow the on-screen prompt and plug in:
• The mains cable.
• Coils L1, L2 & L3. 

Before logging can be started the logger has to determine
which current phase the voltage reading is being derived
from.
For the automatic conguration 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 specic
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 ow, 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 congured itself, and logging has
started, the coils simply need to be kept around the correct
conductor.
