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 ine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 eective measures can be taken to reduce
electricity bills, lower carbon footprint and improve
environmental performance.

12 Modes of Operation:
Three Phase Current and Voltage
17
Set-up
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.

12.1 Modes of Operation:
Three Phase Current and Voltage
19
Positioning Coils
Automatic Conguration
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 oering 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.
If Automatic Detection Fails
If the logger cannot automatically congure it will display
prompts to guide the user what to do (see page 24).

12.1 Modes of Operation:
Three Phase Current and Voltage
20
Positioning Coils
Care should be taken when positioning coils during the set
up of the logger to ensure they are well spaced, don’t
overlap or are placed too closely to neighbouring
conductors. Poor positioning of coils can prevent the logger
conguring automatically.
If the conductors are close together, coils can be angled
around conductors.
The coil around the blue conductor is too close to the yellow
conductor. Ensure that coils are not positioned too closely to
neighbouring conductors.
