Thank you for purchasing e-STATION TWO-METER. Please read this entire operating manual completely and attentively as it contains
important information and safety notes, therefore you need to keep this manual in a safe place, and be sure to pass it on to the new owner
if you ever dispose of TWO-METER.
TWO-METER is a very sophisticated electronic device that controlled by high performance microprocessor and precise resistors. It has
three functions of ‘watt-meter’, ‘battery checker’ and self-balancer. Those functions are essential for electric flyers to ensure safe battery
condition and to measure the electric consumptions of the power system. And also, the built-in self-balancer can equalize the individual
voltages instantly. TWO-METER can handle all types of Lithium batteries(LiPo, LiIo, LiFe) consisting of series-wired cells, but the battery
pack has to have a balancing plug for checking voltages.
When connect the individual
connection cable to TWO-METER, it
should be matched with the plug of
the battery pack. Suitable adaptor
boards are available for various types
of connector from the battery
manufacturers.
(for PolyQuest EAC123, for
Kokam/Graupner/Robbe EAC128, for
FlightPower/ThunderPower EAC129,
and for Align EAC124)
Basic operation
Battery checker program
This feature can be used to check the residual battery capacity and the voltage of individual
cells.
-. Select the program by pressing ‘SELECT’ button to suit the type of battery being measured.
-. And press ‘ENTER’ to go to the next screen.
-. There are two programs which are voltage checker and self-balancing. Select ‘LiPo Check’
program using ‘SELECT’ button and press ‘ENTER’.
TWO-METER is activated when the battery is connected to the unit. For the battery checker
function, connect the battery pack to the individual port via a suitable adaptor board, or connect the
battery to the cable of ‘Power source’ for watt meter.

It shows the type of battery and number of cell-count at upper right, and output voltage. At lower
line, it displays the residual capacity at percentage and visual graph.
The individual voltages are shown from the first cell at upper right.

If the voltage are out of balance, it warns and shows the voltage difference from the highest to
lowest one. You need to let them balanced, or check the cells and cables carefully.

Self-balancing program
This program can equalize the individual voltages to their lowest one.
-. Select the matched type of Lithium battery using ‘SELECT’ button.
-. And press ‘ENTER’ to start to balance .

Balancing
As the balancing job goes on, you can see the individual voltage by pressing ‘ENTER’ button.
When the balancing job is completed, the beep sounds 20 times.
(You can set the beep sound ‘OFF’ by pressing ‘SELECT’ button for more than three seconds. Or
you can set it ‘ON’ by doing the job again. The default is ‘ON’.)
To protect the battery from the over-discharge, there are minimum
voltages to be balanced for each type of Lithium batteries. If the any
individual voltage is lower than the limit, there shows an error message.
LiPo/LiIo: 3.0V, LiFe: 2.0V
