Calibration process :

Please note : This process is not required when using AUDIOROOT eSMART Li-xxWh batteries.

The 2 push buttons of the front panel are inoperative when an eSMART battery is connected to

1. Mark the battery you wish to calibrate with a number ranging from 1 to 8. The battery must be

fully charged before starting the calibration process.

2. Plug the battery on the eSMART BG-DU power distributor with a compatible power cable

(preferably leave pins 2 and 3 on the Hirose connector unused)

3. Plug all the equipment that will be used in normal operation (for example a portable mixer, a

transmitter and 2 receivers).

4. Put all 3 power switches of the eSMART BG-DU in ON position and power on all your equipment.

5. By using the 2 push buttons select the battery index that was chosen in step #1.

6. Initiate the calibration process by pushing the 2 push buttons simultaneously.

The fuel gauge will now be measuring and saving the value of the total current drawn. This process

should be ended only when the battery is empty.

In the case of a li-ion or LiFePO4 battery the calibration will stop automatically when the low

voltage protection circuit of the battery trips.

When calibrating a battery of another chemistry (SLA or Ni-Mh) the user needs to shutdown the

fuel gauge manually when the battery's voltage level gets too low in order to terminate the calibration

process correctly (for example the low voltage level of a 6 cell SLA battery is 10.5 Volts : this value can

be used to terminate the calibration process of a standard SLA battery).

The fuel gauge is now aware of the battery's total capacity. The user only needs to recall the

corresponding battery index number when connecting a fresh battery to monitor its state of charge

efficiently and accordingly.

PLEASE NOTE: A battery that has been previously calibrated must always be connected fully

charged to the eSMART BG-DU or the state of charge indications will be inaccurate.
