Energy management calibration

Prerequisites

Energy Management (EM) calibration is performed to calibrate the setting (gain and offset) of AD converters

in several channels (that is, battery voltage, BSI, battery current) to get an accurate AD conversion result.

Hardware setup:

• An external power supply is needed.

• Supply 12V DC from an external power supply to CU-4 to power up the phone.

• The phone must be connected to a CU-4 control unit with a product-specific flash adapter.

Steps

1. Place the phone to the docking station adapter (CU-4 is connected to the adapter).

2. Start

Phoenix

service software.

3. Choose File→ Scan Product.

4. Choose Tuning→Energy Management Calibration.

5. To show the current values in the phone memory, click Read, and check that communication between

the phone and CU-4 works.

6. Check that the CU-4 used check box is checked.

7. Select the item(s) to be calibrated.

Note: ADC calibration has to be performed before other item(s). However, if all calibrations are

selected at the same time, there is no need to perform the ADC calibration first.

8. Click Tune.

The calibration of the selected item(s) is carried out automatically.

The candidates for the new calibration values are shown in the

Calculated values

column. If the new

calibration values seem to be acceptable (please refer to the following "Calibration value limits" table),

click Write to store the new calibration values to the phone permanent memory.
