Before you begin
EM (Energy Management) calibration is performed to calibrate the setting (gain and offset) of AD converters in
several channels (that is, battery voltage, BSI, charger voltage, charger current) to get an accurate AD conversion
result.
HW setup:
• An external power supply is needed.
• The mobile device must be connected to JBV-1 (docking station) with DA-44 (docking station adapter).
a Connect SCB-3 (DC-DC cable) between JBV-1 and charger connector of phone for charger channel
calibration.
b Supply 11-16V DC from an external power supply to JBV-1 to power up phone.
Phoenix SW setup:
• Start Phoenix service software.
• Select FBUS connection.
• Choose: Main -> Product -> RM-51.
• Choose: Tuning -> Energy Management Calibration.
Steps
1. Select "Read" to show the current values in the phone memory, and then check that the communication
with the phone works.
2. Select "JBV-1 used" check box under the options menu.
3. Select the item(s) you try to calibrate.
Note:
ADC has to be calibrated before other item(s). If the ADC value is correct or you calibrate ADC and
other items at the same time, that's OK.
