Battery Calibration
9.4.1
Preliminaries
There are two procedures associated with battery calibration, battery temperature and battery voltage.
1.
Connect the RF Adaptor / Baseband Jig, telephone and PC as shown in the diagram below.
Figure 9.3: Battery calibration test connections
2.
Set the Interface box to
POWER ON, IGN
and
EXT PWR OFF
.
3.
With the CB2000 software running, select the
‘Baseband Calibration’
button.
4.
Select the
Battery Calibration
tab.
5.
The Battery Calibration window is divided into three areas:
a) Semi-Auto Voltage Calibration
b) Temperature Calibration.
c) Charging Calibration.
9.4.2
Semi-Auto Battery Calibration
1.
Ensure that VBAT is set to 3.7 V.
2.
Carry out the instructions described in the main dialogue window. Note that the VBAT HIGH voltage is 4.2 V and that VBAT
LOW voltage is 3.0 V.
9.4.3.
Temperature Calibration
1.
Ensure that VBAT is set to 3.7 V.
2.
Carry out the instructions described in the main dialogue window.
3.
If at any time the message
“Temperature Cal failed”
, the calibration procedure has failed. Check all test equipment
connections and that the correct resistor has been selected before suspecting a problem with the handset. Further
information may be displayed in the dialogue window.
4.
When the message
“Temperature Cal Done”
is displayed in the dialogue window, the calibration procedure has been
completed.
9.4.4
Charging Calibration
1.
On the Interface Box, ensure that the
EXT PWR
switch is
ON
. Check that the RF Adaptor / Baseband Jig 82 Ohms switch
is set to
ON
.
2.
Carry out the instructions described in the main dialogue window.
3.
When prompted, measure the RF Adaptor / Baseband Jig voltage by connecting a voltmeter to the terminals on the top of
the RF Adaptor / Baseband Jig.
4.
If at any time the message
“Charging Cal failed”
, the calibration procedure has failed. Check all test equipment
connections and that the correct resistor has been selected before suspecting a problem with the handset. Further
information may be displayed in the dialogue window.
5.
When the message
“Charging Cal Done”
is displayed in the dialogue window, the calibration procedure has been
completed.
