The calibration is performed in two steps:
Zero current calibration – You measure the level on IMEAS at idling when there is no charger
connected, i.e. DCIO open.
High current calibration – You do the same measuring as above, but with DCIO high and set on
a certain voltage and current limited.
14.2 How to perform a current calibration
Start the phone in the test program.
Go to Logic \Current calibration.
When you start the Current calibration, the window below Fig. 14.2. is telling you to set the
battery voltage for dummy battery to +5.8 V
When you have done that, click on OK.
The next window Fig. 14.3 shows the result of the calibration.
A new window Fig. 14.4. is shown telling you to keep the battery voltage to +5.8 V
the DCIO-voltage on the power supplier to +8.7 V
Use the same power supplier if it is possible to set two different voltages, otherwise use two
power suppliers.
One way to connect DCIO to the phone is to cut a cable from a battery charger and connect it to
the power supplier.

at the power supplier and keep DCIO open.
