3. Run a free running capture for a few seconds and note down the number in
the “
Avg Current
(mA)
” box (
). Note that the last digits of the number keep changing slowly due to
temperature drift. It is important to periodically execute the calibration steps.

4. Finally, put this average value with a negative sign in
the “
Calibration Offset (mA)
” box. CTRL-C
and CTRL-V also works.

5. Re-insert the daughterboard or restore the jumper removed from J4 in the previous step.
NOTE
Please notice that the value in the
Voltage
box is 3 V. This is a typical value used across the industry for
comparing BLE power measurements. Therefore, the power configuration on DA14531 PRO-MB must be
updated accordingly (J5: 2-4).
