In a new profile, the
“
Voltage
” box in the “
H/W Settings
” is typically empty and the “
Calibration
Offset
” is zero. Apply the correct voltage as configured in the PRO-MB LDO (typically, it is 3.3 V).
The calibration offset (mA) will be filled automatically with a calculated value. This value is good
enough for measuring with ±2% accuracy, so in most cases we can leave it as is.
Check the multiplication factor. For DA14531 it should be
100
.
Optionally, set a max scale for the waveform window, because typically there are large peaks on
wake-up from sleep (charging capacitors), so the useful part of the signal is compressed to a very
small area. To set a max scale for the waveform window, access the
“
Chart Settings
” tab (
and set the max scale of “
Current1
” to 10 mA. Note that this does not affect in any way the
