DA16200 DA16600 FreeRTOS Getting Started Guide
In the H/W Settings tab of the new prof ile, the Voltage (1.1 V - 3.3V) f ield is typically empty and the
Calibration Offset (mA) f ield is zero. Apply the correct voltage as conf igured in the Power Meter
LDO (typically, it is 3.3 V). The Calibration of f set (mA) will be f illed automatically with a calculated
value. This value is good enough to measure with ±2% accuracy, so in most cases we can leave it
as is. Check the multiplication f actor. For DA16200/DA16600, it should be 155.
The user can set a maximum scale f or the wavef orm window optionally, since there are large peaks
on wakeup f rom sleep (charging capacitors) generally. Thus, the usef ul part of the signal is
compressed to a very small area. To set a maximum scale f or the wavef orm window, open the Chart
Settings tab as shown in
Figure 57
and f or Plot Current1, set the MAX scale of Current (mA) to 10
mA. Note that this does not af f ect anything to the accuracy of the measurement. It can only zoom the
wavef orm, which is presented in the viewer. Click Apply and return to the measurement window.

Measurements
In the measurement window as shown in
Figure
58, click Initialize at the bottom lef t (this step is only
needed at the f irst communication with the A/D converter). Click Start.

Select the Power Profiler > Measure menu on the window, users can measure the current
consumption in the desired section as peak and average by using a mouse.
