hi:
I am now using nrf52832 development bracelet, I have nRF52 DK and nRF6707,Using the latest version of PPK software testing，I am now ready to use PPK to test the power consumption of the product.，The connection method is shown in Figure 1, Figure 2 is an enlargement of the upper left corner of Figure 1,Figure 3 is a software diagram of PPK,I have several questions:
1.I now use the nRF52 DK to test the external device's power consumption. The wiring is based on the connection method on page 19 of the Power Profiler Kit User Guide. The nRF52 DK should not require cut SB9, short SB11 or SB12? Because I do not test on nRF 52 DK. right?
2.Please see Figure 2. The positive pole of P16 is connected to the VCC of the tested product. VCC should not refer to the positive pole of the battery？
3.see Figure 3 and Figure4,When using PPK to test the power consumption of the product, the peak current is relatively high. What is the need to set in the actual test process? Press "CTRL + ALT + SHIFT + A" will appear "Switch levels" settings, how to set?
4.Resistor Calibration need to set?
5.If the PPK firmware needs to be updated, the PPK's host computer should be prompted to upgrade?
6.Which demo has official power consumption test instructions?
7.Does nordic have documentation on reducing power consumption?
8.see Figure 5:I used ppk to test the power consumption of the heart rate sensor, the maximum peak current reached 80mA, PPK can only measure the current of 70mA, why measured 80mA?
think you .
