Power Consumption Test Guide
3.2.1. Test Tools
The following are the equipment and tools needed for the power consumption test:
⚫
HCM111Z TE-B
⚫
DC power analyzer
⚫
Wire, soldering iron, tin wire, and wire stripping pliers, etc. to weld the power supply cord on TE-B.
This power consumption test guide is based on Keysight's N6705C DC power analyzer for testing.
3.2.2. Modify TE-B
If you use the TE-B to test the power consumption of the HCM111Z, you need to modify the TE-B as
follows:
1. Remove R0202 (0
Ω resistor) to connect the USB power supply;
2. Solder two wires to the two pins of J0206. One wire is used as VBAT (pin 1) and the other is used as
GND (pin 2), so that the external power supply can supply power to the module separately.
