6.2. Power Consumption Measurement for VCC or in ALP Mode
Before measuring the power consumption of VCC or in ALP mode, you must connect the components to
the EVB to ensure that the module can communicate and fix it normally. See
Chapter 4.1 Test via QGNSS
Detailed steps for measuring power consumption of VCC or in ALP mode with an ammeter:
Step 1:
Switch off the power supply (S201) of the module and pull out the VCC_MODULE jumper cap
(J102). Connect the ammeter in series to the pins of J102 as shown below.
Step 2:
Switch on the power supply (S201) of the module and read the ammeter.

Figure 12: Measured with Ammeter for VCC or in ALP Mode
Detailed steps for measuring power consumption of VCC or in ALP mode with a power consumption meter:
Step 1:
Switch off the power supply (S201) of the module and pull out the VCC_MODULE jumper cap
(J102). Make sure the positive pole of the power consumption meter is to be connected to pin 2
(without arrow silkscreen) of J102, and the negative pole is connected to GND.
Step 2:
Switch on the power supply (S201) of the module and read the power consumption meter.
