About the concept of load and power supply:
1. During discharge: batteries, switching power supplies, and transformers are power sources, and resistors, lamps, motors, and electrical equipment are loads.
2. When charging: the charger, generator, solar energy are the power sources, and the rechargeable battery and the storage battery are the loads.
Wiring:
Black line (thick): vacant or buck circuit (module) negative
Red line (thick): power supply-
Black line (thin): COM, common measuring
Red line (thin): PW+, measuring terminal voltage input positive
Yellow line (thin): IN+, current input+
(Please refer to the wiring diagrams for more details)

Les volts fonctionnent, pas les amperes.

This appears to be version 2 of this unit, there were no instructions supplied and although this was supplied as a dual pack, neither unit worked. When connected as described on the Amazon page the current meter displayed 98.3A, impressive for a unit rated for 10A! Especially as this was without any load connected. When a load was connected as described the load didn't function and the current reading didn't alter. I bought this on an impulse following an advertising email from Amazon on my phone. Lesson leant!
