That could well be a very good Chinese unit that will comes with instructions in somewhat incomprehensible "Chiinglish".  Good luck with that 😅.

I will let you know just what dialect the instructions are printed in when the unit arrives.

Glad to say that the meter arrived today, and the instruction are in plain English. I just have to get used to the unit now.

We carry a cheap multimeter for fault finding as others have said. One did fail, but at that price replacement didn’t hurt. However, there’s a high risk of corrosion on caravan connections due to dampness in storage and only periodic use. A corroded terminal may allow a full 12V reading but won’t pass enough current to operate its load. For testing you need a car lightbulb  with one side wired to a spike and the other to a crocodile clip for earthing. You can buy a proprietary tester cheaply, though an old fashioned car bulb with its higher wattage may be better for identifying high resistance in corroded terminals. For short circuits, switch off the suspect circuit, then switch on a functioning 12v light. Briefly switch the suspect on while watching for any dimming of the functioning light. If it does dim, then the fault is drawing power.
