In this video we are detecting which multi tester works properly. Packaging was very bad. When I opened the parcel there were only multi tester boxes multi testers within and nothing like a fall defender or something soft thing to protect things from falling down.
Please be free to write your opinion in comment below.
We think that there are two different cases:
1. The multi tester which is on the left side is not working properly because when we put batteries in, it can't turn on unlike the second tester.
2. More likely we think the tester on the left side is damaged why it's more sensitive to the low amperage batteries why it no longer turns on again until I reinserting batteries again while multi tester is on voltage mode. (I bought new batteries, tried several types of batteries: Sony, ABC, Toshiba, but the result was the same in all three cases).
