For the loaded test should you put load on the battery ie put lights on demist etc?

I think it puts load on its self

I got 3 different test results within 1 minutes, Whether a certain time interval is required for each test？

Hello, can you check if the device is connected properly? In addition, please wait 1 minute between each test to see if the values of the equipment are consistent. If the device still can't work, please contact the tech support, they will solve the problem for you: support@topdon.com.

what does the reverse polarity protection mean?

If you accidentally connect the negative clip to the positive side of the battery and the positive clip to the negative, the device will sense the mistake and protect the circuits inside from damage.

Can I review my historical diagnostic data? how can i do that?

Hello. I have looked at mine and I cannot find any data retrieval but they do one with a printer built in for about £20 more.
