I have not gotten a positive yet but it should be 2 vertical lines if positive. One line in the test area if a negative. This product is just like the 2 line tests from walmart, walgreens, cvs etc. It is NOT a + positive test.

When facing the front of the meter, the port on the left is negative (-) while the port on the right is positive (+). In other words, if you apply a positive pressure to the left port the reading is negative and if you apply a positive pressure to the right port the reading is positive.

2 posts in middle are for positive/negative DC Input. The two outside posts are for positive/negative DC output to motor. Switch just reverses polarity on those 2 posts.

There is two stray wires for positive and negative. You can connect it to batteries. Connect it to a 12 volt source i.e. inside cab lights.
