It took me a while to figure out how to get my trip1 meter to work. I had to actually read the manual. Trip meter is controlled from the STP function, which is the next function. The STP function is described as shown in the photo from the manual. I spent a lot of time trying to figure out what I was supposed to do for the 1st step, 2nd step, 3rd step, 4th step, and 5th step functions. Push the button again when the counter goes to it? Can anyone explain what the manual is saying? Is this just an explanation of the function is doing internally?
