Sorry, I have no idea what your asking but checking the tolerance on my normal floor pump with a non digital gauge it's accurate enough for me lol. I bought it for just throwing in the bag for when it's needed as I only own a floor pump and a shock pump and I don't carry the floor pump around for obvious reasons
anyone who's ever had to inflate a tyre with a shock pump out and about will know it takes a while lol so was looking for a digital gauge pump and these type of things were generated in my search.... Thought 
why not ? And here we are
