Can you show me where 5hg is on my pump pics included

Hi all. I was at a sex store with my girlfriend tonight. I walked over and saw the penis pumps and bought one impulsively. I was going to wait and get a LeLuv but figured I would spend a little bit less now just to see if I even enjoy pumping.

The problem is the measurement gauge on my pump isn’t clear to me. It shows mmHG and MPa.

Can you tell me where 5HG is on my pump gauge? Is it the BLUE 500 that the gauge meter is covering up in the photo? I’m sorry if this is a stupid question I just do not want to hurt myself and I want to go slowly so I want to just do around 3hg my first time but I just want to make sure I know where 5HG is so in the future I know that is the spot I do not ever go past. I only ask because the blue 500 seems to be a lot of pressure but maybe that’s just because I’m new and I have NOT used it yet. I plan to try it later tonight once I get confirmation on where 5HG is.

Here is a photo of my pump gauge

I am sorry for the double post but it seems as if 127mmHG would be the equivalent of 5inHG which is what most people on here are using. So It seems as long as I keep my pressure around 120mmHG (the 6th small blue line right under 0.02MPa) I should be fine. If anyone could verify I would be grateful! Thank you!

You’ve got the math: 127mmHg = 5inHg, so I am confirming your calculation.

And 120 is pretty close and an easy reference mark.

Thank you! I greatly appreciate it. Have a wonderful day.
