Pressure Gauge Hands Blocked by Pin

Why are the dial hands underneath the metal pin? I'm a security guard and I am tasked with doing rounds of mechanical rooms. I've been asked to look at these specific water pressure dials and examine whether the hands are stable and too inform the administration of the building if they are not. I noticed that two of the hands are underneath the metal pin on which they should rest if they were at zero. I'm very ignorant in plumbing, but is it supposed to be like this? Why is it like that? Doesn't it make the hand impossible to rise above 0 since it's blocked by that pin? 150 200 250 300 100 50 0 800 1200 1600 2000 400 PEM SER WINTERS kPa www.winters.com

A pressure gauge is shown with its needles positioned beneath the metal stop pin near zero. The poster asks whether this is normal, not realizing that the gauge’s internal mechanism and needle arrangement make the apparent obstruction harmless. The image is used as a humorous reaction to confident confusion or overthinking a simple mechanical detail.
