Pointer Adjustment | How to Adjust a Pressure Gauge Needle

There are a number of ways that mechanical dial pressure gauges can lose calibration or be thrown off their zero. In this video we demonstrate how to adjust (or re-zero) a pointer of a repairable pressure gauge to return it back to calibration.

guage I'm trying to fix doesn't have any "adjustment" spots on the needle....it's just a black needle with a silver circle with a tiny hole in the middle. I kinda been turning it around multiple times both ways and can get it down to zero but then it's stiff and won't go past like 70psi without having to push it further with your fingers . And then it won't drop back to zero after that point.....might just have boss buy me a new one

There are some pointers that do not have an adjustment screw. These are typically on less expensive or non-repairable gauges. If you are able to access the pointer, you will need to remove the pointer with a pointer jack and re-stake it in the appropriate position. The best method is to pressurize the gauge to mid-scale and set the pointer. After staking on the pointer, you should tug at the pointer to verify it does not come off. If so, this will be the be staked on with more force. Though this isn’t a practice used with Reotemp, some manufacturers use adhesive to keep the pointer on the shaft.

How to open that gauge

IMPORTANT! Your gauge must be frequently calibrated! No one talks about this! It is vital. Dropping your gauge, using your gauge, anything can maladjust it. If you don’t have it gauged you have no idea if the correct pressure is being used to kill C. Botulinum spores. You are gambling with lives. Google USDA gauge calibration in your area. It is usually done at a college or university. It takes 15 minutes and costs about 5 dollars. Find out from your canner manufacturer or the USDA on how often your gauge must be calibrated!!! Happy, safe canning!!!
