If a gauge reading is outside the 3% tolerance, what action should be taken?

Gauges must stay within their specified tolerance to ensure readings are accurate. When a gauge reads outside the 3% tolerance, it’s considered out of spec, and you can’t rely on its measurement. In safety-critical equipment like fire extinguishers, this unreliability means you should replace the gauge with a new, properly calibrated unit to ensure readings reflect the true pressure. Recalibrating might seem to fix the issue, but once a gauge is out of tolerance, wear or damage can prevent reliable restoration of accuracy, and replacing it is the safer, more dependable option. Continuing testing or ignoring the result could lead to undetected pressure problems and potential equipment failure when needed.
