Start with zeroing: clean the anvils, check battery voltage, verify against gauge blocks at several points, log drift, then recalibrate or service if errors repeat.

Zero-point error in pressure transducers is corrected by venting to reference pressure, stabilizing temperature, then trimming zero output before recalibration.
Start with safety, set baseline pressure, scan lines slowly with an ultrasonic detector, tag leak points, record dB levels, repair, then verify savings with a follow-up survey.
