Today's pressure canners may have a dial gauge for indicating the pressure or a weighted gauge, for indicating or regulating the pressure.
Weighted gauges will either keep rocking gently or make a frequent jiggling noise to indicate that the correct pressure is being maintained. Read the manufacturer's instructions to know how a particular weighted gauge should rock or jiggle.
Check dial gauges for accuracy before use each year. Gauges that read high cause under-processing and may result in unsafe food. Low readings cause over processing. Pressure adjustments can be made if the gauge reads up to 2 pounds high or low. Replace gauges that differ by more than 2 pounds.
