Quick Answer
If using a weighted gauge, you don't need to adjust the pressure; however, always refer to your canner's instructions and local regulations for specific guidelines.
Understanding Weighted Gauges
Weighted gauges are used on some canners to regulate pressure. They work by displacing water in the canner with a weighted device, which increases the pressure as the weight is submerged. These gauges are often used on older canners or those with specific pressure requirements.
Setting the Pressure
When using a weighted gauge, you need to ensure the weight is properly calibrated for the type of canning you’re doing. Typically, a weighted gauge will be set for a specific pressure range, such as 10-15 PSI. You’ll need to adjust the weight accordingly to achieve the correct pressure. For example, if your recipe calls for 12 PSI, you’ll need to adjust the weight to ensure the gauge reads 12 PSI.
Pressure Considerations for Canning Meat
When canning meat, it’s essential to maintain a consistent pressure to prevent spoilage and ensure the meat is properly sterilized. A weighted gauge can help you achieve this consistency, but it’s crucial to follow a tested recipe and local regulations. For example, the USDA recommends a minimum pressure of 10 PSI for canning meat, but some recipes may require higher pressures. Always consult your canner’s instructions and local guidelines before proceeding with canning meat.
