NOTE: The “Zones” on the indicator are approximations for the different
altitudes. Before using the canner please follow the instructions below to
calibrate the indicator for your exact altitude. This testing procedure is
very important and will enable you to know precisely when to start your
processing time to avoid under or over processing of your canned foods.
Temperature Indicator Test
The Temperature Indicator should be tested and calibrated prior to initial
and seasonal use of your VICTORIO Steam Canner.
• Follow canner instructions on p. 7, except skip steps 3 & 4 and use only
four one-quart jars filled with water, the jars do not need lids. The four
jars simulate the contents of your canner in actual use but enable it to
get up to temperature quicker.
• It will take about 20 – 45 minutes to come up to full temperature and
complete the test. The time it takes depends upon the stove that is used
and heat that is applied.
• If the lid starts lifting up, rattling or spitting water from around the
edges, this is an indication that it is almost up to temperature and you
need to slowly turn the heat down until these actions stop.
• Continue to watch the indicator until the red needle stops rising. The
indicator should reach the green area for your “Zone” but can vary
from just reaching the green area to going far inside it. This is because
the “Zones” are approximate and your exact altitude will affect the
maximum position of the indicator.
• Record this maximum point by marking it on the indicator knob,
making a note or taking a picture. This is the point at which your
canner is up to boiling temperature and it is safe to start the processing
time. To ensure that each batch is properly processed, be sure to wait to
start the processing time until the indicator reaches this point.
• For best results, this test should be repeated each year before you begin
your canning, note any changes in the indicator reading from the prior
year. This test will also need to be done each time your canner is used
in a different location, as elevation differences will cause the indicator
to read differently.
