The easy way to check is to put a glass bowl of water in the oven and

(in boiling water) Oven thermostats are notoriously inaccurate, As they
age the oven runs hotter than the set temperature

I'd not guarantee that an oven which reads OK at 100C is going to be
correct at 180C.

Well, no, but boiling water is the nearest reasonably accurate and
achievable reference point available to the average householder. If it
doesn't read 100°C it suggests something wrong with the probe T/C or
the multimeter calibration.

Lead is easy to get hold of and melts at 327'C which sorts out the
top-end calibration nicely.

"When constituencies are small their elected representatives must concern themselves with
the local interests of their constituents. When political representatives are distant and
faceless, on the other hand, and represent vast numbers of unknown constituents, they
represent not their constituents, but special interest groups whose lobbyists are numerous
and ever present. Typically in Europe a technocrat is an ex-politician or a civil servant.
He is unelected, virtually impossible to dislodge during his term of employment and has
been granted extensive executive and even legislative power without popular mandate and
without being directly answerable to the people whose interests he falsely purports to
represent."
