OK I have had several responses and 110F is low as I expected. Wonder if I am being faked out? Perhaps by an inner oven and I am only reading the outside of the outer oven. The Older URQ10 and newer URQ23 do have 2 ovens. The meter switch for test is only labeled 1-9. no other clues to the function. I noticed 2 positions change with warm up. Sort of supports the 2 oven theory. Really do not want to take what might be the outer oven off to put the probe in. Thanks everyone. Paul WB8TSL
