     1        A.  No, the temperature was not raised.  They have always
     2        been 350.
     3
     4   Q.   It has always been 350?
     5        A.  Yes.
     6
     7   Q.   So how is it acceptable to have the front of the grill at
     8        between 325 and 340?
     9        A.  OK.  This is what I tried to explain yesterday, that
    10        with the set-up of a gas grill to ensure that it functions
    11        correctly throughout the day, you have to establish that
    12        the air flows are working correctly.  In doing this at the
    13        commencement of business at the beginning of the day, you
    14        have to do the check at a certain time.  If you have this
    15        heat ratio before you have cooked any product on it, then
    16        you know that grill will be working correctly.  After that
    17        if you were to check the grill throughout the day, you
    18        would expect to get 350 anywhere on the surface.
    19
    20   Q.   It would go up after the test?
    21        A.  Yes, well, it would -- I think the -- we were still 350
    22        that we wanted on the surface, but to check that the grill
    23        was in perfect working order, that the air flows were
    24        working correctly, I believe that you had to do this test
    25        to establish that.  And that is why you have the
    26        differences.  What happens is that the flue at the back
    27        draws the heat along the grill surface so that the back of
    28        the grill would naturally be hotter.

    30   MR. JUSTICE BELL:  I think what is being put to you, when you
    31        are doing those calibration tests, so you have got 325 to
    32        340 at the front and so on, what is the dial actually
    33        showing?  Is it showing 350 which is the grill temperature
    34        on page 545 for gas ---
    35        A.  I think -----
    36
    37   Q.   -- the calibration as I understand it, is making sure that
    38        your indication of temperature, weight, whatever it is, is
    39        accurate?
    40        A.  That is correct.
    41
    42   Q.   Speed, whatever it is?
    43        A.  That this is like a calibration of the flow of heat
    44        across that particular grill surface.
    45
    46   Q.   I understand that.
    47        A.  So, if it is set -----
    48
    49   Q.   But, presumably, in relation to the dial, or whatever it
    50        is, on the front of the machine which is telling you what 
    51        the temperature is, or is that a complete misunderstanding? 
    52        A.  Although I cannot remember the procedures in detail, 
    53        I believe that you would have it set at 350 on the front,
    54        and it was specifically after a length of time, after
    55        switching that grill on, you would check and you precisely
    56        had to do it at these positions at this time, before you
    57        cooked any product on it, to work to know that you had the
    58        grill, the gas setting set correctly.
    59
    60   Q.   The assumption being that by the time you start cooking on
