recording paper, at which time the pen will pause at the outmost temperature graduation mark
on the recording paper (this graduation mark is not necessarily with temperature value, but it
must be the outmost graduation mark). If the pen does not pause in this position, you may
adjust its position by using 1# or 2# arrow within 5s to make the penpoint align with the
outmost graduation mark. If you don’t finishing the adjustment of pen within 5s, please repeat

The glycerite bottle with thermocouple is stored in the freezer for about 4h. When the
temperature of glycerite in the bottle is identical with the freezer’s internal temperature,
compare temperature values of the standard thermocouple and recorder, if they are not the
same, you may adjust the recorder’s recorded value by using the adjusting buttons on the left
(1#) or right (2#) of panel to make it in conformity with the thermocouple’s indicated value.
