6. Weight Input Function.
This function makes
it possible to enter the weights of the samples
so that the apparatus can make a calculation
after the weights entered at the end of the
test. When entering a weight value, the
numbers will start on the operators left and
scroll to the right as additional numbers are
entered. To enter the desired value it may be
required to enter a number of “Zeros” after the
value has been entered. The standard number
of significant figures is shown below:
XX.XXXXX G
For example, to enter 2.45 G, the user must
enter 2, then 4, then 5 followed by three
Zeros. This places the two (2) in the single
digit place resulting in the desired value.
7. Set Point Function.
This function allows the
user to input the idle set point temperature of
the furnace between tests. This value is
limited to the range from 20 to 80°C
8. Standby Function.
This function allows the
user to shut down the apparatus via the
control panel without having to switch off the
