Time 1 and 2
Each the Temperature 1 and 2 setting
can have a set period of time� Time 1 or
2 is the time during which the sample
will be dried at each temperature before
advancing to the next temperature�
Once the time for the last temperature
has elapsed, the test will terminate
unless a slope endpoint has been turned
On� If Temperature 2 is set, then at the
end of Time 1, the analyzer will ramp to
Temperature 2�
To set or change Time 1 or 2:
§ Press the Time 1 or Time 2 soft key to
display the Time 1 or Time 2 screen�
§ Use the numeric keys type in the desired
temperature, then press the Enter key�
The display will return to the Tempera-
ture 1 or 2 screen�
Slope
The slope function provides an auto-
matic endpoint for the test� The slope
function consists of two variables:
window of time and percent of initial
weight (%IW) change� During the test,
the weight change of the sample is
continuously monitored within a mov-
ing window of time� When the loss of
weight within the window is less than
the initial weight percentage set, the
slope criteria has been met� The final
weight is taken and calculation is
performed to end the test� This slope
is referred to as “actual slope” because
the endpoint is actually achieved�
