7.2. Understanding Configuration Parameters
Mode (Default Setting: m
0
– m/m
0
* 100% )
Three formulas are available for performing moisture analysis:
1. W [%] = m
0
– m/m
0
* 100%, where moisture is determined in relation to initial weight
2. W [%] = m
– m/m * 100%, where moisture is determined in relation to current weight
3. W [%] = m/m
0
* 100%, where current weight is determined as a percentage of sample weight
Where: m
0
= initial (wet) weight, m = current weight, and W [%] = moisture as a %
Drying Temperature:
This parameter is used to define the maximum drying temperature for a sample.
Once the temperature is defined, it will be held constant for the duration of the drying time.
Sample Quantity:
In the Short Mode this parameter is used in conjunction with the Sampling Interval
parameter to have the analysis terminated when the successive weight measurements (samples) do not differ by
more than 2mg. When setting this parameter, the Analyzer will begin to take the set number of samples
(sample quantity) and compare the weight result of each. When the weight of the samples does not differ by
more than 2mg, the analysis will stop. This configuration method is particularly helpful when an adequate
Drying Time of the sample is uncertain. If the change between samples is less than 2mg, we can assume the
sample has been dried and the analysis can be stopped.
Sampling Interval:
In the Short Mode this parameter is used in conjunction with the Sample Quantity
parameter. It defines the time interval between sampling. The maximum Sampling Interval is 180 seconds. This
parameter can also be also used in the Time Mode for monitoring the moisture loss as well as for statistical
functions such as the Drying Chart, or to print and record the sample weights. (See Chapter 10. STAT
Configuration).
Rule of Thumb for the Short Mode: Higher number of samples and longer time intervals result in a more
accurate estimate for the total drying time of the sample, as well as the end result.
Drying Time:
This parameter is used to set the length of the drying in order to complete the analysis in the
Time Mode. When the Drying Time is reached, the analysis will stop.
