3.8 Data Processing and Data Analysis
3.8.1. Data Processing stage
a. Calculating Value kVp Average
results of testing by means of digital multimeter test tool do eksposi factors eksposi different and in each factor eksposi do eksposi 3 times.
From these results included statistical formulas to determine the mean value kVp:
Once in the know the mean of kVp then will test the actual output.
b. Finding Value Difference Voltage
At this stage of the processing of calculating the difference between kVp voltage is set on the control panel with kVp recorded output on the monitor screen digital multimeter test tool.
Finding the value of the voltage difference
c. Looking Presentations
Then the voltage difference in the change in the value of the percentage by the following formula, (Papp, 2006).
The difference voltage
% difference = voltage x 100%
Voltage Regulated
3.8.2 Data Analysis Phase
Results of the interpretation of the data is already in the later served in the form of tables and graphs to more easily take the conclusion. Then analyze the results the percentage value under the provisions of the tolerance limits according to Papp (2011) is ≤ 5%.
