OPERATING THE MDC-360C 5-6
During a process, data is logged automatically up to 10 data point sets per minute.
At this rate the 27,000 data point storage can hold 45 minutes of data. To allow
for longer processes, the user has the ability to change the number of data point
sets stored per minute. The parameter to modify is called Data Points/Min and
can be found in the Utility Setup menu. The following table shows the total
storage time based on the number of data points per minute parameter.
Data Points/Minute Approx. Storage Time

Once a process has been selected, the screen will change to the rate vs. time graph
shown in Figure 5-10. The logged data will be plotted for the first layer of the
process. Plotting the data may take from 5 seconds for short layer to up to 15
seconds or more for long layers with a lot of data. Please note that while the data
is being plotted the controller will not read any key presses. When the data has
