There are two methods of making the Standard Reference Count. The
quickest is using the above procedure, which takes four minutes. The four
minutes counter indicates the amount of time remaining before the end of
the count. At the end of four minutes, the two count values are stored in the
DS and MS registers.
The second method is the statistical standard test. The gauge will take 16
one-minute counts and stored each 1-minute value. After 16 minutes, the
averages of the 16 counts are stored in the DS and MS registers. A statistical
test then would have been run on the 16 individual counts and an “R” value
displayed for both DS and MS. These values should fall between 0.5 and
1.5. If they are only slightly out, another test may be made but if the value is
greatly outside the 0.5 to 1.5 limits, service is needed. To run the statistical
standard test:
