Make sure the battery contacts are clean. I just fixed mine, as it had been sitting for some years and the batteries went bad.

I gently cleaned any "green mold" from the contacts with a light Scotch-Brite pad and some electrical contact spray that I got at a local hardware store.

I tested the batteries with my digital meter to make sure they were 1.5V or more and put everything back together. Works great!

Mean= average =(sum of data values)/(number of data values) Mode is the most frequent data value. Median: Sort the data in ascending order. The element in the middle is the median.

Press = to display the number. Th e EE key is a shortcut for *10^
