Calculated Industries 3302 - Manual (Page 7)

8VHU·V *XLGH ³ 
“none” or “Error” is displayed, depending on the
measurement situation. The unit will also display
“Error” if you make an incorrect entry, try to per-
form invalid dimensional calculations (i.e., adding
areas and volumes together) or the resulting answer
is beyond the range of the calculator. “Error” will
also appear if you enter a mathematical impossibil-
ity, such as division by zero.
There is no need to clear the “none” or “Error”
message. The next valid measurement or keystroke
automatically clears the display. The “none” or
“Error” message will not clear previously stored
values from memory.
