Shown Digits: Key “Digits”
The key “Digits” allows to hide decimal places which will replaced by a underscore. Here the value is
rounded mathematically correct. The use of this function does not interfere with the precision of the
FM 3002 in any way. It is only a reading simplification.
Every key press hides one more decimal place up to maximal four places.
example with 1.2345678 T:
key press
display
0
1.2345678 T
1
1.234568_ T
2
1.23457__ T
3
1.2346___ T
4
1.235____ T
5
1.2345678 T
…
…
The using of the key “Digits” has a anomaly. To avoid misunderstandings only decimal places can be
blinded out. If there are not enough decimal places the error message “More decimal places needed” is
displayed.
Double-pressing results in the next possible selection. The same applies to the key “Unit”.
See also chapter 3 Serial Interface for hiding the decimal places.

Acoustic Feedback
Every new setting is acknowledged acoustically by a two-tone. At an error message the feedback is a
disharmonic tone.
