4.3 Entry of numerals, letters and characters
Numerals, letters, punctuation marks and special characters are
entered on the alphanumeric keypad on the meter or an external key-
board.
Entering characters is required in operating situations such as the fol-
lowing:
z Entry of the date and time
z Entry of an ID, e. g. if you want to store measurement data
z Entry of the user name and password
z User management
Character set The following characters are available:
z Numerals 0 ... 9
z Letters A ... Z
z Punctuation marks . -
Operating principle Characters can be entered as long as an input field is displayed.
The keys of the alphanumeric are assigned to the characters that are
printed on them. Example: With the <PQRS 7> key you can enter the
following characters: 7, P, Q, R, S.
The required character is selected by pressing the key several times
(similar to a cell phone). The numeral appears on the first pressing if
the key is assigned to several characters. One keypressing is sufficient
to enter a numeral.
The key for punctuation marks (<- .>) is assigned to a decimal point of
minus sign, depending on the context. If a number is in front of the
punctuation mark, a decimal point is automatically displayed, in all
other cases a minus (-).
A character is taken over in the input field if
z the character is highlighted longer than one second,
z the character is confirmed with <OK>,
z another alphanumeric key is pressed.
Operating example:
