Besides the time, the LCD display also shows a cursor
beneath the digits. The CURSOR < and CU RSOR
> keys in the SETUP field can be used to move the
cursor. The SETUP +/—keys change the programmed
time.
The printer's realtime clock may be programmed
be accurate to the second. To do so, preset the clock
to a time slightly ahead of the current time (e.g. one
minute ahead). Wait until the set time is reached,
then immediately press one of the MODE buttons to
exit this function and start
10: SET DATE
For setting the current date in the format DD-MM (day
- month).
Besides the date, the LCD display also shows a cursor
_ beneath the digits. The CURSOR < and CURSOR
> keys in the SETUP field can be used to move the
cursor. The SETUP +/- keys change the programmed
date.
Illegal values, e.g. 32 07, are rejected and an audible
and visible warning signal is given.
11: SET YEAR
For setting the current year in the format 19xx.
Besides the year, the LCD display also shows a cursor
" _ ") beneath the digits. The CURSOR < and CURSOR
> keys in the SETUP field can be used to move the
cursor. The SETUP +/—keys change the programmed
year.
The year will be automatically advanced to 2000 when
the time comes.

to the unzoomed scope screen image. The zoom range
can be separately set for each channel.
Example: the setting CHI 0-0, CH2 3-6 will cause the
signal from Channel 1 depicted in the division at the far
left of the screen graticule to be printed in expanded
(magnified) form over the entire width of the printout
(10 divisions). At the same time, division 3, 4, 5 and 6
are also magnified and printed over 10 divisions. The
