4.5 Decimal point (Display only)
The decimal point indicates the
number of decimal places.
0
0.0
0.00
0.000 three decimal places
4.6 Set mode
manual set (red key) and
electrical set
no set
(red key and set input
locked)
electrical set only
manual set only
4.7 Set value (Allows user to preset start number)
521K.2 (Opto output
activates at"0"or less.
Can be used as
subtracting preset counter)
Use 2 keys to set value
-199999... 999999
(number of decimal places
depends on the decimal
point option)
4.8 End of programming
Programming routine will
be passed through once
again. All parameters can
be checked.
Programming routine will
be left and the new
parameters will be stored.
Afterwards the device is
ready to use.
