digit.
2 Push [> >> >] again and again to move the cursor. Push [ ] or [ ] to change the value of the digit. If the digit is part of a
number, then make a selection from 0...9. If the digit is part of a custom unit name, then refer to the tables at the end
of this section for a list of the available characters. If the cursor is on the decimal point, you can change the position
of the decimal point.

INFORMATION!
If menu items have values that you can change, very large and very small values can be written
as a value with an exponent (b
n
). For example, if the value shown on the display is 100.00
+03
, this
value is equal to 100 × 10

or 100000.
Button Description Function
Right
•
Enter the menu item and see the value stored at this time.
•
Enter the menu item configuration level to change the value.
•
Move the cursor to the next digit on the right. If the cursor is on the
last digit, push [>>>>] again to go back to the first digit. You can also
put the cursor on the decimal point.
Enter Accept the value and go back to the sub-menu.
Esc (Escape) If you push these buttons immediately after you change a value, the
device also ignores this change and goes back to the menu.
Down If the cursor is on a number, this button decreases the digit value. If
the cursor is on the decimal point, this button moves the decimal
point to the left (this decreases the value by a factor of 10).
Up If the cursor is on a number, this button increases the digit value. If
the cursor is on the decimal point, this button moves the decimal
point to the right (this increases the value by a factor of 10).
