HOW TO SET THE VALUES
With WM30 the values setting is even more simple, it is possible to increase or decrease every single digit,
it is possible to easily obtain the wished value or change directly from one multiplier to another one.
Example: use of the menu relevant to the current ratio.
01
During the programming phase the instrument provides useful information:
a
recognition of the programming mode;
b
identifier number of the menu (see also the programming flow chart);
c
edit, identification of the line subject to set;
d
cursor that identifies the digit subject to set;
e
maximum and minimum limit of selectable variable.
02
Use the keys
the cursor to match the wished digit using the key 4, every key press corresponds to a left shifting of the

When the last digit on the left is matched by the cursor
change the decimal point and the multiplier

To modify the decimal point position and the multiplier use the keys 6 to have the wished value.
