10.2 Entering Your Own Formula
10.2.1 F200 Entering Formula
To enter your own cover equation or one that may
have been recommended by a third party such as
your consultant, DairyNZ or Meat & Wool please do
the following:
- While the F200 is switched on, hold down the
‘Formula’ button. The display looks like this ‘F_ _
d’.
- Press the formula button again briefly then
change the ‘d’ (default) to ‘c’ (custom).
- Now press ‘Reset’ briefly and the display will look
like this: ‘0_ _ _’. This is the first of two numbers
you will enter. The first number is the equation
‘add’ number and the second the ‘multiply’
number. For example in the October equation
above, the first number (115) is the ‘multiply’
number and the second (850) is the ‘add’
number.
- The ‘add’ number is 4 digits long and can range
from 0 to 9999. Starting with the first digit,
press the ‘Formula’ button to change this digit
to a value from 0 to 9. Press the ‘reset’ button
when it is correct. NB: 850 for example would be
entered as (0850). The next digit will change to
a zero. Repeat this process until all 4 digits have
been entered. The display then changes to the
‘multiply’ number.
- The ‘multiply’ number has 3 digits and can range
from 0 to 199. The first digit will appear as ‘0’
Press the Formula button to change this digit to
a value of ‘0’ or ‘1’. Press the Reset button when it
is correct and the next digit will appear. The last
two digits can have values from ‘0’ to ‘9’. Repeat
this process until all digits are entered and the
display returns to its normal state.
