2. In the Math Entry Menu, use the NEXT ROW and PREV ROW
keys to scroll to the appropriate row. Then use the arrow key to
reach the desired symbol.
3. Once the key is on the symbol, press [YES] to enter the symbol
into the equation. Use the number keys to enter numeric values.
(Press [NO] to remove any mistaken or unwanted symbols or
numbers.)
4. To enter a particular measured parameter into the equation, click
on the MODE symbol at the right of the third row. A list of
parameters will appear. Scroll through the list until you reach the
desired parameter, and press [YES].
5. A list of units will then appear. Scroll through the list with the
arrow keys until you reach the desired units, and press [YES].
Note:
If you wish to link a parameter from a particular channel, add
“(Ch#)” after you select the parameter. For example, “DP/
°C(2)” is the dewpoint in °C on channel 2.
6. Press the DONE key to confirm the equation. The meter will
return to the User Function Menu. However, if the user function
contains an error (for example, unbalanced parentheses or a
missing operator), the function will be labeled “INVALID.”
7. Press DONE to return to the Option Menu, or repeat the procedure
to enter functions for other channels or pages.
