5.9.4 Copy Curve Temperature curves can be copied from one location inside the Model 336 to another.
This is a good way to make small changes to an existing curve. Curve copy may also be
necessary if you need the same curve with two different temperature limits or if you
need to extend the range of a standard curve. The curve that is copied from is always
preserved.
The copy routine allows you to overwrite an existing user curve. Please ensure the curve
number you are writing to is correct before proceeding with the copy curve operation.
1. To perform the Copy Curve operation press Curve Entry , scroll to Copy Curve, then
press Enter .
2. Scroll to the desired curve to copy, and press Enter . A list of user curves is dis-
played.
3. Scroll to the desired user curve location to copy to, and press Enter .
4. Choose Yes at the confirmation message to finalize the operation.
5. To cancel the operation, either choose No to the confirmation message, or press
Escape .
