Model 336 Temperature Controller
To store the curve to a user curve location in the Model 336: click Write to Instru-
ment. The Write Curve to Instrument dialog box appears. Select a user curve location
to write the loaded temperature curve to, and click OK .
To write the currently loaded curve to a file: click Write to File . A Save Browser dialog
box appears. First use the Files of Type drop-down box to select the file format in
which to save the curve. Then choose a directory and a file name, and click
Save .
The .340 file format is an ASCII text file which can be read and altered using a stan-
dard ASCII text editor. Care must be taken when altering the .340 text files to ensure
that all of the values are stored in the same position in the file as the original values,
using the same number of digits. To alter curve files, it is recommended to use the .XLS
file format, which can be altered using Microsoft Excel®. If using formulas to alter
curves, you must copy the results of the formulas and paste them back into the origi-
nal cells of the breakpoint values. The Embedded Curve Handler™ cannot interpret
formulas in cells. In most versions of Excel®, this can be done by copying the formula
results, then pasting them in the appropriate cells using the
Paste Special command,
and selecting Paste Values . Refer to the appropriate Microsoft Excel® documentation
for details on the Paste Special operation.
The Embedded Curve Handler™ cannot read files in the Microsoft Excel® ".XLSX" (Excel®
2007 or newer) format. When saving files from Excel®, be sure to save them in the ".XLS"
(Excel® 97 - 2003) format so that the file can be read using the
Embedded Curve Handler™ utility.
