A text document can be set up as follows:

Open Windows Explorer and open the directory in which you wish the text document to be created. Select file, New and then new text document. Apply a new name to the text document. Close Explorer. In HyperTerminal, select the transfer menu and then capture text. A dialogue box will appear asking you where you wish to log the data. Select the text file you have just created. Select Start to begin capturing the data.

Apply power to the Model 740 (By plugging in data lead). To establish communications with the instrument, press the # key then the carriage return key continually. The # character will scroll down the screen as normal until the Ack (♠) sign appears. When this happens, communications will have been established. Follow the procedure as outlined below noting down all responses.


If you have an American keyboard, the # key is Shift 3. Note, the carriage return key is not the same as the Enter key on the number pad. It usually has this symbol on it ¿


Please type the following, where indicates the carriage return key:


#015                                               returns software version

#003                                               returns the serial number

#008 BOTH                                  Set the logging / output to BOTH

#028                                               Run the unit

After you have finished this procedure, select transfer, capture text and stop
