The instrument is available with an optional RS 232 communications interface (see ordering information).
The version with the interface offers the following advantages over the standard configuration:
■
The titration results are automatically transmitted to the PC by double-clicking on the CLEAR key.
This eliminates transcription errors while recording primary data, and complies with an important
requirement of GLP.
■ With each data transfer, the burette sends the titrated volume, the serial number of the instrument, the
nominal volume and the adjustment value, as well as the next scheduled calibration date. Thus, all raw
data is collected.
The transmitted data is recognized as keyboard inputs by the PC. This universal input format ensures that
the instrument is compatible with all PC applications that accept keyboard inputs.
To connect the instrument to a USB interface, simply use a standard USB/RS 232 adapter.
Items supplied include a connection cable (9-pole Sub-D connector assembly) and a CD* (driver software
and a public RS 232 communication protocol). All information required for integration into an existing da-
tabase is available to programmers. In addition, the CD also contains a sample application in XLS format
as well as an instruction manual and the testing procedure.
