5. Data Logging
The instrument continuously outputs a line of
data every second. A 'Wizard Upload Lead'
(Pt No. S/CB/327-1-030) is required, and
suitable data capture software must be
installed on your PC. This software is not
provided by RDS.
Each time you press the
CAL
button, the
instrument transmits a header line and the
'Sample ID' (line count) is reset to zero.
5.1

Connect the 'Wizard Upload Lead' to the 4-
way header 'PL1' in the 'Terminator' junction

RS232 serial port on a PC or laptop
computer.
If a serial port is not available, a Serial-to-USB
converter can be used (available from any
computer store).
