RS232 SERIAL INTERFACE
The calibrator may send data logging information to an IBM PC or
compatible computer by connecting the unit and the PC via an RS232 cable,
and installing the "Calsoft" software. Contact your supplier for details.
Ensure that there is a connection made before the calibrator is
switched on.
The RS232 cable must be fitted to both the unit and the PC before either unit
is powered up, otherwise, data integrity cannot be guaranteed. Once the
cable is fitted, it does not matter which unit is powered up first.

RS232 cable and running Calsoft to accept or display data.
