Do not force the cell adapter out of the instrument as serious damage can
occur.
Connect to a printer or computer
Use the serial interface (RS232) connector on the back of the instrument
to transmit data from the instrument to a printer or a serial
communication port on a computer. Refer to
Figure 2 on page 8.
To connect a serial printer to the instrument, use a printer cable
assembly that is terminated with a standard 25-pin D connector. A serial-
to-parallel converter can be used to print to a parallel printer. Data is
transmitted to a printer as a 39-character string plus the line feed and
carriage return.
To connect a computer to the instrument, use a serial communication
cable with a DB9 connector.
Note: Use of the specified cable or equivalent is mandatory for CE compliance (a
shielded cable assembly must be used).
