Printing
1. When a reading has been taken in the MEASURE mode, the
concentration/raw fluorescence result is displayed on screen. This can be
printed to a serial printer or PC if attached via the RS232. The fluorimeter is
designed for use with the optional accessories of the Porti printer (P/N 037-
701) or DataWay PC software (P/N 050-501).
Porti printer
1. Connect the Porti printer to the RS232 socket on the back panel of the
instrument using the supplied cable.
2. The printer can be used without connection to a mains power supply for
periods of time by means of the integral battery. If the battery is low or mains
power is preferred, plug in the power supply pack using the appropriate
cables, as provided with the printer.
3. Ensure the printer is fitted with a roll of thermal paper. Paper can be
advanced by use of the Feed button on the printer.
4. Switch on the printer with the black button and the left hand side LED will
light. The LED will be green when mains power is used or the battery is well
charged. If the LED shows flashes of red and no mains power supply is used,
this indicates the battery level is low. Further instructions on the Porti printer
can be found in the operator manual included with the printer.
5. Now to print the result displayed on the instrument screen just press the Print
button on the fluorimeter.
