Install a cell adapter
Note: Use the application specific calibration (ASC) ability of the instrument to
provide direct reading of results with cell adapters installed. If the ASC ability is not
used, a new calibration curve must be developed each time a cell adapter is used.
1. Align the tab on the cell adapter toward the front of the instrument
(Figure 9).
2. Put the cell adapter in the sample cell holder.
3. Calibrate the instrument each time the sample cell diameter is
changed. Calibrate using sample cells of the same path length as the
sample cell that will be used to measure samples.
Note: If test tubes are taller than the cover for the sample cell compartment,
use the tall light shield provided with the cell adapter.

Remove a cell adapter
1. Carefully pull the cell adapter up until it is half out of the sample cell
holder.
2. Slowly turn the cell adapter 90 degrees counter-clockwise.
3. Pull the cell adapter up to remove it.
N O T I C E
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 an external 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).
Configure the printer output
1. Push SETUP. The SETUP light turns on.
2. Use the arrow keys to select the printer option:
Option Description
01 Sets the printer speed—FAST PRT or SLOW PRT (2.5 second
delay).
02 Sets the printer to use—INTERNAL, EXTERNAL
(RS232 connection) or BOTH.
03 Sets the print time interval for automatic prints of the reading on the
display in minutes and seconds (mm-ss)—00-15 to
99-99 (disable=00-00).
Note: To turn the print interval feature on or off, push PRINT.
04 Sets the printer contrast—0 (darkest print) to 7 (lightest print).
3. Push ENTER.
4. Use the arrow keys to change the value.
