Fig. 16— (Left) The circuit board inside the Biofl uorometer holds up to seven LED modules
and has two photomultipliers.
Fig. 17— (Right) Each LED module is secured to the circuit board by two screws located on
either side of it.
3. To remove an LED module:
Disconnect the BNC terminated end of the fi ber optic cable that comes out of
the back end of the LED module.
Loosen the two screws on the sides of the LED module (Fig. 17).
Lift the LED module off the circuit board, being careful not to bend the fi ber
optic cable.
4. To install an LED module:
Align the serial connection on the bottom of the LED module with the
appropriate LED port on the circuit board.
Press the LED module into place and secure it by tightening the two screws on
the sides of the LED module.
Connect the BNC-terminated end of the fi ber optic cable to the proper emission
port.
