PLC5 Gas Connector
The PLC5 gas connector (white) has two small “O” rings (see below) to make a leak-tight seal with the
TARGAS-1 console. Periodically apply a slight smear of silicone grease on each “O” ring to keep it from
cracking or breaking.
PAR Sensor
The PAR Sensor should be recalibrated every two years. Please consult with PP Systems for PAR
sensor recalibration services. Calibration can also be performed by the end user if required. Refer to
PAR on page 110 for more information on recalibration of the external PAR sensor.
Light Unit
The light unit should not require recalibration. If you suspect any problems with your light unit please
contact PP Systems.
