USING APOGEE QUANTUM SENSORS WITH ZENTRA SYSTEM

2.1 SET UP MOUNTING ASSEMBLY

Apogee Quantum sensors must be level to accurately measure PPFD incident on a horizontal

surface. Each Apogee Quantum sensor purchased from METER comes with an AL-120 Solar

Mounting Bracket with Leveling Plate. The AL-120 can be mounted to either a horizontal or

vertical post, depending on which set of holes is used.

Align the cable M8 connector with the sensor M8 connector and seat connectors fully.

Tighten the cable screw to maximum hand-tight (Figure 1).

M8 connectors are easy to overtighten. Do not use pliers or other tools to tighten

this connector.

Mount the sensor to the leveling plate (Figure 2) with the included nylon screw.

Leveling plate

Attach the leveling plate to the mounting bracket using the three machine screws

included.

Attach the mounting bracket either to a horizontal arm (Figure 2) or vertical post using

the included U-bolt.
