7.3.1 Installation in a 41003-5 10-Plate Shield
1. The HC2S3 is shipped with an adapter to work with the 41003-5 10-plate
shield. Loosely thread the collar adapter into the base of the 10-plate
shield.
2. Insert the HC2S3 sensor into the collar. Leave about 2.5 cm (1 in) of the
sensor exposed below the collar. See FIGURE 7-1 .
3. Hold the collar and sensor, and finish threading the collar into the shield
by hand. Tighten the collar around the probe until it firmly grips the body
of the probe. Use an adjustable wrench if necessary, but do not overtighten
the collar.
7.3.2 Installation in a RAD10 10-Plate Shield
1. Loosen the nut on the entry gland at the bottom of the shield.
2. Insert the sensor up into the gland. Leave about 2.5 cm (1 in) of the sensor
exposed below the nut. See FIGURE 7-2 .
3. Using an adjustable wrench, tighten the nut on the gland until the sensor is
held firmly in place. Do not overtighten.
7.3.3 Mount the Shield
1. Attach the radiation shield to the tripod mast, crossarm, or tower leg using
the supplied U-bolt. See FIGURE 7-1 and FIGURE 7-2 for examples of
shield mounting.
2. Route the cable to the datalogger, and secure the cable to the mounting
structure using cable ties.
