Please follow the instructions in this section carefully for the mechanical and electrical installation of the SGR series pyrgeometers.
Do not turn on power to the instrument until instructed to do so.
Note
Do not connect the instrument to a computer until instructed to do so.
Note
Do not turn on power to the operating computer until instructed to do so.
2.1 Included with the product

Although all SGR radiometers are weatherproof and suitable for harsh environmental conditions, they have some delicate
mechanical parts. Please keep the original packaging for safe transport of the radiometer to the measurement site or for use
when returning the radiometer for calibration.
The following items are included with SGR series pyrgeometers:
1. Radiometer
2. Sun shield
3. Optional cable, pre-wired with 8-pins connector or connector only for customer cable
4. Test reports
5. Instruction sheet
6. Radiometer fixing kit
The calibration certificate supplied with the instrument is valid for 1 year from the date of first use by the customer, subject to the
variations in performance due to specific operating conditions that are given in the instrument specifications. The calibration
certificate is dated relative to the time of manufacture, or recalibration, but the instrument does not undergo any sensitivity
changes when kept in the original packing and not exposed to light. From the moment the instrument is taken from its packaging
and exposed to irradiance the sensitivity will deviate slightly with time. See the 'non-stability' performance (maximum sensitivity
change per year) given in the radiometer specification list.
2.2 Mechanical installation
The mechanical installation of the radiometer depends upon the measuring purpose. Different measuring methods will be
explained in the next paragraphs.
2.2.1 Installation for measurement of long-wave downward radiation
The following steps must be carefully taken for optimal performance of the instrument. The tools required to fit an SGR series
pyrgeometer to a support are a 4 mm (M5 socket head screw) Allen key and a 8 mm (M5 nut) wrench / spanner.
