1.1 Product overview
According to International Standard ISO 9060:1990 and the World Meteorological Organization (WMO) a pyrheliometer is the
designated type of instrument for the measurement of direct solar radiation. The SHP1 pyrheliometer is compliant with the
“First Class” class specified by the international standards.
This manual, together with the instruction sheet, provides information related to the installation, maintenance, calibration,
product specifications and applications of the SHP1 pyrheliometer.
If any questions should remain, please contact your local Kipp & Zonen representative or e-mail the Kipp & Zonen customer and
product support department at: support@kippzonen.com
Please go to www.kippzonen.com for information about other Kipp & Zonen products, or to check for any updates to this manual
or software.
1.1.1 The SHP1 pyrheliometer
SHP1 pyrheliometer is a high quality radiometer designed for measuring direct short-wave irradiance (radiant flux, W/m²) which
results from the radiant flux from a solid angle of 5 degrees.
SHP1 pyrheliometer features internal digital signal processing and interfaces optimised for industrial data acquisition and control
systems. Kipp & Zonen has developed a smart interface that features RS-485 Modbus® data communication for connection to
programmable logic controllers (PLC’s), inverters, digital control equipment and the latest generation of data loggers. Amplified
Voltage or Current outputs are also included for devices that have high-level analogue inputs or current loop interfaces.
The SHP1 is available in two versions. The SHP1-V has an analogue voltage output of 0 to 1 V, the SHP1-A has an analogue current
output of 4 to 20 mA. Both have a 2-wire RS-485 interface with Modbus® (RTU) protocol. Both versions have minimised power
consumption and are protected against short circuit and reversed polarity. The digital signal processing provides faster response
times and, with an integrated temperature sensor, individual corrections for the temperature dependence of the detector are made.
To achieve the required spectral characteristics SHP1 uses a quartz window and thermopile detector. The waterproof connectors
have gold-plated contacts.
The pyrheliometer is normally delivered with a waterproof plug pre-wired to a high quality signal cable, typically this is 10 m
long but other lengths are available. The instruments can also be ordered with a plug only, for the user to fit their own cable.
.
1.1.2 International Standard
For the SHP1 Second Class pyrheliometer ISO standard ISO 9060 applies.
Fully compliant with all ISO 9060:1990 specification criteria for an ISO Second Class pyrheliometer, the SHP1 features a
thermocouple sensing element. An integrated temperature sensor with active and individual measured temperature compensation
is included for improved temperature dependence of sensitivity.

.
Please follow the instructions in this section carefully for the mechanical and electrical installation of the SHP1 pyrheliometer.
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
Check the contents of the shipment for completeness (see below) and note whether any damage has occurred during transport. If
there is damage, a claim should be filed with the carrier immediately. In the case of damage and/or the contents are incomplete,
contact your local Kipp & Zonen representative or e-mail the Kipp & Zonen customer and product support department at:
support@kippzonen.com
Although a SHP1 pyheliometer is weather-proof and suitable for use in harsh environmental conditions, it has 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 a SHP1 pyrheliometer:
Smart pyrheliometer and rain shield

2.2 Tools required
The tool required to mount a SHP1 on a SOLYS 2 or 2AP sun tracker is a 3 mm Allen key. Normally, the drying cartridge for the
SHP1 should be hand-tight, but a 16 mm or 5/8” open-ended wrench / spanner can be used to loosen it.
Check the condition of the desiccant in the SHP1 and replace before installation, if necessary; for example after a long storage
period.
The SHP1 instruction sheet plus the sun tracker manual contain all information to do the installation. When using the digital
output it might be convenient to set the Modbus® address prior to visiting the site, otherwise a computer and RS-485 / USB
converter may be required during installation.
2.3 Location and support
The following steps must be carefully taken for optimal performance of the instrument.
2.3.1 Location
Ideally, the site for the pyrheliometer plus sun tracker should be free from any obstructions to the hemispherical view from the
plane of t
