4.7 Certification CE (EU) The equipment meets the essential requirements of EMC Directive 2014/30/EU. FCC (US) FCC Part 15, Class "B" Limits This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. -
Page 10: Product Description
5 Product description 5.1 Design and function The pyrheliometer is designed to measure the direct short-wave irradiance (radiant flux, W/m ) which results from the radiant flux from a solid angle of 5 degrees. As standard CHP1 comes fitted with 10 kΩ thermistor and Pt-100 and temperature sensors; so that the small temperature dependency of sensitivity can be corrected in post-processing using the supplied test data. -

The use of attenuator circuits to modify the calibration factor is not recommended because the temperature response will also be affected. A high input bias current at the readout equipment can produce several micro-Volts across the impedance of the instrument and cable. The zero offset can be verified by replacing the instrument impedance at the readout equipment input terminals with a resistor. - Page 14 7.2.2.1 Power connection The minimum power supply voltage for the instrument is 5 V DC. 5-volt-power can only be used with a short cable, maximum 10 m. To ensure reliable performance, a voltage of 12 V DC is recommended. For the output of the power supply, it is recommended to protect it with a fast blowing fuse of maximum 250 mA rating. 7.2.2.2 Power consumption Typical power consumption SHP1-V for maximum output (1 V) Voltage (V DC)
- Page 15 7.2.2.4 Analog current output The SHP1-A (current version) is factory set to 0 to 1600 W/m for 4 to 20 mA. Negative inputs will make the output go below 4 mA. The irradiance value (E ) for the default setting can be calculated as shown below: solar ↓...

Page 16: Grounding Instrument
7.2.3 Grounding instrument Lightning can induce high voltages in the shield but these will be led off at the instrument or readout equipment. The shield of the cable is connected to the aluminum housing of the instrument through the plug body. 4 If there is no good ground connection at the instrument, connect the shield at the cable end to the ground at the readout equipment. -
