5. Characterization

Has this particular instrument been characterized (determination of the deviations from ideal behaviour)?
yes no
If 'yes', answer the following questions, if 'no' continue with paragraph g) and give only an estimated uncertainty.
 
a) Area of aperture:

A= + / - mm2
Method of determination:
b) Cavity reflectance:

ER= + / -
Method of determination:
 
c) Difference in response between radiation and electrical heating (non-equivalence, e.g. different temperature distribution in the cavity, resistance of black coating, aperture heating, etc.):

EHE= + / -
Method of determination:
 
d) influence of diffraction and straylight in view limiting device:

EST= + / -
Method of determination:
 
e) Lead heating

ELE= + / -

POWER REQUIREMENTS AND DATA HANDLING

1. Power requirements


Wherever possible, please set all your equipment to accept the Swiss AC mains power (230 V, 50 Hz).

Upon request each measuring place can be supplied with the following additional power:

AC: 115 V, 50 Hz; 115V, 60Hz
DC: 6 V regulated and 2 V regulated

For planning the power distribution we need the following information:

Item Voltage [V(, Hz)] Power [W] Remarks
 
The workspace on the tables is 1 x 0.75 m2, with an elevated platform for the instruments. If you need more space, please justify and specify:

2. Data handling

Please specify here if you will manually read your irradiance values or connect your pyrheliometer to a computer with data acquisition software. For manually operated instruments a web interface will be provided to type in your readings, while automated data acquisition systems can upload the data files to our FTP server. The acceptable file and data format will be defined in due time.
I will use an automated data acquisition system obeying the file and data format.
manually read my irradiance values. Need a netbook from WRC.
 
TRANSPORTATION OF INSTRUMENTS

Please note: This form refers to all the instrumentation and equipment which you are going to bring to Davos! We will try to arrange for informal import clearance of all IPC-XII equipment.
I will hand carry my instruments through Swiss customs. I will enter Switzerland at .

 

I will send my instruments by air or surface freight according to the shipping instructions (to be distributed later).

The weight of the shipment is approximately kg
The size of the shipment is approximately m3
