2. Setup

1. How do we set our own file names in YESDAS-2?

You can modify the names of data files YESDAS-2 produces in a Yesdas Manager channel profile, or manually via MS-Windows Explorer. However, we recommend that you stick with the default naming conventions that YESDAS Manager uses. If you do decide to modify file names after they are downloaded, do not change the .xmd file extension.

2. I do not have a UVPS-1 power supply or a YESDAS-2 data logger. How do I hook up a UVB-1 pyranometer to my existing data logger and DC dual output power supply?

Step 1. You need a source of +12Vdc at 1A and -12Vdc at 30 mA.

Step 2: You need something to record the analog output of the UVB-1. This output is proportional to the UV-B irradiance, and is calibrated at the factory. If you happen to have a Campbell CR-10 that only can do +/- 0-2.5v, you can use a resistive voltage divider to prescale the signal down. Of course, if you do not need a data logger, a simple handheld D.V.M. or chart recorder will also work.

If this all sounds a bit complicated, we sell a complete 32-channel data logger/ power supply system, YESDAS-2, as well as a simple UVPS power supply. Both the YESDAS-2 and UVPS-1 convert 110/220Vac to provide the +12 Vdc/-12Vdc voltages and are housed in weatherproof NEMA-4X enclosures. The YESDAS-2 supplies DC power from AC mains and logs data from up to 32 analog instruments and 6 pulse type digital instruments. YESDAS-2 is optimized for solar measurements and knows the sun's elevation angle. This is stored with each data reading and permits post angular correction of direct-normal radiometer data.
