Re: [EnergyPlus_Support] Weather converter issues

No key -- you use conversion units.  (as designed -- no automatic try at conversion)

Field: DataConversionFactors

There should be as many DataConversionFactors entries as DataElement entries. These factors are multiplicative factors (i.e. the input value is multiplied by this factor) and can be used to process input data into the values used in the EPW weather files.

You need to supply the conversion factors.

I am trying to use the weather converter to format my site weather station data.  I find the help file lacking a concise list of conversion DataUnits.
Is there a key for barometric pressure in.Hg, wind speed miles per hour, wind direction compass points (N, NE, SSW), time in a 2:10 p format?
If not I can preprocess my file?
More importantly, it seems to choke on my 10 minute data file.  I set NumInHour=6, but I get following errors:
First read Hour number=0; Expected =1
First read Hour number will be used as hour=1 and reported if not same for each day read in
Warning ** Suspected missing data line after processing 1 days
Month=6 Day=9 Hour=1
Processing continues but may be in error
Warning ** DirectNormalRadiation    378.8 > max theoretical=   177.1 Wh/m² on date= 6/ 9 at hour= 5
These continue through the whole file processing, I only have global horizontal solar data for input reported as W/m², and this directnormal error seems to start at an hour crossing in the file after reading some sub hour data?Do I have to factor the input data for the shorter time step?
