The HH2 is a hand-held portable data recorder from Delta-T Devices that can read and record data from the Profile Probe (PR1), ThetaProbe (ML1 and ML2), and Equitensiometer (EQ1 and EQ2).
The PR1 has 4 or 6 capacitance soil moisture sensors on a rod which can either be taken from site-to-site to record readings, or it can be left at a single site with a logger. The HH2 is only used if the is used in portable mode - if logging use SiteMenu/Import.
The readings will be left in an upload file with a name based on todays date with extension UPL. If the Delta-T programme HH2READ.EXE is used to upload the file will have the extension CSV.
A lookup file is needed to relate the HH2 identification to Probe for Windows site numbers. Three separate site identifiers can be entered into the HH2...
Datafile is not used by Prwin; Row is not used for PR1 data, but can be used for readings from individual ML2 or EQ1 units at the same site.
If a site is found in the upload file that is not in the lookup file a new line will be added with a site number = 9999. The lookup file should then be edited and the correct site numbers(s) entered, and the upload file re-processed.
The data from the PR1 should be in VSW% and does not need re-calibrating. However, by posting a serial number the data could be re-calibrated by Probe for Windows.
