Addendum to HH2 User Manual Version 4.0 for ML3
This option helps you to install the ML3 linearisation table into the HH2
meter using the HH2Read PC software.
It is not that difficult (see the link below for instructions).
The downside is - each time your HH2 battery goes flat for more than 30
seconds you will have to reinstall the ML3 linearisation table.
For details see the document Support for the ML3 Soil Moisture Sensor
with an HH2, available on our website and on the Delta-t Software and
Manuals DVD
3) No upgrade: It is possible use an ML3 with earlier versions of the HH2
meter. It takes some effort. You need to create a linearization table called
ML3.lin in the correct format and load it into the HH2 using HH2Read.
The disadvantages are is the same as item 2 above, plus you also have to
remember to select the Device PR1 Special. (which is provided as a place
holder for additional tables).
