2.2 Installation
2.2.1 Bench System Test
Prior to physically mounting the MetPak RG in its final location, we strongly
recommend that a bench system test is carried out to confirm the system is
configured correctly, is fully functional and electrically compatible with the selected
host system and cabling (preferably utilising the final cable length). The required
data format, units, output rate, and other options should also all be set up at this
stage.
Note that MetPak RG is supplied with a matching Rain Gauge and its tip calibration
factors will have been pre-programmed into the MetPak hub box. If a replacement
Rain gauge is used then the Hub box will need re-programming using Gill MetSet
Software with the new tip calibration factor (if this has changed).
2.2.2 Bench Test Equipment Required
