There is also a Check Tilt function that may be enabled using a terminal program that solely outputs Tilt
Angle (X and Y planes, 0-89.9 degrees) and Z information (plus a compass heading on Wind Models) at 4Hz
if this level of accuracy is required. See para 6.8 for set up details.
If it is required to mount the unit at an angle e.g. 30 degrees then rotate the unit so that the unit north
marker points north and the X reading is +00 or -00 degrees. Whilst maintaining the X reading at 00
degrees, angle the unit so that the Y reading is +30 degrees for Northern Hemisphere Locations or -30
degrees for Southern Hemisphere Locations.
5.1.7 Rain
Tipping Bucket Rain Gauge (Kalyx supplied with GMX531 and can be used with
GMX550 and GMX551)
The Kalyx rain gauge tipping bucket mechanism is immobilised before shipping to prevent damage in
transit. To release the mechanism, remove the funnel from its base by unscrewing the three nylon
thumbscrews. Remove the piece of foam from under the bucket mechanism. This foam may be saved and
used whenever the rain gauge is moved.
The Kalyx mounting arrangement options are:
Baseplate Mounting
Due to the low weight of the rain gauge (1kg approximately) it must be mounted securely, the use
of the baseplate is recommended for this. However the gauge may be mounted via the three
holes in the base to a paving slab for example. It is suggested that rawlbolts are used for this
purpose as they provide a means of levelling the rain gauge.
1.
Unscrew and remove the 3 hex nuts and washers associated with the mounting plate.
2.
Lift off the tipping bucket base assembly to leave the metal baseplate and studs.
3.
Fix the baseplate to level ground using the 3 pegs provided through the 3 corner holes. The
baseplate may be mounted to hard surfaces like concrete by replacing the 3 supplied pegs with
screws and rawlplugs.
