Appendix A. Optional RGB1 Levelling
Baseplate
The RGB1 levelling baseplate is only supplied with the ARG100 raingauge when
specifically ordered. It is suitable for fast, semi-permanent installations on soft ground.
Install the RGB1 as follows:
1.
Take the funnel assembly off the raingauge.
2.
Drill out the three holes in the raingauge base to 6.5mm diameter and debur.
3.
Screw one 6mm full nut on each stud and screw the studs into the baseplate flush
with the bottom surface. Tighten the nut up to the baseplate to lock the studs in
position.
4.
Screw on the lower plastic thumb nuts and slide the raingauge over the studs until
it is sitting on top of the thumb nuts.
5.
Complete the assembly as shown below for each stud.
6.
Fix the baseplate to the ground using the four pegs provided through the four
outer holes. If force is needed, remove the raingauge first, fit the base, and then
replace the raingauge.
7.
Adjust the thumb nuts to level the gauge. Ensure that the thumb nuts are tightened
to secure the gauge.
8.
Replace the funnel and check operation of the gauge.
