In principle no factory calibration is needed. In the unlikely event that such calibration would be required, the

reader is referred to the corresponding Campbell Scientific Instruction Manual for the TE525 Tipping Bucket Rain

Gauge for further instructions.

3.1.5 Trouble Shooting

Problem 1: No rainfall is recorded in spite of clear evidence of a recent rain event.

Remedy 1.1: Check if all wires are properly connected, both to the rain gauge and to the CR10X wiring panel. The

reader is referred to table 1 in paragraph 2.2, and Annex 2 for the correct wiring of the CR10X. Check if the cable

from gage to logger has not been cut (for example during slashing).

Remedy 1.2: Check if the tipping mechanism in the rain gage is not blocked.

Remedy 1.3: Re-load METSTAT following the instructions given in paragraph 2.5.

3.2 Met One 034A-L Windset

3.2.1 General

The Met Station includes the Met One 034A-L integrated cup anemometer and wind vane for monitoring wind speed

and direction. Wind observations are mainly used for determining potential evaporation. However, these measure-

ments can also be useful for hydraulic design, selecting locations for wind mills, positioning air strips, etc..

Figure 8 shows the Met One 034A-L Wind Set.
