3.1 Ships With
The TE525 ships with:
(1) Calibration sheet
(2) Hose clamps from original manufacturer
(1) ResourceDVD
(3) Screws from original manufacturer
4. Quickstart
Please review Section 7, Operation, for wiring, CRBasic programming, and
Edlog programming.
4.1 Siting
The rain gage should be mounted in a relatively level spot which is
representative of the surrounding area. The lip of the funnel should be
horizontal and at least 30 cm above the ground. It should be high enough to be
above the average snow depth. The ground surface around the rain gage
should be natural vegetation or gravel. It should not be paved.
The rain gage should be placed away from objects that obstruct the wind. The
distance should be 2 to 4 times the height of the obstruction.
• The pipe used to mount the bucket must be vertical. Use a torpedo level or
something similar to get it as vertical as possible.
• Take the funnel off of the top of the bucket and look inside towards the
bottom of the bucket — notice the bubble level. Center the bubble level
while mounting the bucket to the pipe. Replace the funnel and seat it
completely when the installation is complete.
4.2 Mounting
The CM300-series mounting poles provide a stainless steel 1.5 IPS vertical
pole for mounting the TE525 rain gage. Pole length is 58 cm (23 in), 119 cm
(47 in), and 142 cm (53 in) for the CM300, CM305, and CM310 models
respectively. The CM300-series offers pedestal base options as well, as shown
in FIGURE 4-2.
Use the enclosed hose clamps to mount the gage as shown in FIGURE 4-1.
The lip of the gage should be at least 5 cm (2 in) above the post or pole. Level
the rain gage after mounting it.
Before final leveling, press either end of the bucket down against
its stop to make sure the bucket is NOT hung up in the center. NOTE
