2. Cautionary Statements

• The TE525-series tipping bucket rain gages are precision instruments.

Please handle them with care.

• Care should be taken when opening the package not to damage or cut the

cable jacket.

• Sensor is factory calibrated and should not require field calibration. Refer

to Section 9, Maintenance, for field calibration check and factory

• Debris filters, funnel, and bucket reservoirs should be kept clean.

• The black outer jacket of the cable is Santoprene


rubber. This compound

was chosen for its resistance to temperature extremes, moisture, and UV
degradation. However, this jacket will support combustion in air. It is
rated as slow burning when tested according to U.L. 94 H.B. and will pass
FMVSS302. Local fire codes may preclude its use inside buildings.
