Count Range
24 Hour Tl Count Range
1 Hour Tl
Recommendation
0 to 9600 0 to 400 Insufficient Tl counts for CS725
SWE measurements.
9600 to 36000 400 to 1500 Useable Tl count range for CS725
SWE measurements. May
experience larger errors for higher
SWE values.
36000 to 48000 1500 to 2000 Good Tl count range for CS725
SWE measurements. Should
maintain specified operating
characteristics.
48000 or greater 2000 or greater Excellent Tl count range for the
CS725 SWE measurements.
9. Mounting
• If you are unable to determine that your structure or
mounting method is suitable for the CS725 sensor, please
contact an expert or professional who can assist you in
determining the structural mounting requirements for your
CS725 installation. CAUTION
• Always ensure that the collimator is secured to the
structure with the long safety cable.
• Always install the collimator after the main CS725 body is
mounted and secured to the structure.
The exact mounting height for the CS725 is not critical. However it is
recommended to mount the CS725 approximately 3.0 m (10 ft) above the
ground. If it is possible for snow levels to exceed 3.0 m (10 ft), then the CS725
should be mounted higher than the maximum snow height. If the CS725 is
submersed in the snow, it may be damaged by water ingress. The CS725 can
also be mounted lower than 3.0 m (10 ft); however, this will reduced the
effective area of coverage.
Once the CS725 is mounted, the actual installed height will need to be entered
into the appropriate setup parameter.
