3.3 Transient Protection
Campbell Scientific recommends transient surge protection for sensors installed
in lightning prone areas. No lightning protection is capable of withstanding a
direct hit, but surge protectors afford a degree of protection for near misses.
Surge protection can be provided by Campbell Scientific’s SVP48 Surge
Voltage Protector. When an electrical surge occurs, the surge protectors
involved may need to be replaced.
3.4 Temperature Fluctuations
Temperature fluctuations can be minimized by using a minimum cable burial
depth of six inches and a sensor submersion depth of one foot.

3.7 BDR301
The CS400/CS405 can be connected to the BDR301 by using a DES-2
Desiccant Box and replacing the DES-2's standard five-lead cable with a six-
lead cable terminated with a ten-pin military connector. Figure 3-1 shows the
DES-2 wiring format with placement of a #7977 resistor.
