Using Modems with Sound Level Meters
2260 Semi-permanent Monitoring Kit
A sound level meter for monitoring in the field needs protection against
weather and tampering, and it needs a power supply other than its
internal batteries. Also, you need space and power for the modem.
For the Investigator Sound Level Analyzer Type 2260, the 2260 Semi-
permanent Monitoring Kit is available. It includes a weatherproof case,
12V battery, battery charger, cables, Outdoor Microphone Kit and soft-
ware for Type 2260 and for the PC. The case has room for all the
equipment including a modem, and it has a cable entry for feeding
external power to the system. A complete system including the 2260 is
also available: the 2260 Semi-permanent Monitoring System has all the
equipment in the Kit, plus the 2260, a calibrator, a tripod and an inter-
face cable for a PC. For ordering information, see the “Noise Monitoring”
System Summary sheet (BU3063).
