For specifics regarding the operation and features of this unit, refer to the standard Model 81000 manual which follows
this addendum.
Campbell Scientific makes available an example datalogger program that is designed to work directly with the Model
81005A without the user having to develop a program. This program can be found on the Campbell Scientific Web site
shown below.
This program is offered at no charge as a Quickstart solution to the collection of data in a very short time. Given the
variety of applications, the program may have to be modified to meet specific customer requirements. Campbell
Scientific charges for custom datalogger programming with a one hour minimum and one hour resolution; please
