SS100 Sensor Simulator
1. General
The SS100 is a device used when the Campbell Scientific CR1000/LoggerNet
Training Course is taught out-of-house. The SS100 is powered by a nominal
12VDC power source, typically the datalogger itself, and provides several
outputs typical of those from sensors commonly measured by Campbell
Scientific dataloggers.
The Training Course instructors may use the SS100 in a variety of simulations
of their own choosing or use the analogies in this manual.
