Data Recorder
Memory
Data stored into 4 independent memory areas.
104K battery backed RAM -stores a total of 29,000
data readings(plus time & date stamp records ).
System Indicator
•1 Second flash-Communicating with computer
•2 Second flash -Normal (logging mode)
•4 Second flash -Sensor out of range, program fault or flat battery
Battery
6 volt 3.0AH internal sealed rechargeable gel cell -
capacity for 6 weeks’ operation without sunlight.
