RAWS-F Remote Automated Weather Station for Fire Weather
5.5.3 Maintenance
There are no user-serviceable parts on the CR1000KD. No maintenance is
required.
5.5.4 Calibration
No calibration is required.
5.5.5 Troubleshooting
If a problem is suspected, the CR1000KD may be checked by connecting the
CR1000KD to the CR1000 PC board 9-Pin “CS I/O” connector using our 9-pin
serial cable (pn 10873). The CR1000KD display should be visible. Check the
CH100’s ON-OFF switch. If the display is not visible, check the CR1000
wiring panel for 12 volt power. If the CR1000 is unresponsive to CR1000KD
key strokes, there might be a problem with the CR1000 datalogger. Obtain an
RMA number before returning this equipment to Campbell Scientific for
repair.
5.6 CR1000 Datalogger
5.6.1 General Description
The CR1000 shown in FIGURE 5-4 provides sensor measurement,
timekeeping, data reduction, data/program storage, and control functions. The
CR1000 includes 4 MB of memory for data and program storage. A lithium
battery backs up the RAM and real-time clock. The CR1000 also suspends
execution when primary power drops below 9.6 V, reducing the possibility of
inaccurate measurements.
