If sending the CR300 to Campbell Scientific for calibration or repair, consult
first with Campbell Scientific. If the CR300 is malfunctioning, be prepared to
perform some troubleshooting procedures. Many problems can be resolved
with a telephone conversation. If calibration or repair is needed, the procedure
shown in the Assistance page at the beginning of this manual should be
followed when sending the product.
8.1 Calibration
Maintain a level of calibration appropriate to the application. Campbell
Scientific recommends factory recalibration of the CR300 every three years.
Consider the following factors when setting a calibration schedule:
• the importance of the measurements
• how long the datalogger will be used
•
the operating environment
•
how the datalogger will be handled
8.2 Sending an Operating System
Campbell Scientific posts operating system (OS) updates at
www.campbellsci.com/downloads when they become available. Before
deploying instruments, check operating system versions and update as needed.
The CR300 operating system version is shown in the Status table, Station
Status Summary , and Device Configuration Utility Deployment |
Datalogger . An operating system may be sent through Device Configuration
Utility
or through program-send procedures.
Sending an operating system through Device Configuration Utility resets all
settings on the datalogger to factory defaults and clears its memory. To send an
OS through Device Configuration Utility , follow the procedure on the Send OS
tab.
Watch the video:

.
In most instances, sending an operating system as a program preserves settings.
This allows for sending an operating system remotely; however, this should be
done with great caution as updating the OS may reset the CR300 settings, even
settings critical to supporting the telecommunication link. To send an OS this
way, use the Send New button in the datalogger support software, as shown in
Section 4.5 , Send a Program
(p. 14)
.

Note the following precautions when sending as a program:
•
Because sending an OS resets CR300 memory, data loss will certainly
occur. Depending on several factors, the CR300 may also become
incapacitated for a time.
•
While the programs are retained in memory, no program will be set to
run after the operating system is sent. To overcome this, create a
“default.CR300” program and store it on the CR300. Default.cr300
