SECTION 3. TROUBLESHOOTING
3-6
NOTE: If at any time you make a mistake
or loose you place, start over by keying the
* symbol.
The weather station should be left in the LOG12
mode to minimize current drain on the batteries.
NOTE: If the battery power is lost, the data
stored in the CR10's Final Memory IS
LOST.

Upon connecting the keyboard view locations 1
(CR10 Temperature) and 10 (Battery Voltage).
If the datalogger is not operating properly, the
CR10 Temperature will not record a reasonable
value. The battery voltage should read no less
than 11.76 volts. If either of these conditions
arise, check the power source to the
datalogger. Be sure that the charging light is lit
while the AC or Solar Panel is plugged into the
power supply. If this light is not lit, chances are
that the charging circuit is bad and will need to
be replaced. In this case the batteries will also
most likely be bad and will need to be replaced.
3.3.2 12 VOLT SUPPLY
The 12V battery supply should not be
discharged below 11.76 Volts. If this
occurs, the batteries will be damaged and
will need to be replaced. Check the 12V
supply with a volt meter. (Maintenance
guide)
3.3.3 5 VOLT SUPPLY
On the wiring panel of the CR10 there is a
terminal marked 5V. Check the 5V supply
with a volt meter, measuring between the
5V terminal and ground. This 5V supply
should be 5 0.1 volt. If not, there is a
problem with the CR10.
