General Maintenance
•
An occasional cleaning of the glass on the
solar panel will improve its efficiency.
•
Check sensor leads and cables for
cracking, deterioration, proper routing, and
strain relief.
•
Check the tripod or tower for structural
damage, proper alignment, and for
level/plumb.
6 months
•
Clean the temperature/humidity sensor.
•
Clean the Gill Radiation Shield.
1 year
•
Replace anemometer bearings.
•
Calibrate the rain gage.
•
Calibrate the HMP45C/HMP35C probe.
•
Check calibration of CS500 RH Probe;
replace RH chip if necessary.
•
Check internal RH chip (MetData1 and
ET101/106 only). Replace if >5% off.
2 years
•
Calibrate the solar radiation sensors (some
users suggest yearly).
•
Calibrate the temperature sensor.
•
Replace the wind vane potentiometer and
bearings.
4 - 5 years
•
Replace sensor cables as required.
6.2 TROUBLESHOOTING
6.2.1 NO RESPONSE USING THE KEYPAD
Check keypad response after each of the
following steps.
A.
Make sure the battery has been installed,
and the power switch, if any, is "ON"
(Section 7).
B.
Use a voltmeter to measure the voltage on
the 12 V and G terminals; the voltage must
be between 9.6 and 16 VDC.
C. Disconnect any sensor or peripheral wires
connected to the 5 V and 12 V terminals.
D. Disconnect any communications or storage
peripherals from the datalogger.
E.
Reset the datalogger by turning the power
switch to "OFF", then to "ON" or
disconnecting and reconnecting the battery.
F.
If still no response, call Campbell Scientific.
6.2.2 NO RESPONSE FROM DATALOGGER
THROUGH SC32A OR MODEM PERIPHERAL
At the datalogger:
A.
Make sure the battery has been installed, and
the power switch, if any, is "ON" (Section 7).
B.
Use a voltmeter to measure the voltage on
the 12 V and G terminals; the voltage must
be between 9.6 and 16 V DC.
C. Make sure the datalogger is connected to
the modem, and the modem is properly
configured and cabled (Section 9).
At the computer:
D. Make sure the Station File is configured
correctly (PC208 Manual).
E.
Check the cable(s) between the serial port
and the modem. If cables have not been
purchased through Campbell Scientific,
check for the following configuration using
an ohm meter:
25-pin serial port:
computer end
modem end
