SECTION 6. MAINTENANCE AND TROUBLESHOOTING6-2General Maintenance• An occasional cleaning of the glass on thesolar panel will improve its efficiency.• Check sensor leads and cables forcracking, deterioration, proper routing, andstrain relief.• Check the tripod or tower for structuraldamage, proper alignment, and forlevel/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 andET101/106 only). Replace if >5% off.2 years• Calibrate the solar radiation sensors (someusers suggest yearly).• Calibrate the temperature sensor.• Replace the wind vane potentiometer andbearings.4 - 5 years• Replace sensor cables as required.6.2 TROUBLESHOOTING6.2.1 NO RESPONSE USING THE KEYPADCheck keypad response after each of thefollowing 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 onthe 12 V and G terminals; the voltage mustbe between 9.6 and 16 VDC.C. Disconnect any sensor or peripheral wiresconnected to the 5 V and 12 V terminals.D. Disconnect any communications or storageperipherals from the datalogger.E. Reset the datalogger by turning the powerswitch to "OFF", then to "ON" ordisconnecting and reconnecting the battery.F. If still no response, call Campbell Scientific.6.2.2 NO RESPONSE FROM DATALOGGERTHROUGH SC32A OR MODEM PERIPHERALAt the datalogger:A. Make sure the battery has been installed, andthe power switch, if any, is "ON" (Section 7).B. Use a voltmeter to measure the voltage onthe 12 V and G terminals; the voltage mustbe between 9.6 and 16 V DC.C. Make sure the datalogger is connected tothe modem, and the modem is properlyconfigured and cabled (Section 9).At the computer:D. Make sure the Station File is configuredcorrectly (PC208 Manual).E. Check the cable(s) between the serial portand the modem.
