be an incorrect number entered in the "Config Sensors" submenu or there may not be a good
connection to that sensor.
2. View logged data for each sensor and make sure the values are correct.
3. Use a DVM to insure the charging voltage is present.
4. Go to the "Inspect System " menu and then to the "Display Status" submenu. Perform a
Display Status and verify there are no error messages, tripped failsafe, or any other message
which would lead you to believe that something may be wrong with the 8310. Also observe the
messages which provide the Transmission (Random and Self-Timed) schedules and make sure
the next Tx times are going to occur when you believe they should. Note the number of resets
and use this as a reference for later visits.
5a. If you have a GOES unit, it is advisable to perform a forced transmission to ensure proper
operation of the Goes transmitter section and verify the external battery has enough capacity to
allow a transmission. Make certain when forcing self-timed transmissions, that you transmit
into a dummy load to keep from interfering with another DCP. Connect a voltmeter directly to
the battery and observe the voltage drop while the transmissions are taking place. If the voltage
drops much more then 1/2 of a volt, the battery is suspect and should be changed to avoid
future problems. When forcing random transmissions, it is advised to transmit through the
antenna and verify your downlink received it before you leave the general location of the site.
5b. If you have a telephone system, have someone dial the station, make sure it answers in the
proper mode and communicates the data properly.
5c. If you have a LOS radio system, have the base station poll the station and display the system
status to look at communications statistics.
6. Contact the base station to make sure data are being received properly.
7. Make sure the date and time are correct. The time for GOES units should be exact.
8. Make sure the Recording ON message is displayed (or ON&TX) for GOES units.
GOES Antenna Pointing
Refer to the Satlink manual for information on pointing the GOES antenna.
