- | Firstly, check the schedule summary printout and find out which is the first scan to finish after the start of the check period (check times for each antenna are given at the top of this page). The idea is to stop the schedule while no data are being recorded. For example, if the check time is 19:00 UT, then in the schedule below, it could be halted after 19:05:45 UT but before 19:07:43 UT: | + | Firstly, check the schedule summary printout and find out which is the first scan to finish after the start of the check period (check times for each antenna are given [[operations:documentation_ops2_cont14|on this page]]).

+ | - Check the status of the backup generator via the System Monitor interface for the Hobart 12m. The default mode is "In Auto, off" which means it's ready to turn on if there's a power failure but it's currently switched off. If it's in any other state, query it with the On Call person. | ||
+ | - Check the maser. See the[[operations:maser_check|Hydrogen Maser check]] notes | ||
+ | - Make sure Skype is running to allow a chat session with all participating sites plus the on-call person | ||
+ | - Use the "Audio test" button on the log monitor to check the alarms are audible. | ||
+ | |||
+ | - check the receiver position with ''rxpos''. Should be -256, +248, +18 (x,y,z) | ||
+ | - Use the remote controllable camera [[http://ptzhb.phys.utas.edu.au|ptzhb]] to view the MarkIV rack for some of the next steps. | ||
+ | - Check all the Video Converters (VCs, or BBCs) are happy, ie no red lights and no nasty messages appearing in the log. Command ''valarm'' will turn off any remaining alarm lights on the VCs. | ||
+ | - Chronic errors that can be ignored can be silenced with:<code>check=*,-vf | ||
+ | check=*,-ifd | ||
+ | check=*,-v1</code> | ||
+ | - Check that if3 is happy with no red lights. You may need ''if3=alarm'' | ||
+ | - Check the formatter error light is off. You may need to do ''form'' | ||
+ | - Check that power reading for each VC USB (Upper Side Band) is between 0.1 and 1.0 volt | ||
+ | - Check Tsys with the ''caltsys'' command works. Caltsys should return results between 50 and 70K except possibly for RFI affected S-band channels | ||
+ | - Check that fmout-gps works with a ''clkoff'' and that it's about 10 - 12 us | ||
