26m Checklist
- Antenna : on source and tracking. Use the
onsourcecommand to check the antenna is where it should be, - * Time: Field System time (econtrol StatusMonitor) agrees with station time
- Time: Maser status OK
Check the “Standard VCH-1005A Manager” display on the Windows PC (to view it, start a VNC session via the Applications menu to timehb, Hobart 26m uses the same maser as Hobart 12m). Green numbers are good, red are bad. Here's an example of how it should look:
Report any red numbers to Brett ASAP. if you see mention of 'Battery', the maser has lost mains power and is running on it's UPS. If so, tell Brett immediately. - Mark5: disk_pos OK
The commanddisk_posin eRemoteControl should report two values - the current number of btyes recorded, and the number of bytes at start of previous scan. - Meteorology: Weather (wth) being logged
- Meteorology: Sky conditions logged (percentage cloud cover, rain etc)
- Tsys: S-band Tsys 50 to 70K
- Tsys: X-band Tsys 50 to 70K
- check the receiver position with
rxpShould be -256, +248, +18 (x,y,z) - Cryogenics. The command
cryomonwill return information on the S/X cryogenics. The lines to look out for are thepresand70kvalues…- Cryogenics: Vacuum pressure less than 3.5. The Vacuum pressure in the S/X dewar should be below this value (measured in microns of Mercury). If it increases above this value, it indicates a leak. Let Brett know. e.g. this readout indicates a vacuum pressure of 1.227

- Cryogenics: 70K stage temperature below 65K. The S/X dewar contains a 20K and a 70K stage. If the 70K stage temperature exceeds about 65K, this indicates the receiver is warming up and needs attention. Contact Brett. e.g. this readout indicates a 70K stage temperature of 167K (not good!)
2014.126.09:01:49.97/rx/1F(70k),on,a,on,on,on,off,locked,167.0
- Cryogenics: Helium supply pressure above 275 psi. Use a MONICA session on ''newsmerd'' to monitor the Helium supply pressure. If it drops below 275 psi, call Brett!
- Log Monitor audio check button sounds audible beep. Make sure you can hear the alarms
- Skype. Make sure Skype is running to allow a chat session with all participating sites plus the on-call person
- System: Check and update Handover and Current Issues wiki pages
- System: Any problems or concerns logged. Anything else of note? Put it in the log
