FAQ
Lamps
Q: What do you have to consider after a Standard Lamp bulb change?
A: Ensure brightest part of the band of light is sitting in the middle of the Iris. There are two ways to accomplish this.
Micrometers
Q: How do I find the micrometer offsets if I don't know where the HG emission lines are??
A: Finding Micrometer Offsets from Scratch
Q: What should a grating scan look like when plotted?
A: Troubleshooting Grating Scans
Foreoptics
Q: What direction does the correction len(es) go?
A: Object should appear tall and thin and concave surface should be facing (Direction of light travel) towards the slits or PMT
Correction Lens
The correction lens [LE 5] has a convex-cylindrical surface (radius 170.0 mm) and a concave-spherical surface (radius 230.0 mm).
Both surfaces are coated with a layer of magnesium fluoride to minimize reflectance at 315.0 nm for an incidence angle of 29°. The lens is mounted in the entrance-slit housing at an angle of 29° to the optical axis with the concave-spherical surface facing the entrance slit. The axis of the cylindrical surface is positioned in the horizontal plane to within 1°.
Old Electronics
Q: What are the differences between new vs old temperature circuit on the clock board?
A: Note the resistors on the top left of the boards below (New Vs Old). New temperature circuits, some resistors has been replaced with a jumper wire.
Q: What is the differences between new vs old temperature circuit on the SPS board?
A: Old circuit . Power Supply - R601,604 and 605 are 11M and R602,606 and 607 are 1.6M and detect a temperature range of -30C to +50C
New Sec. Power Supply - R601,604 and 605 are 825K and R602,606 and 607 are 3M and detect a range from -33.27C to +59.93C

Schedules
Q: How do you disable the az check at the start of a the schedule?
A: Inside the skc.rtn, in line 11022 (about 18 lines from the top), add the instrument number you would like the program to ignore. Note: You may need to add it into the master program directory or disable the instrument from getting its program updated daily.
