Troubleshooting the STA Compact – Service Part 5

In other words, this is a reference point. All the other spots are referenced to this. This is the only spot that you map needles number two and three. All other ones are needle number one. (Narrator manually adjusts needle, :16) You'll see when we get into even the measurement block. You don't use measurement three, you use needle number one. Again, I get right over it because I want it dead center. F10 to validate. Our red light is on, (Narrator points to red light, :32) and if you watch it go up and down there, it comes back on. We're good mapping.

It's starting to chatter or something in there, you get a problem. Because that's the way that should work. It goes to home, now the same thing for needle number three. Needle number three, F2 to adjust, F10 to validate, needle number three goes over. And again, this should go in the middle. (Narrator manually adjusts needle, 1:08-2:11)

This is the problem. Remember, this is the one I had the problem with on the last video. And it should go right in the center, which it pretty much does. And again, remember, I straightened the needle. So I don't need to make any adjustments to the needle, because I straightened that when I did the mapping for the washing.

I'm going to pull it just over one step to the right. I really try to be kind of anal here. Because this is just a little more critical. Again, this spot is critical because they use this for reference for all the other positions. All the way to the bottom, check, by the way, a warning.

Make sure all your mapping cuvettes always go to the bottom. Some of them are a little tight. I haven't seen that in a while, but they used to be. See the red light is on. (Narrator points to red light, 2:12) That's my liquid level detect. I'm going to hit F10 to validate. And now it's on, it's going to go to home position. (Narrator removes mapping tool, 2:20)

Now the next one is drawer 2, Micro Tube in position 11. I'm not going to worry about that. Just so you know, it's the same basic principle that you're doing for when they use a micro cup. When you put a micro cup in there, that is what you're mapping. And again, it's the same basic principle. You're just looking to go to the bottom.

All right. Onward. Go to position 22. You're going to see that all of the mapping now is in sections. (Narrator points out mapping sections, 3:12) So they all take it, and it's only for needle number one, the base needle two and three on needle number one. And
they do it in sections. This back section, this section, the front section. So, we're going to position 22.

F2 to adjust, because we're probably not going to do all of the positions for this training film, because simply it will make it too long. (Narrator places mapping tool in position twenty two, 3:39) Position 22, make sure it's all the way to the bottom. F10 to validate. (Narrator manually adjusts needle, 3:49-4:48) See? Only needle one is available here. It should go right in. Most of the time it does. These aren't really in my eyes that critical, although I generally do get right in the middle, because this is what's going to determine it goes into that white hole that's in the cap to the reagents.

And generally, when I run endurance, I kind of watch those holes. Because I can go back and make a minor adjustment if they're a little off. But again, you're making the adjustment to one, not to two and three. And again, you want to go all the way to the bottom because that is what's going to determine how low it goes in the vial.

So if you're having problems where they say, "Oh, it's leaving too much reagent." It's because it's not mapped right. It goes all the way down, my red light comes on. F10 to validate. Red light came back on. And we'll be brave here, because I have faith in my mapping. Do not do this. (Narrator show that the mapping tool can’t move, 5:08)
All right. All the way to the bottom. I can't raise my adapter or my mapping tool, I should say. Okay, so I know that position's right.

And you would go through all the positions. And we're going to skip a little here because it's the same for all the positions. And I don't worry too much about these because again, it's going to have an effect on where it goes into the reagent bottle. (Narrator removes mapping tool, 5:27)And you've got a pretty big hole in the top of that cap.

We're going to move down to the cuvette. And if you see on the screen, let's see if we can get a picture of the screen here. (Camera pans to computer, 5:40) A cuvette, it only does needle number 1, incubation Position 16. (Narrator points to highlighted text, 5:43) That's the only one. And so it takes reference from needle number one to...
