Troubleshooting the STA Compact – Service Part 4

All right. Now, the next position is for the Microtainer, position F4. I'm not sure we want to do that, but hey. (Narrator removes and replaces Microtainer, :10) This is what determines how far the unit, the Z movement . . . how far it will go down the needle if you have a Microtainer. If you choose Microtainer, Microtainer, (Narrator shows Microcup, :23) not Microcup, Microtainer, put it in the unit. I usually use the Microtainer that they use because some people use other products other than Stago. So, I use whatever is at the customer's site.

I'm going to choose F2 to adjust it, F10. The only thing this even allows you to do is the Z movements. Now, you can see if I push this, (Narrator manually adjusts needle, :49) I'm basically, to adjust the down movement. You can see if I had a larger Microtainer, or I pushed it down or something, how my down movement could change from one Microtainer to the other. This is what's going to determine how far, the maximum that needle number one can go down, if you were using the Microtainer. That's assuming that you choose Microtainer. We're all the way to the bottom. Hit F10 to validate.

It's going to go to home position. We'll do a test, just because we did with the other one. I'm not saying there's any reason to do this, at least not for my eyes. (Narrator adjusts Microtainer, 1:39) You can see them all the way to the bottom here. Anyway, onto the next step. (Narrator removes Microtainer, 1:48)

Let's see. We're not going to do... You got a position for drawer number one, needle number one. That's for neonatal tubes. We're not going to do that. Same basic principle. Position eight, drawer number one. That's for your Owren Koller Buffer. We'll do that just because we're here. F2. Not one that I worry about too much. (Narrator places mapping cuvette in STA Compact, 2:16)

Put your mapping tool in position eight, drawer number one. Again, read the screen. (Narrator manually adjusts needle into mapping tool, 2:27) In theory, this should go right into the middle. It's a little off, not much. This only can go really Z. I'm going to put it all the way down to the bottom. By the way, this is a good spot to see that the red light for liquid level detect comes on. I don't know if you can see that red light there, (Narrator points out red light on arm 1, 2:53) but that just tells you your liquid level detect is working. That should come on at the bottom of these mapping tools. Hit F10. It goes straight up.

We're not going to test it in this particular position. For one, there's no X, Y, or Z movements, and I don't want to bend another needle. (Narrator removes mapping tool, 3:14) Let's start all over again. So, now this is a key position, drawer 2, position 11. (Camera pans to computer, 3:23) When you get to the mapping, notice that, again, this is the only position that you map needles one, two, and three. Everything else is needle number one. That's because it takes this as a reference.

Position 11. This is the key to making sure that all your mapping for all your needles is proper. (Camera pans to STA Compact, 3:41) We're going to take our mapping cuvette, (Narrator places mapping cuvette in position 11, 3:43) put it in needle number one. Excuse me. Put it in position number 11. F10 to validate. Excuse me. Enter. F2 to adjust. F10 to validate. Got a little ahead of myself.

Okay. Needle number one goes over it. (Narrator manually adjusts needle, 4:09) This should . . . When I come down, it should go into the center. If you're going to be critical, this is the spot to be critical. Generally, I take a flashlight, and I get my head right over it so that I know that it's in the center. I want to move it a little to the right. Again, remember we also straightened that needle. So, in theory, we got . . . (Narrator manually adjusts needle, 4:36-5:20) We know we got a straight needle, which is a problem when you got needles that have been bent, but okay.

I'm going to go back one. I want this as dead center as I can physically get it. I'm going to go back again, using your arrow keys. I have no problem sticking my head in here. Okay. Now, we want to go all the way down to the bottom. Note, all the way to the bottom. Note my red light comes on. That has to come on, by the way. When it goes down, that's what's going to determine that it's down. It hits the bottom of the mapping cuvette.

Have any problems, by the way, with mapping cuvettes, take the copper piece off the bottom and clean it with a little emery cloth or something. After time, the mapping cuvettes get crudded up and don't work well.

All the way to the bottom. Going to hit F10 to validate. See it going back and test it. You know, I'm so sure of the mapping on this one, and I'm not suggesting you do this because this is a good way to end up replacing a needle, but for testing purposes, we're going to go test F3. I'm going to even leave my mapping cuvette. I'm brave here. There it goes. I would not do that. I'm just showing you that, in theory, that it works well. (Narrator shows needle response, 5:48) I'm all the way to the bottom here. As you can see, I can't pull it up, and that's the way it should be.

Now, onto needle number two. Again, position 11 is the only spot you do all three needles. It takes that and uses it a reference for all needles. I think one of the things I'd like to point out is since this is the only reference spot, if you're off on your mapping here with just needle three. Here is where you can adjust needle three. This is your reference point, for lack of a better way. I'm not sure if that explains that properly. But if you want to just move needle number three a little, even on the measuring block or anywhere else, you need to change it here because it doesn't give you the option at other locations.

If all of them are off, then you can kind of assume that it's in reference to needle number one. In other words, (Narrator manually adjusts needle, 6:52-7:20) this is the 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. You'll see when we get into even the measurement block. You don't use measurement three. You use needle number one.

Again, I crawl, get right over it because I want it dead center. F10 to validate. My red light is on. (Narrator points to red light, 7:23) If you watch it go up and down there, comes back on, we're good mapping. If it’s starting to chatter or something in there, you'd get a problem because that's the way that should work.

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. (Narrator manually adjusts needle, 7:58-9:04) Again, this should go in the middle. This is the problem. Remember, this was the one I had the problem with on the last video. 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. So, I straightened that when I did the mapping for the washing.

I'm going to pull it over just 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, I have 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. That's my liquid level detect. I'm going to hit F10 to validate. Went down. Saw it. Now, it's going to go to home position. (Narrator removes mapping cuvette, 9:11)
