Okay; probably okay, Fred. Read it nice and slow so we'll be sure to get it. Over.

Okay. Jack pushed in the 250 BAT A, BAT B entry breakers. He read battery bus volts as 32.3 on A, 37.0 on B. Then he pushed in the 275 breakers tying the BATs to the main buses. In this configuration, MAIN A is at 32.0 volts, zero amps; MAIN B is at 37.0 volts, zero amps. So it looks like the buses are okay.

Okay, Fred. Copy those numbers and thank you very much. I assume you got them off all right.
-
Fred Haise (LMP)
-
Okay. Let me know when you want me to try it.

Okay. I'd just like to … how's—how's our lith-o cartridge setup … appear to be working down there.

Joe Kerwin (CAPCOM)
-
We are reading 0.2 on our CO2 sets here, and we're all delighted. It seems to be working fine.

Joe Kerwin (CAPCOM)

And Fred, Houston. In a little while here, I'm going to have a procedure that I want to read up to you and have you copy down for future use. It's a procedure for powering the command module main bus off the LM, and it's something that we feel that's going to come in real handy later on for such things as popping off the command module entry batteries, and also possibly for doing some preheating and preliminary powering up of the command module before we get rid of the LM. We'll have that for you in probably 10 or 15 minutes. Over.

Fred Haise (LMP)

Okay, okay, Joe. That's good. Sounds good.

Okay, Fred. Our procedure-generating mill has generated another very short one for you here. It's a procedure for getting an onboard read-out —
-
Joe Kerwin (CAPCOM)
-
Okay, Fred. This is a procedure for getting a read-out of the descent propellant tank temps. It's no big problem, but our LM people say that the bottom of the descent stage is probably cooling off, and we just want to verify that the descent water tank will be okay. Right now, it looks as though it won't freeze until several hours after it's empty, but we want to have you read these temperatures out to us so we can see how good our predictions are. The procedure is, on panel 16, close the PROPELLANT DISPLAY/ENGINE OVERRIDE LOGIC circuit breaker. Over.
-
Fred Haise (LMP)
-
Okay. The PROPELLANT DISPLAY OVERRIDE circuit breakers are closed. … the propellant.
-
Joe Kerwin (CAPCOM)
-
Right, Fred. The next step is simply to turn the PROPELLANT TEMP PRESS MONITOR switch to DESCENT 1, read the fuel and OX temps, turn it to DESCENT 2, read the fuel and OX temps; tell us what they are.
-
Joe Kerwin (CAPCOM)
-
Okay, Fred. We're in noisy COMM here; I got DESCENT 1 fuel 66.5; stand by a second.
-
Fred Haise (LMP)
-
On DESCENT TANK 2, fuel is reading 60—Okay. DESCENT 2 fuel is reading 68 degrees; oxidizer, 65 degrees.
-
Joe Kerwin (CAPCOM)
-
Okay. Copy that, Fred. Thank you. We'd like you to pull the circuit breaker, and we'll probably come to you again in 5 or 6 hours for another check.
-
Joe Kerwin (CAPCOM)
-
Okay. We're chasing a small glitch that we saw a while ago in the O2 flow rate which is now normal again, but what we'd like you to do is, first of all, to tell us whether, during that canister procedure, you moved O2 DEMAND REG A to any position other than CABIN, and then we'd like you to move it to OFF momentarily and back to CABIN for us.
-
Fred Haise (LMP)
-
Okay. To answer your question, Joe, it's no. I checked the CABIN all the time. Qualitatively, when we switched to this configuration, it didn't seem like the frequency or the suit fan noise … decreased … logged down a little bit, but I'll follow your procedure. You want me to take REG A, go to close and back to CABIN; is that correct?
