Separation plus 17 minutes, it had returned to 35. 2 volts. The F battery
voltage dropped from 36.1 volts (4. 35 volts) before launch to 33.6 volts
(4.05 volts) during the inadvertent turn-on When it was read at separation
plus 17 minutes, it had returned to 35. 7 volts (4. 30 volts). Thus the P bat-
tery voltage dropped approximately 1.6 volts and the F battery voltage
dropped approximately 2.5 volts, during the period from 030:12:17 (pad test)
to 030:15:51 (boost phase). This voltage drop was great enough to substanti-
ate a conclusion that the TV Subsystem was in the warmup mode during part
or all of the Channel 8 telemetry turn-on period.

Baseline drift and noise were considered in all readings. In reading the two
noisy frames at the start of the inadvertent telemetry turn-on, the baseline
drift was adjusted and the noise averaged. Based on the telemetry readings
made during the last two frames, it was concluded that both batteries were
supplying power in excess of what is normally required by cruise mode
telemetry and the backup clock. (Frame times are given in Table 5-6.)
It was agreed that the battery voltages during the two noisy frames were
probably lower than during the two following frames, but definitely no
greater.

Telemetry data showing Channel P unregulated voltage levels, LCR output,
and the F and P battery voltage levels during preflight tests and throughout
the flight are recorded in Figures 5-2 through 5-4. Temperature plots of
top hat, shroud, and F and P batteries are given in Figures 5-5 through 5-8.

C. ANALYSIS AND CONCLUSIONS

1. Inadvertent Turn-on

The Channel 8 telemetry stopped between points 2 and 3 at the end of the countdown test and started at point 3, after an RF dropout of all JPL telemetry channels. This RF dropout has appeared at this time on previous launches. The Agena link telemetry did not have an RF dropout and, on this record, the Channel 8 telemetry started between points 2 and 3. The Channel 8 telemetry stopped 67 seconds later between points 9 and 10 and came on again at the normal turn-on time (separation plus 17 minutes), starting between data points 9 and 10. Thus, it was concluded that the Channel 8 telemetry was on only during the time the data were received.

The turn-off of Channel 8 during the countdown was at three hours and thirty-four minutes before the time of the inadvertent turn-on of Channel 8 during launch. The telemetry points indicated a change of 2°F for the batteries, which was a reasonable change for that period of time. During the first ten hours of flight, the batteries increased in temperature
