NOTE
If the DMM stack voltage readings exceed the value
of the curve, it will be necessary to discharge the
TTS batteries by repeating steps 808 through 830.

Verify that the recorded MONITOR METER readings of steps 817 through
820 lies between or is equal to the high and low values extrapo-
lated in step 833.
