The "Display" pushkey can also be used to obtain a displayed read-out
of data stored in the Memory.
Initiates a programming sequence for selecting parameters to be mea-
sured and recorded. The Type 1213
automatically divides the selected
measurement period into
60
equal intervals. Measurements are made
and stored at each
interval. For air velocity measurements a
60s
lin-
ear average is recorded
if
a 1 hr recording period is selected, but for
all other recording periods the
3-minute
linear average is recorded.
When in the
"Record" mode, the "Record" pushkey may be used either
to put the Type 1213 into a
low-power
mode where most LEOs are
extinguished, or
it
can be used to display the elapsed measurement
time. These functions
alternate each time the "Record" pushkey is ac-
tivated. The
Analyzer automatically reverts to the
low-power
mode
if
no pushkey has been activated for 4 minutes.
Is used to recover stored data from the Type 1213 memory. When
pressed, the user can
replay stored data, either on the Display
or
via
the outputs on the Rear
Panel. If the Display is selected, the
"Replay/Plot" pushkey is used to step through the data stored in the
memory.
If the Rear Panel outputs are selected, "Replay/Plot" is used
to obtain
"Zero" and "Gain" calibration signals for the
X-Y
Recorder
and
also to initiate data plotting once the parameters have been
selected.

Four pushkeys for the selection of the recording time. One pushkey has the additional
function
of
changing the measurement units from
Sl
to Imperial and vice versa.

Used to select a
one-hour
recording period. When selected, measure-
ments are made every minute.
In
the "Display" and "Replay/Plot"
modes this pushkey cannot be used.
Used to
select a
six-hour
recording period. When selected, measure-
ments are made every six minutes.
In

modes this pushkey cannot be used.
Used to
select a 24-hour recording period. When selected, measure-
ments are made every twenty four minutes.
In
the "Display" and
"Replay/Plot" modes this pushkey cannot be used.
