A higher resolution can be obtained by lining the zero volt signal up with the right-hand
side
of
the Recorder Paper
or
by changing the SENSITIVITY settings on the 2317.
Note: For the GAIN calibration the Level Recorder should always be connected
to
the
"Y-Out''
socket of the Analyzer. Therefore,
if
real-time
measurements
of
either instanta-
neous air
velocity,
or
incident radiation on the B face
of
the Radiant Temperature Trans-
ducer are required,
calibration should be performed using the
"Y-Out''
socket
of
the
Analyzer.
Once calibration
of
the gain has been accomplished, the Cable should be disconnected
from the
"Y-Out''
socket and reconnected to the
"X-Out"
socket
of
the Analyzer. The
2317 is now
calibrated and ready
for
use in the recording
of
measurements.
5.1.3. Real-Time Recordings Using Level Recorder Type 2317
1.
Connect and calibrate the Level Recorder as described in Sections
5.1.1
and 5.1.2.
2.
Connect the Transducers
to
the Analyzer as described in Section 3.4.1.
