Instrument Display

A single, multifunction display meter in the upper center of the front panel serves
to display the following (selected by pushbuttons below the display):
• surface area for single-point analyses
adsorbed gas volume for multipoint analyses
•
• degas temperature during degassing
•
detector signal
Clear SA Display
pushbutton
The signal chosen for display can be shifted at any time in any sequence without
detriment to the other signals. Surface area information and gas volume data,
whether displayed or not, are retained after a test is completed until the Clear SA
Display button to the left of the meter is depressed.
Surface area and adsorbed gas volume are displayed in terms of the quantity of
sample contained in the sample tube. This means the displayed number must be
divided by the sample weight to convert it to specific surface area (m
cific volume (cm
The detector signal is calibrated to indicate the instantaneous difference in percent
nitrogen between the reference mixture and that currently in the detector. The x1
scale indicates differences up to 100% while the x10 scale indicates a maximum
difference of 10%.
The degas temperature is displayed as degrees Celsius.
The FlowSorb III 2310 has two additional pushbuttons below the display meter.
The Start push button is depressed after the degassed sample has been trans-
ferred to the Test position for analysis. The Reset button is used to abort an
analysis; the analysis stops and the instrument returns to initial conditions.
