Osmometer Model 3250 User’s Guide
Note In emergency, H
O may be used in place of bin-setting fluid
for this test. The bin number thus determined will be
acceptable for bin-setting though the probe resistance
displayed is that at the freezing point of the H
O sample
used, and will be different from that for bin-setting fluid.
20. Record the sample probe resistance and bin number in the Service
Log at the end of this user’s manual; then press the STOP key. The
display will change to Probe Bin Test.
21. Press SETUP to enter the SETUP menu, then repeatedly press the
key until the display reads Set Sample Bin #.
22. At Set Sample Bin #, press the START key. The display will report
the current sample bin number setting.
23. If the current sample bin number setting is not the same as that just
determined, enter the correct bin number by means of the numeric
keypad; then press the ENTER key. The display will change to Set
Sample Bin #; then press the STOP key to return to Osmometer
Ready. If the current sample probe bin setting is the same as that
just determined, simply press the STOP key twice to return to
Osmometer Ready.
24. Press the CALIB key and calibrate the instrument as recommended
in Chapter 4. Recalibration is required each time the sample probe
is replaced.
