Recall results
The recall results feature of the Model 3300 allows you display or print
the results of your last 30 tests. If you need to see any or all of these
results, take the following steps.
1. At “ Osmometer Ready ” , the two multifunction soft keys are labeled
[CALIB] and [DIAG] , respectively. Press the soft key labeled
[DIAG] to enter the diagnostic test menu.
2. While you are within the diagnostic test menu, the soft key labels will
change to [START] and [INDEX] . Use the [INDEX] keypad to cycle
through your choices until you see “ 1. Recall Results ” .

Instrument Operation
Repeatability Tips
•
Treat all samples, as well as standards and reference solutions, uni-
formly before the test.
• Microsamples are more susceptible to contamination and evapora-
tion than larger samples. Avoid leaving sample containers open.
Cold samples are susceptible to condensation; warmer samples are
susceptible to evaporation.
• Use only the Advanced Model 3300 sampling system. Each sys-
tem comes with specific operating instructions and re-order infor-
mation.
•
If an occasional sample produces irregular results, discard obvious-
ly discrepant readings as long as the instrument has been producing
accurate readings repeatedly. Repeat the sample in question.
• For repeat runs, use additional samples from the same source.
•
Keep the cooling chamber clean between tests. Never inject any-
thing into the cooling chamber.
