NOTE Should it become necessary to move the instrument to another
location after the heat transfer fluid has been installed, take
appropriate precautions to prevent fluid spillage.
Step 8 — Run self-diagnostic test
During power-up, the scrolled display, “ Press START to Continue ”,
indicates that the instrument is required to check for proper operation by
running a test sample in a cassette. Only a single sample will be run at
this time. The instrument operator should load and start the self-
diagnostic test as follows:
1. Pipette or measure a 0.2 to 0.3-mL sample (H
2
O is OK) into a sam-
ple tube and place it in the first position in a sample tube cassette.
2. Place the cassette in the left (input) deck (see figure 4) with the cas-
sette identification number facing you.
3. Press START.
While the self-diagnostic test is running, “
Running Diagnostics ” is dis-
played. When the 3900 has completed the self-diagnostic test,
“ Osmometer Ready ” is displayed and the instrument is ready for regu-
lar testing. Please turn to Chapter 2 for operating instructions.
If the probe data has been lost from memory, “ Reset Probe
Configuration ” will be displayed and printed, the instrument will
switch to the SETUP menu and one should contact Advanced Hot-Line
®
service before proceeding further.
Step 9 — Proceed to instrument operation
If you have followed the steps outlined in this chapter, your instrument
is ready for use. To learn how to operate your instrument, read the next
chapter, Instrument Operation . We strongly recommend that you read
the entire second chapter before attempting to operate your osmometer.
