SECTION 5
SOLVING PROBLEMS
5.2 Common TC Head Problems
NOTE:
Always switch power off before connecting or disconnecting the TC head.
If the connector is damaged, electrical connection may be compro-
mised or fail altogether. A failed connection produces an ERROR
message on the display, as with a broken thermocouple. A poor
connection can cause erratic performance.
If the source of difficulty is still unknown, at least the most frequently
occurring problems will have been eliminated.
Testing Osmometer Performance
1
Reinstall the TC head to continue troubleshooting.
2
Set the instrument up using the procedure outlined in Section 3.
3
Allow 30 minutes for thermal equilibrium.
4
If you have a problem performing any of the steps of the setup
procedure, a malfunctioning electronic module is likely. Contact
Wescor or your dealer for assistance. Replacement parts are
available for user installation, or the entire instrument can be
returned to Wescor for repair. Loan instruments are available
from Wescor if needed. Refer to Section 1.2.
