MODEL CT-

2000 PROBLEM ANALYSIS

A successful CT-2000 self-test is an indicator that there are no detectable

errors and checked components are functional . There are certain condi-

tions, however, that cannot be verified by these automatic tests. These

include:

1. Viscosity of the bath liquid.

2. Temperature probe installation

3. Motor-stirrer functionality

4. Temperature probe functionality

5. Heater operation

Problems with the first three items listed above may cause incorrect

temperature stability. If items 4-5 fail, the bath may be non-operational.

Fault isolation
