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
