CT-2000 Instruction Manual
Troubleshooting
A successful CT-2000 self-test is an indication that there are no detectable errors and checked
components are functional. There are certain conditions, however, that cannot be verified by the
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 (bath liquid viscosity, temperature probe
installation and motor-stirrer functionality) may cause incorrect temperature stability. If items 4 or 5
fail (temperature probe functionality and/or heater operation), the bath may be non-operational.
Consult Table 4 for assistance in troubleshooting your CT-2000. If the following table fails to resolve
the difficulties, call your local CANNON representative for assistance.
