Warranty Information
GE Kaye Instruments warrants its products against defects in materials and workmanship for a period of 12 months from the date of shipment.
The Kaye CTR-80 is an ultra-low temperature bath designed for stable temperatures in calibration and other applications. It features a solid-state controller for extreme stability, an 8-digit LED display, four key-switches for user interface, and RS-232 digital communications. The bath operates over a wide temperature range from -80°C to 30°C and 50°C to 100°C. Key operations include setting the temperature, using the power switch, and understanding the cooling function. It requires careful setup, including filling with appropriate fluid and ensuring proper environmental conditions.
Troubleshooting and error codes
| Situation | Suggested Action |
|---|---|
| Incorrect Temperature Reading | Power the unit on and watch the display. If the first number displayed is less than "-0005-", the unit has been re-initialized. The unit needs to be reprogrammed for R0, ALPHA, DELTA, and BETA. These numbers can be found on the Report of Calibration that was shipped with the unit. |
| The unit heats slowly | Check the Scan and Scan Rate settings. The Scan may be on with the Scan Rate set low. |
| Display flashes any of the following errors: "err 1" to "err 7" | Cycle the power off and on again. If the unit repeats the error code, contact GE Kaye Instruments Customer Support for a return authorization and for assistance. |
| The bath does not turn on | If a fault condition exists upon application of power, the bath will not energize. This bath needs to be plugged into the line voltage for at least 2 minutes before turning power on. This is only necessary for the first time that the bath is energized or when it is moved from one location to another. |
| High/Low voltage condition | If a High/Low voltage condition exists for longer than 5 seconds, the compressor will be de-energized. The controller display will flash "Lo LinE" o and off while the condition exists. Re-energization is automatic upon correction of the fault condition and after a delay cycle of about 2 minutes. |
