Do not attempt to modify the setup values, unless you thoroughly understand what you are doing. If there is any doubt, please call TestEquity before proceeding. TestEquity TEC1 Thermoelectric Temperature Chamber... - Page 6 ! CAUTION: NEVER select “Factory Default” in the Diagnostic Menu. “Factory Defaults” are NOT the TestEquity configuration parameters for this chamber. If you select “Factory Defaults”, you must reconfigure all System and Operation Parameters as documented in the TestEquity manual, NOT the “EZ-Zone PM User’s Manual”.

Chapter 2 – Installation Chapter 2 – Installation Unpacking Inspect the shipping container for any signs of visible damage. Notify the carrier and TestEquity immediately if there are signs of shipping damage. 1. Cut the bands that hold the packaging together. -
Page 8: Condensate Drain
Condensate Drain can be ignored. Input Voltage Configuration (Does not apply to model TEC1-001, which is only rated for 115V input) This chamber can be configured for 115V (88 to 132VAC) or 230 V (176 to 264VAC), 50/60 Hz input. The chamber ships pre-configured for the correct input voltage based on the county it ships to. -
Page 9: Chapter 3 - Operation
The rear panel has a convenience outlet. It is provided for the AC power adapter for the GPIB or Ethernet interface converter only. The power is unswitched and is the same voltage as the outlet that the chamber is plugged into. Thus, the TEC1-001 is rated for 115 V input only.

Page 10: Loading The Chamber
To prevent damage to your test sample and the chamber’s thermoelectric devices, do not exceed the live load rating of the chamber. Live Load Rating Temp +37°C +23°C +15°C +10°C Watts 90 W 50 W 35 W 20 W Page 3-2 TestEquity TEC1 Thermoelectric Temperature Chamber... -
Page 11: Performance Considerations
Make sure that all connectors, wiring, pc boards, and auxiliary components can withstand the temperature extremes that they will be subjected to. In some cases, these components may not be able to last after repeated tests and should be considered expendable. TestEquity TEC1 Thermoelectric Temperature Chamber Page 3-3... -

Page 26: How To Verify The Chamber Performance
Temperature Controller’s setup and tuning values have not been changed from the values as shipped from TestEquity. If the chamber fails any of these tests, it should be removed from service to prevent further damage until the cause of the problem is determined and resolved. -

+0.5°C These would be considered as being within the specification limit of ±2.0°C. TestEquity typically enters a Calibration Offset value of -0.5°C to -1.5°C in order to achieve the results above. If calibration of the temperature controller is necessary, refer to page 56 of the “EZ-Zone PM User’s Manual”... -
