These tests assume that the F4 Controller’s setup and tuning values have not been changed from the values as shipped from TestEquity. Also, the EZ-Zone Limit Controller high limit must be set to over +85°C (+88°C would be fine), and the low limit set to –75°C. 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. -

Page 57: How To Verify The Temperature Calibration
How to Verify the Temperature Calibration TestEquity recommends verifying the temperature calibration before attempting to actually perform a calibration. The state-of-the-art instrumentation used in TestEquity chambers is of the highest quality and seldom goes out of calibration. If you try to calibrate the instrumentation before determining that calibration is necessary, you may make it worse if done incorrectly. -
