Constant Temperature Test Chamber test and debugging method

A taxonomy of test criteria for each test execution should be maintained for each execution process. A temperature cycling chamber at equilibrium indicates a correct assessment of performance for a given data. Therefore, is a more accurate detection of the following test results. It does not function correctly due to certain conditions affecting its evaluation. This means an immeasurable reduction in inaccurate test results. This is why the importance of ensuring the expected behavior of this test in preparation cannot be overemphasized.

How to test and debug?

You need to test that the scan lines of the temperature cycling chamber are in equilibrium. Otherwise, you need to correct the horizontal balance rotation. The impedance of the probes should be part of their change before using its impedance. There is an adjustable capacitor on the same end of the probe near the oscilloscope. Some probes may also have adjustable capacitance near the probe. Used to correct impedance matching of oscilloscope probes. If it is not suitable, the measured waveform will be distorted.

How to solve the temperature overshoot of the temperature cycle Test Chamber?

The temperature overshoot of this temperature cycle Test Chamber refers to the phenomenon that when the temperature of the working room exceeds the set temperature from above 3°C, the temperature of the working room decreases slowly after the initial operation and stabilizes at the set temperature.

The corresponding temperature deviation requirement of ±3°C is constant or the overshoot of the temperature cycle Test Chamber is determined by the temperature of the test bench. For example, 0-100 °C temperature overshoot should not exceed 2 °C. More than 100? or above will not exceed 2% of the assessment period. The control tool of this gear is relatively simple, depending on the adjustment control accuracy. It contains the functions of automatic calculation, programmable and mass storage of historical data and curves.

After the temperature overshoot exceeds the conventional selection, it is necessary to contact the manufacturer to correct it in time. Otherwise, you can ask a third-party measurement agency to make an adjustment. After the temperature overshoot is too large, the manufacturer's accessories and production process of this thermal cycle will affect the unsuitable Test Chamber. Therefore, we remind customers not to pursue endless cheap equipment when purchasing equipment.
