All the operating procedures of the test are performed within the test standard range value. The high and low temperature test chambers perform the operation of mutually adjusting the test data in the equilibrium state, which can more accurately detect the subsequent test results. Because the occurrence of certain conditions may cause its tests to fail to function properly, how much loss is immeasurable. It is most critical to ensure that the test is carried out properly with all preparations in place.
It is necessary to check whether the scanning line of the high and low temperature test chamber is in a horizontal state. If not, it is necessary to adjust the horizontal balance rotation. The impedance of the probe is matched and its impedance matching section should be adjusted before its probe is used. There is a tunable capacitor at the end of the probe near the oscilloscope, and some probes can also have adjustable capacitance near the end of the probe. It is used to adjust the impedance matching of the oscilloscope probe. If it does not match, the measured waveform will be deformed. When we measure the higher pressure, we can use the X10 function of its probe to adjust the Y-axis gain rotation so that the peak value of the waveform is around 1/2 screen width. When the scan time knob is adjusted, it allows the waveform to be displayed for about 2 cycles. If you can't see the waveform on the pin with its oscilloscope, it may be because the probe X1 is used, and its higher voltage is attenuated to enter the oscilloscope. The input impedance of the X10 gear is much higher than that of the X1 gear, so when testing the signal with weaker drive capability, the probe is measured to the X10 gear.
When debugging the signal wave files of the high and low temperature test chambers, it should be based on actual conditions. In the correct method, the X10 file of the probe should be used, and no other problems will occur.
