Control circuit through the loading or unloading coolant compressor and make the air-freeze agent in the heat exchanger compressed air temperature constant.
控制电路通过加载或卸载冷冻剂压缩机而使空气-冷冻剂热交换器中的压缩空气温度保持恒定。
DVM usually got an input impedance of 10 Mohm. There may be loading effect when measuring high impedance circuit.
数字式电压表通常有10兆欧的输入阻抗。当测量高阻抗电路时﹐可能会有影响。
X1 probe: no attenuation, input impedance follow that of scope input impedance (usually 1 Mohm). This type of probe is seldom used because of heavy loading effect on circuit under test.
X1探头﹕没有衰减﹐输入阻抗跟示波器输入阻抗一样(通常是1兆欧)。由于对测试电路有很大的负载影响﹐所以很少使用这种探头。
