对于电子线路的故障排除和调试,图1中的简单温度测量探头可充当一种不可缺的工具。如需测量几个点的温度,可为IC1(Maxim MAX6610)配备一个探头,或者可以永久地将一个或多个器件整合到印制电路板上,或把它们连接到各个元件。电阻器R1、R2、R3把电路的温度定标电压输出设定为各个值(表1)。图2展示了电路在各个温度的代表性输出。 For troubleshooting and commissioning of electronic circuits, the simple temperature measurement probe in Figure 1 can serve as an indispensable tool. To measure the temperature at several points, a probe can be provided for the IC1 (Maxim MAX6610), or one or more devices can be permanently integrated onto a printed circuit board or connected to various components. Resistors R1, R2, R3 set the circuit temperature scaling voltage output to various values ​​(Table 1). Figure 2 shows the circuit’s representative output at various temperatures.
