具体实施方式detailed description
下面结合附图对本发明做详细说明。The present invention will be described in detail below in conjunction with the accompanying drawings.
参考图2，外接28V直流电源，经28V-5V电压转换模块，将28V电压转换成直流5V电压给系统供电。5V电压通过各电位计进行调整至总温指示器各测试点所需模拟电压，最终测试电缆将模拟电压直接加到总温指示器上，对总温指示器的测试点进行检查。Referring to Figure 2, an external 28V DC power supply is connected, and the 28V-5V voltage conversion module converts the 28V voltage into a DC 5V voltage to supply power to the system. The 5V voltage is adjusted to the analog voltage required by each test point of the total temperature indicator through each potentiometer, and finally the test cable directly adds the analog voltage to the total temperature indicator to check the test points of the total temperature indicator.
试验前先将总温指示器试验器接到28V直流电源上，在将总温指示器接到总温指示器试验器的接口上。试验器面板上的开关处于打开状态。闭合试验器总电源开关，接通28V，开始试验。调整电位计的电压，当在电压表上读到0.156V电压时，停止调整，对总温指示器进行检查，如总温指示器指示-50±1℃则满足总温指示器精度要求；以此类推，调整电位计的电压，当电压表指示0.625V时总温指示器应指示-20±1℃；调整电位计电压，当电压表指示1.093V时总温指示器应指示10±1℃；调整电位计电压，当电压表指示1.562V时总温指示器应指示40±1℃；调整电位计电压，当电压表指示2.031V时总温指示器应指示70±1℃；调整电位计电压，当电压表指示2.484V时总温指示器应指示90±1℃。Before the test, connect the total temperature indicator tester to the 28V DC power supply, and then connect the total temperature indicator to the interface of the total temperature indicator tester. The switch on the tester panel is on. Close the main power switch of the tester, connect 28V, and start the test. Adjust the voltage of the potentiometer. When the voltage of 0.156V is read on the voltmeter, stop adjusting and check the total temperature indicator. If the total temperature indicator indicates -50±1°C, it meets the accuracy requirements of the total temperature indicator; By analogy, adjust the voltage of the potentiometer, when the voltmeter indicates 0.625V, the total temperature indicator should indicate -20±1℃; adjust the potentiometer voltage, when the voltmeter indicates 1.093V, the total temperature indicator should indicate 10±1℃ ;Adjust the potentiometer voltage, when the voltmeter indicates 1.562V, the total temperature indicator should indicate 40±1℃; adjust the potentiometer voltage, when the voltmeter indicates 2.031V, the total temperature indicator should indicate 70±1℃; adjust the potentiometer Voltage, when the voltmeter indicates 2.484V, the total temperature indicator should indicate 90±1℃.
