How to check fuse resistance with a multimeter In the left photo, the fuse is blown, the multimeter shows OL, which means no continuity or the resistance is higher than can be measured. In the right photo, the fuse is OK, so the multimeter shows 0 Ω or Ohm. Click on the image for...
在进行任何电气检查之前,首先要确保关闭相关电路的电源,以确保安全。 2. 使用万用表测量电压 (MeasureVoltagewith a Multimeter) 打开万用表,将其设置为交流电压模式,测量电路的电压。如果电压值正常,说明电源没有问题。 3. 检查绝缘电阻(Check Insulation Resistance) 使用绝缘电阻测试仪,测量电气设备的绝缘电阻值。...
2. Connect the digital multimeter to the load cell you want to test. 3. Using the multimeter, check: The value of the resistance between the positive signal wire and the negative signal wire. It must be the same as or similar to that indicated on the load cell data sheet (...
View the ohm reading on the multimeter's display. In most cases, the resistance shown on the display should be more than zero but less than 20. If the multimeter shows "0" on the display, no continuity exists between the two pins. This is usually the result of a damaged wire or solde...
步骤4Measure Resistance Turn the knob in the multimeter to set the test to Ohms/Resistance Connect the terminal 1 and 2 of the component Intake air temperature sensor to Multimeter positive and negative The set value at ignition on and engine cold is 1.3KOhms ...
The cable core checking and setting network circuit is composed of resistors with different integral K values and respectively supplies the resistance value consistent with the socket serial number to each cable core socket for checking the cable cores. One end of the cable core is sheathed with ...

Those of you who use radiation thermometers already know that bare metal is difficult to measure with radiation thermometry, because the emissivity is so low. See below for a demo that Frank Liebmann set up. He took a flat plate infrared calibrator and left one s...
Resistance measurement:passed! And there you have it, not bad at all considering the price! I do have to mention that the current measurement was fluctuating a bit with the backlight on (it’s probably a good idea to replace the battery). ...
Use the multimeter to measure the coil resistance between the two connection pins of the idle speed actuator. Reference value = approx. 10 ohms (observe manufacturer's specifications). 3 Checking the coil for winding short circuit Check the coil for a winding short circuit between the two connec...
