A multimeter is the best tool for testing the output of your phono cartridge. The steps are as follows:

  • Ensure the multimeter is connected to the power supply and the ground terminal of the cartridge.
  • Set your multimeter to measure DC voltage.
  • Touch one of the leads of the cartridge to one of the multimeter’s leads.
  • The other lead should be connected to the ground.
  • Read the voltage measurement on the multimeter display. If it’s within specs, congratulations!
  • Your cartridge is in good working condition and should produce accurate sound.

How to test cartridges with an oscilloscope

Ensure that you get the highest possible sound quality by testing your cartridges. Analyzing and viewing waveforms generated by electronics is possible with the use of an oscilloscope. Your device’s circuitry (Turntable cartridge) can be identified using an oscilloscope and repaired or modified as necessary using the oscilloscope. Additionally, turntable cartridges can be tested with an oscilloscope.

How to use an oscilloscope

Oscilloscopes can be very useful tools for testing turntable cartridges and other components. This article aims to teach you how to use an oscilloscope to test turntable cartridges.

Understanding how an oscilloscope works are the first step to effectively using one. Oscilloscopes have traces on various circuit boards covered with probes that move back and forth. On the screen, a signal is displayed when the probe moves over a particular trace.

The digital oscilloscope is the most commonly used type of oscilloscope. Waveforms (or graphs), time-stamps, and starting points are some features available in this type of scope. A voltage or current level can be seen using waveforms at specific points in time. You can track down where a problem occurs by using time stamps. Identifying the starting point of a problem can help you solve it faster.

Identify the type of oscilloscope you need before testing phonograph cartridges with it. As well as being useful for testing cartridges, a digital scope may also be useful for other purposes. Consider purchasing a cartridge tester if you need to test only a few cartridges.

How to test turntable cartridges with an oscilloscope

To test cartridges, an oscilloscope is needed to determine if they are working properly. There are a few different methods when testing a cartridge with an oscilloscope. Testing a cartridge can be done with a continuity meter by measuring the resistance between the cartridge’s lead and the probe. Higher resistance indicates more wear and tear on the cartridge. Measure the resistance between the cartridge’s leads and ground using an ohmmeter is another way to test a cartridge.

How do you test turntable cartridges correctly with a multimeter?

In order to ensure that cartridges are functional, a skilled technician is often required. If you follow a few simple steps, a multimeter can easily be used to test turntable cartridges.

Testing a turntable cartridge correctly with a multimeter

Using a multimeter properly to test a turntable cartridge ensures its longevity. A common way to test a turntable cartridge is to use an ohmmeter.

  •  This method involves removing the cartridge cover and measuring the resistance between the pins on either side.
  • A higher resistance cartridge is more likely to be worn out.
  • If the pins on the cartridge are dirty or corroded, this method may not give accurate readings.

Using an electromagnetic sensor is another method of testing a turntable cartridge. Using an electrical signal, this type of sensor detects metal in contact with metal. You can determine how worn out a cartridge is by measuring the time it takes for the signal to decay. However, this method can be inaccurate if the tested area contains metal pieces other than cartridges or if the contacts are clogged with dirt or moisture.

 What is on a multimeter screen when you are testing a turntable cartridge?

  • Using your multimeter to test a cartridge, you’ll see this on the screen:
  • On the screen, the voltage will be the first thing you see. 
  • Either 12 or 24 volts will be used. 
  • You will next see the resistance displayed on the screen. 
  • It is always expressed in decimal format and measured in ohms. 
  • Next, you will see the capacitance. This is measured in microfarads and is always represented in a decimal format. 
  • Lastly, you will see the inductance. This is measured in henries, and it is always represented in a decimal format as well.

 How do you use Ohm’sOhm’s law to calculate the resistance of a turntable cartridge?

To determine the resistance of a turntable cartridge, it’s helpful to use Ohm’s law. Ohm’s law states that voltage is equal to current multiplied by resistance. Before testing, the voltage and current flowing through the phono cartridge should be determined. The resistance of the turntable cartridge can be calculated using Ohms law.

 How to Test if a Phono Cartridge is Good or Bad?

 Any record player relies on phono cartridges, which are essential to its operation. The question is, how do you determine whether your cartridge is working or not? Audio equipment testing is usually considered exclusive to professional studios and audiophiles. You can still determine if your turntable cartridge is in good condition by performing a few simple tests.

When testing a phono cartridge, it’s crucial to know what to look for. Is your goal to ensure the cartridge is working properly, or are you trying to identify problems with it? The function test should always be performed first if you only have time for one test. It will determine if the cartridge is loading correctly and producing sound. Afterward, you can check the cartridge alignment tests if the function test failed.

Alignment Tests:

It may be time to look at cartridge alignment tests if the cartridge function test still fails. The stylus will be measured and aligned inside the cartridge during these tests. In the event of alignment issues, playback quality may be affected. To conduct these tests, you’ll need a flat surface on which to place

Parts of the Phono Cartridge

The two most common types of phono cartridges are: 

  • Moving Magnet
  • Moving Coil

Before you begin playing your turntable cartridge, you should know its type:

Moving Magnet Phono Cartridges:

Audio signals are moved around the platter by magnets in these cartridges. Their sound is clear and distortion-free. Turntables with high output levels and those looking for pure audio quality should use these cartridges.

Moving Coil Phono Cartridges:

An audio signal is moved along a platter using coils in these cartridges. They produce a warmer, more distortion-filled sound. Unfortunately, they are only compatible with Moving Coil Turntables. Capacitor phono players and moving magnet turntables do not work with them.

What to Do If Phono Cartridge is Bad

You can check if a bad phono cartridge is causing your audio problems by doing a few things. 

  • Turntables can be tested by playing a record you know is in good condition. 
  • A new cartridge may be the source of your problem if sound quality improves when you change it. Your phono cartridge is likely defective if the sound quality remains poor even with a high-quality record.
