Two of the most important adjustments on any turntable are tracking force and anti-skate. Together, they determine how the stylus sits in the record groove, how cleanly it tracks the signal, and how much wear it imparts to both the stylus and the record. Getting these settings right is not complicated, but it requires a little patience and the right tools.

What Is Tracking Force?

Tracking force, also called vertical tracking force or VTF, is the downward pressure the stylus exerts on the record groove, measured in grams. Every cartridge has a recommended tracking force range specified by the manufacturer, typically something like 1.8 to 2.2 grams with an optimal point of 2.0 grams.

Setting tracking force too light causes the stylus to skip, chatter, or mistrack in loud passages. The cartridge cannot maintain proper contact with the groove walls, which distorts the signal and can cause momentary skipping that physically damages the groove. Setting tracking force too heavy increases groove wear over many plays and can stress the cantilever.

Within the recommended range, erring slightly toward the heavier end often produces better tracking, particularly in the inner grooves where the recorded velocity is higher. The light end of the range is not necessarily better despite what some audiophile lore suggests.

Measuring Tracking Force

The most accurate way to set tracking force is with a dedicated stylus force gauge. Digital scales accurate to 0.01 grams are available for $15 to $40 and are a worthwhile investment for any vinyl enthusiast. Place the gauge on the platter at stylus height, lower the tonearm carefully onto the gauge platform, and read the measurement.

Alternatively, some turntables have a calibrated tracking force dial on the counterweight. These are reasonably accurate but should be verified with a scale if you want to be precise.

Setting the Counterweight

Most tonearms use a threaded counterweight at the rear of the arm to balance and adjust tracking force. First, balance the tonearm to zero tracking force by rotating the counterweight until the arm floats level without touching the platter. Do this with the cartridge installed but the anti-skate set to zero and the tonearm clip removed.

Once balanced, rotate only the outer scale ring (not the body of the counterweight) to align the zero mark with the indicator. Then rotate the entire counterweight body, including the scale, toward the front of the arm to add downforce. Each number on the scale represents one gram of tracking force. Rotate until the indicator aligns with your target tracking force value.

Verify the actual force with your scale and fine-adjust as needed.

What Is Anti-Skate?

As the tonearm tracks from the outer groove to the inner groove, a skating force pulls the arm toward the center of the record. This lateral force occurs because the tonearm is not perfectly tangential to the groove. Anti-skate applies a counterbalancing outward force to keep the stylus sitting evenly between the two groove walls. Without it, the stylus presses harder against the inner groove wall, which causes distortion and uneven stylus wear.

Setting Anti-Skate

The standard starting point is to set anti-skate to the same numeric value as your tracking force. If tracking force is 2.0 grams, start anti-skate at 2.0 as well. This is a guideline, not a precise formula: different cartridge shapes and stylus profiles interact with the groove differently.

To fine-tune anti-skate, play a test record with a blank or nearly blank groove (or a test LP with dedicated anti-skate tracks) and listen for balanced distortion on both channels. If sibilance or distortion is worse on the right channel, reduce anti-skate slightly. If worse on the left, increase it. Most setups do well with anti-skate set between 80 and 100 percent of the tracking force value.

Once both settings are dialed in, your cartridge will track reliably, distort less, and be kinder to both your records and the stylus over time.
