A Professional tracking force gauge designed for vinyl record purist's interested in more precise measurement of vertical tracking force (VTF). For accurate VTF measurement, the stylus tip should be at the same vertical position as the record surface - that is, at "record level". With Riverstone's professional VTF gauge, vertical tracking force is measured approx. 2 mm to 3 mm from the surface of a turntable mat or platter - which is the height of a stylus tip resting on an LP record (LP's have a thickness range of 1.9 mm to 2.9 mm). And, with this VTF gauge, there is no need to remove your platter mat - the gauge arm places the stylus tip at the correct height. Less expensive gauges typically have a stylus tip measurement distance between 6 and 10 mm - which leads to errors in measurement of tracking force. To reduce interaction with magnets in MM and MC cartridges, the VTF gauge is manufactured from durable plastic and the detachable cantilevered extension arm is made from a non-ferromagnetic grade of stainless steel. Two calibration masses (5g and 20g) are included for re-calibration (1-minute procedure). With larger calibration masses (not supplied) the gauge can be re-calibrated for use up to 100 g. A polymer pad on the measuring platform protects the stylus tip and allows accurately centering the stylus on the measuring platform. The LED display (green) is bright and easy to read. A very detailed instruction manual is provided. Overall dimensions: 52 mm (W) x 91 mm (L) x 12.0 mm (H); height dimension is with cover removed. PLEASE NOTE: Although no tools are required, installation of the record-level extension arm requires a bit of technical savvy. A tin storage box is included to protect the VTF gauge when not in use. All Riverstone Audio Tracking Force Gauges are covered by a full TWO-YEAR WARRANTY. ***Requires one Alkaline AAA battery (sorry, battery NOT included)***
- A Professional digital stylus tracking force scale designed for vinyl record purist's interested in precise measurement of vertical tracking force (VTF) at the correct vertical tracking angle (VTA). When used with the detachable cantilevered extension arm, the scale closely approximates the vertical position of the stylus on the surface of a vinyl record when it is playing on a turntable - providing accurate “record-level” measurements.
- For optimal accuracy, tracking force should be measured at the same vertical position as the record surface. With Riverstone's VTF's patented design (US Patent D878232), stylus tracking force is measured 2 mm - 3 mm from the surface of a turntable mat - the height of a stylus tip resting on an LP record (LP's have a thickness range of 1.9 - 2.9 mm). With less expensive devices, the measurement distance is typically 6 mm to 9 mm.
- Precision strain-gauge sensor provides 0.005 g measurement resolution and accurate measurements. To ensure accurate VTF measurement, our VTF scales undergo a rigorous multi-point calibration procedure to verify the linearity, repeatability and accuracy of the VTF measurement. We have confidence in our products and provide TWO calibration masses (5g and 20g) to so that you can verify the readings at any time and also allow for future re-calibration if needed.
- Manufactured using non-magnetic materials to minimize interactions with the MM and MC cartridges. The housing of the VTF scale is injection molded using a quailty ABS polymer. The cantilevered extension arm is machined from a verified non-ferromagnetic grade of stainless steel; the locking screw for the extension arm is machined from aluminum and brass. A polymer pad protects the stylus tip during measurement and allows centering of the stylus on the measurement platform.
- Riverstone Audio VTF scales are covered by our no-nonsense THREE-YEAR WARRANTY. Two levels of battery protection are used: auto-turnoff of the display and auto powering off of the circuit after 60 to 120 seconds of inactivity. A detailed instruction manual (in English) is provided. Includes a tin storage box to protect the VTF scale when not in use. PLEASE NOTE: *****Requires one AAA ALKALINE battery (SORRY, BATTERY IS NOT INCLUDED)*****.
