SFG-2 -- Stylus Force Gauge
General Description
The Shure Model SFG-2 Stylus Tracking Force Gauge is a highly accurate beam balance that is designed for
measuring stylus tracking forces from 0.5 to 3.0 grams in .05 gram increments. Its rolling bearing pin pivots are en
gineered for minimal friction. Each SFG-2 Tracking Force Gauge is factory calibrated.
Instructions for Use
1. Ensure that your turntable is on a level surface and that its platter is level.
2. Place the SFG-2 on your turntable platter so that the turntable spindle fits into the vee notch of the SFG-2, as
pictured above. For better stability, you may instead place the SFG-2 on top of an LP record. Temporarily set
anti-skating controls on your turntable or tonearm to zero.
3. Position the sliding weight on the SFG2 at the tracking force that you would like to set for your tonearm (mea
sured in grams). For forces over 1.50 grams, set the weight to half the desired force.
4. Carefully lower the tonearm and cartridge so that the stylus rests in one of the grooves on the lever arm. If you
dialed in the force desired, use the groove labelled “TIMES 1"; If you dialed in half the desired force, use the
“TIMES 2" groove, as illustrated below.
