INSTRUCTIONS FOR USE
1. Before using your gage, calibration must be checked. Secure She 5" Calibration Gage to a bench
using the holes provided, or, clamp in a soft-jaw vice. Turn on the display and set to Inches by
depressing the "in/mm" as required. Slide the display and movable arm to the leg until it contacts the
Stop Screw. Depress the ZERO button. Open the aims and set the pointed tips (Anvils) of the arms onto
the gaging surfaces of the Calibration Gage. The display should now read 5.QQQ" */-.010*. Due to the
design of the Wheels-on Drum Gage, with extended arm length necessary to clear axle hardware, it may
be helpful to take several readings in a row to develop the appropriate feel. When repeated readings
agree to less than •*•-/- .010? accuracy has been achieved. If the display does not read 5.QOQ" */- .010",
please refer to step 7 below for calibration adjustment
\. Select inch or millimeter measurement by depressing the button labeled "in
depressed at any Sme to convert measurements.
3. With scored surfaces, place the gage in the drum with the fixed ann Anvil held against one side, and
bring the movable arm Anvil into contact with the drum directly across, at the point of greatest diameter.
In this manner, measurements may easily be made o? the depths of the scores with the pointed anvils.
4. Unscored surfaces are measured in the same manner except that the anvils must be kept parallel to
the drum mounting face within 1/8" to assure an accurate reading. This is most quickly done by
measuring the brake drum at its furthest depth using the ends of the amis as depth stops
5. If the digital readout indicates a measurement approaching the limit over standard, the brake drum
should be pulled and measured in a more controlled environment A reading greater than the limit over
standard disqualifies the drum from further safe use. It should be replaced with a new brake drum which
meets the original equipment manufacturer's specifications.
6. To measure score depth only, measure the drum diameter hi a dear unscored area, press the ZERO
button, measure the drum diameter rn the score, then divide the resulting number by 2. This is the scope
depth.
