Operating Instructions

Important! Do not bump or shock the tool when applying it to any work piece. Rough treatment may damage the highly sensitive mechanism.

Note: There are many applications for the Digital Indicator. The following is one example of how this product can be used: testing brake rotors for true.

• Install battery by removing screw(s) and opening battery compartment. Install battery in correct polarity, close compartment and replace screw(s).
• Clean off all brake components with brake parts cleaner before testing.
• Push the "OFF/ON" Button to turn the meter "ON".
• Clamp the Indicator (clamp sold separately) in place so that only the needle contacts the brake rotor. Push the Zero Button to set the dial to zero. Do not clamp the Indicator too forcefully against the object being measured. There must be room for the needle to move in and out while under pressure.
• Spin the rotor by hand to see if it is true. As the rotor spins, the needle will move in and out. The display will indicate the amount of difference in true; the measurements which are above and below the baseline you established at the beginning.
• Press the inch/mm Button to have the Indicator display switch between inches or millimeters.
