Operating Instructions Applying Reflective Marking Tape 1. 2. 3. 4. 5. Cut and peel the adhesive tape provided into approximately 0.5" (12mm) squares. Apply one square to each rotation shaft. The non-reflective area must always be greater than the reflective area. If the shaft is normally reflective, it must be covered with black tape or black paint before attaching reflective tape. The shaft surface must be clean and smooth before applying the reflective tape. Photo Measurements 1. 2. 3.
Surface Speed Measurements 1. 2. 3. 4. Slide the function switch to the "m/min contact" position. Install the surface wheel adapter on the instrument. Press the Measure button while lightly pressing the surface wheel against the surface being measured. Release the Measure button when the display reading stabilizes (approx. 2 seconds). NOTE: If the inside part of the wheel is used (as shown in the picture), measurements are required to be multiplied by 0.9 for an accurate measurement.
To display these values, follow the steps below: 1. Press and hold the MEM button once. A value is displayed followed by the "UP" symbol, which represents the maximum value. 2. Release the MEM button. 3. Press and hold the MEM button again. A second value is displayed followed by the "dn" symbol, which represents the minimum value. 4. Release the MEM button. 5. Press and hold the MEM button again. A third value is displayed followed by the "LA" symbol, which represents the last value. 6.
Accessing Stored Measurements The meter has the capability of storing up to 64 values during a single measuring period. In order to recall these values, follow the steps below: 1. Press the MEM button four times and hold it down. 2. The meter will begin to countdown from 20 to 1 RPM indicating it is compiling the stored values. 3. Once the countdown is completed, a total of the values stored will display as "An XX", whereas XX will be the number of stored measurements. 4.
