Features
- This Digital Tachometer provides fast and accurate non-contact RPM and surface speed measurements of rotating objects.
- This tachometer uses CPU, photoelectrical, and junction laser techniques for one instrument combined PHOTO TACH (RPM & REV).
- Two test modes: rotate speed mode (unit: RPM) & count mode (unit: REV).
- Wide measure range and high resolution.
- High visible digital LCD and Backlight display.
- Built-in memory recalls Max, Min, and Last value stored.
Measuring Manual
Apply a reflective mark to the object being measured. Depress the "MEAS" button and align the visible light beam with the applied target. Verify that the monitor indicator lights when the target aligns with the beam. Then the current mode is the last time mode. If you need to change the mode, release the "MEAS" button and press the "MODE" button before the instrument auto power off (released the "MEAS" button, this instrument will auto power off in 10 sec). The mode will convert between "RPM" and "REV" (revolution). Select the mode you need, and depress the "MEAS" to start measuring.
Press the "MEM" button to read the Max, Min, and Last values from the last measurement.
Measuring Consideration
Reflective Mark
Cut and adhere tape provided into approximately 12mm (0.5") squares and 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.
- Shaft surface must be clean and smooth before applying reflective tape.
Very Low RPM Measurement
As it is easy to get high resolution and fast sampling time, if measuring very low RPM values, it is suggested to attach more "REFLECTIVE MARKS" averagely. Then divide the reading shown by the number of "REFLECTIVE MARKS" to get the real RPM.
