FEATURES
- Intelligent, microprocessor circuit design, high accuracy, wide range, digital readout.
- One instrument include two functions of " Digital Photo Tachometer " & " Digital Stroboscope "
- Digital Stroboscope :
Wide setting range from 100 RPM to 100,000 RPM, digital display with high accuracy. Modern solid state high visible orange light, long life, almost maintenance free. It is ideal for inspecting and measuring the speed of moving gears, fans, centrifuges, pumps, motors and other equipment used in general industrial maintenance, production, quality control, laboratories and as well as for schools and colleges for demonstrating strobe action.
- Digital Photo Tachometer :
No contact RPM measurement, wide measuring range from 0.5 to 100,000 RPM. 0.1 RPM resolution for the measured value < 1000 RPM. The last value, max., value, min. value can be stored into the memory automatically & be obtained by pressing " Memory Call Button ". High
visible LCD display gives RPM reading exactly with no guessing or errors.
- The use of durable, long lasting components, including a strong, light weight ABS plastic housing. Cabinet has been carefully shaped to fit comfortable in either hand.

閃頻操作程序
OPERATIONS PROCEDURES ( STROBOSCOPE )
準備 (Preparation)
- Determine the range switch to " 1000 RPM " ," 10,000 RPM " or " 100,000 RPM " position.
檢查速度 (Checking Speed)
- When checking speed, care must be taken to insure that the strobe is flashing in unison (one to one) with the object being monitored. A Stroboscope will also stop motion at 2:1, 3:1, 4:1 et., this is normally referred to as harmonies. To be sure of unison, turn the dial until two images appear - this will double the actual speed. Then lower the flashing rate until a single and stationary image appears - this is the actual true speed.
檢查動作 (Checking Motion)
- For motion analysis, simply locate the actual speed as mentioned above and then turn the dial slowly up or down. This will give a slow motion effect allowing complete inspection.
