PST30

OPERATION

MANUAL

CAUTION

● Do not look directly at strobe or shine at others. Light

pulses at a frequency greater than 5 Hz may cause

photosensitive epilepsy in some individuals if directly

viewed.

●

Avoid Injury, do not point the light beam of the

instrument or have it reflected into the eyes of people

or animals.

●

feature of the instrument is to make moving objects

appear to be stationary. Precaution should therefore

be taken to ensure that there is no physical contact

made with objects being viewed.

● Do not leave the device close to water or any other

liquid to avoid damage.

● If not using this instrument for extended periods of

time, remove the batteries to prevent potential battery

leakage which may damage the product.

● This instrument contains no user serviceable parts

and should not be opened by the user.

● Repair or service should be done by a qualified

technician only.

● Only use a dry cloth to clean the plastic case.

Do you have a question about the Pyle PST30 and is the answer not in the manual?

The PYLE PST30 Digital Stroboscope Tachometer is a microprocessor-controlled device designed for inspecting and measuring the speed of moving objects. It offers high accuracy and a digital readout, making it suitable for industrial maintenance, production, quality control, laboratories, and educational demonstrations of strobe action.

Function Description:

The primary function of the PST30 is to make moving objects appear stationary or in slow motion by synchronizing its flash rate with the object's movement. This allows for detailed inspection of gears, fans, centrifuges, pumps, motors, and other equipment. It can also measure the speed of these objects in RPM (rounds per minute) or FPM (flashes per minute).

Important Technical Specifications:

Measuring Range: 60 to 19999 RPM / FPM
Accuracy: 0.05%
Resolution:
- Less than 1000 RPM: 0.1 RPM/FPM
- More than 1000 RPM: 1 RPM/FPM
Display: 19999 count digital display
Power: 4 x 1.5V R6P.AA.UM-3 batteries
Battery Consumption: Approximately 60mA
Dimensions: 8.03” (204mm) x 2.87” (73mm) x 1.38” (35mm)
Weight: Approximately 200g

Usage Features:

The device features a user-friendly interface with an LCD display and several control buttons:

Power ON/OFF: Press and hold the power switch to turn the unit on. The display will show the initial factory default flash rate of 1200 RPM.
Coarse/Fine Tuning: A dedicated button allows switching between Coarse and Fine adjustment modes for the flash rate. In Fine adjustment mode, a "FINE" icon appears on the display.
Flash Rate Adjustment (Manual):
- In COARSE mode, pressing "up" or "down" buttons adjusts the flash value by 10 RPM (for ranges > 1000 RPM) or 1 RPM (for ranges < 1000 RPM).
- In FINE mode, pressing "up" or "down" buttons adjusts the flash value by 1 RPM (for ranges > 1000 RPM) or 0.1 RPM (for ranges < 1000 RPM).
Flash Rate Adjustment (Auto): Pressing "up" or "down" buttons for more than two seconds enters Auto-adjust Mode.
- In COARSE mode, the value adjusts every 0.2 seconds by 10 RPM (for ranges > 1000 RPM) or 1 RPM (for ranges < 1000 RPM).
- In FINE mode, the value adjusts every 0.2 seconds by 1 RPM (for ranges > 1000 RPM) or 0.1 RPM (for ranges < 1000 RPM).
- The device automatically stops adjusting when the maximum (19999 RPM) or minimum (60 RPM) rate is reached.
TACH Measuring: To find the true speed, adjust the flash rate until the object appears stationary. If multiple stationary images (harmonics like 2:1, 3:1, etc.) appear, turn the dial until two images appear (doubling the actual speed), then lower the flashing rate until a single, stationary image appears. This represents the actual true speed.
Motion Analysis: After determining the actual speed, slowly adjust the dial up or down to create a slow-motion effect, enabling complete inspection of the moving object.
Display Indicators: The LCD shows the measuring data, RPM unit symbol, an indicator for measuring, and a low battery indicator symbol.
Backlight Switch: A dedicated switch for the display backlight.

Maintenance Features:

Battery Replacement: Open the battery compartment cover on the back of the unit to replace the 4 x 1.5V AA batteries. Ensure correct polarity.
Cleaning: Only use a dry cloth to clean the plastic case.
User Serviceability: The instrument contains no user-serviceable parts and should not be opened by the user. Repairs or service should only be performed by a qualified technician.
Storage: If not using the instrument for extended periods, remove the batteries to prevent potential battery leakage and product damage.
Environmental Protection: Do not leave the device near water or any other liquid to avoid damage.

Safety Precautions:

Do not point the light beam directly into the eyes of people or animals, nor allow it to be reflected into their eyes, to avoid injury.
Be aware that the instrument makes moving objects appear stationary. Exercise caution to avoid physical contact with objects being viewed.
