Frequently Asked Questions - PST43 Pyle

How do I measure RPM with the Pyle PST43?

Apply a reflective mark to the rotating object. Depress the operation button and align the laser beam with the mark. Ensure the target indicator lights each revolution. Release the button after about 2 seconds when the reading stabilizes.

What should I do if the RPM reading seems too low?

For very low RPM, attach multiple reflective marks evenly spaced. Divide the displayed reading by the number of marks to get the actual RPM.

How does the memory recall function work?

After measurement, press the memory call button repeatedly: first shows the last value (symbol LA), then the maximum (symbol UP), then the minimum (symbol DN).

What does the low battery indicator look like?

When the battery voltage drops below approximately 4.5V, the LCD displays LO. Replace batteries soon, though accurate measurements may continue for a few hours.

How to replace the batteries?

Open the battery cover on the back. Remove old batteries and insert four new 1.5V AA (UM-3) batteries. Close the cover securely.

Can I measure reflective surfaces that are not shiny?

The tachometer requires a reflective mark (included) to be applied to the object. Non-reflective surfaces will not reflect the laser beam properly.

What is the maximum distance for measurement?

The manual does not specify a maximum distance, but the laser beam works best within a few inches to a few feet. Ensure the target indicator lights reliably.

Is the laser safe for eyes?

No. The device uses a Class II laser. Never point the laser at eyes or look directly into the beam to avoid injury.

How to clean the tachometer?

Use a soft, dry cloth to clean the exterior. Do not use liquids or solvents as they may damage the housing.

What accessories are included in the box?

The package includes the tachometer, a carrying case, a roll of reflective tape marks (600 mm), and the operation manual.

4. MEASURING PROCEDURE

Apply a reflecting mark to the object being measured.

Depress the "Operation button" (3-5 Fig 1) and align the visible "photo signal Light beam" (3-2 fig1) with the applied target. Verify that the "Target indicator" (3-3 fig 1) lights when the target passes through the light beam. Release the "operation button" when the reading stabilizes (about 2 seconds).

Consideration:

If measuring very low RPM values, attach more

"REFLECTIVE MARKS" evenly spaced apart from each other. Then divide the reading shown by the number of

"REFLECTIVE MARKS" to get the real RPM.

5. MEMORY CALL BUTTON OPERATION

1) The minimum, maximum and the last (final) readings are automatically stored during measurement. These values can be recalled anytime by pressing the "Memory call button" (3-6 fig1).

Fig. 2

2) To recall the stored value, follow these procedures: Release the "operation button" (3-5 fig 1) first.
a) Press the "memory call button" (3-6 fig1) once to display the last reading. The symbol "LA" will appear on the display.
b) Press the "memory call button"(3-6 fig1) once again to display the maximum value. The symbol "UP" will appear on the display.
c) Press the "memory call button"(3-6 fig1) once more to display the maximum value. The symbol "DN" will appear on the display.

6. BATTERY REPLACEMENT

1) When "LO" appears on the LCD display, it indicates a battery output of approximately less than 4.5v. It is recommended to replace the battery; however in-spec measurement may still be made for several hours after low battery indicator appears before the instrument becomes inaccurate.
2) Open the "battery cover" (3-7 Fig. 1). Inside the battery compartment, replace with new batteries and reinstate the cover.
