Frequently Asked Questions - PLT26 Pyle

How do I use the Pyle PLT26 tachometer?

First, apply a reflective mark to the rotating object. Then press and hold the MEASURE button, aim the light beam at the reflective mark, and release the button when the reading stabilizes. The measurement results (Max, Min, Last) are automatically stored.

How do I apply the reflective tape?

Cut the adhesive tape into approx. 12mm (0.5 inch) squares and apply one square to a clean, smooth surface of the rotating shaft. Ensure the non-reflective area is larger than the reflective area. If the shaft is reflective, cover it with black tape or paint first.

What does the low battery symbol mean?

When the battery voltage drops below approx. 4V, the symbol '*' will appear on the display. This indicates you need to replace all four AAA batteries.

How to measure very low RPM values?

For low RPM, attach multiple reflective marks evenly spaced around the shaft. After measurement, divide the displayed reading by the number of marks to obtain the true RPM.

How do I recall stored Max, Min, and Last values?

Press the MEMORY button. The display will cycle through 'UP' for Max, 'DN' for Min, and 'LA' for Last value. Symbols indicate which value is shown.

What is the detecting distance of the laser and LED?

The LED beam works at 50-250 mm (2-10 inches), while the laser beam works at 50-500 mm (2-20 inches) from the reflective target.

What batteries does the PLT26 use and how to replace them?

It uses 4 x 1.5V AAA (UM-3) batteries. To replace, slide off the battery cover (3-6), remove old batteries, and insert new ones observing correct polarity.

Is there any safety precaution I should be aware of?

Yes, avoid pointing the laser beam into eyes or looking directly into the beam. It can cause injury to eyes. Keep away from children.

What is the measurement range and accuracy?

The range is 2.5 to 99,999 RPM. Accuracy is ±(0.05% + 1 digit). Resolution is 0.1 RPM for readings below 1000 RPM and 1 RPM above.

How to maintain the tachometer?

If not used for an extended period, remove the batteries to prevent leakage. Keep the housing clean and store in the provided carrying case.

USER MANUAL PLT26 Pyle

Your purchase of this DIGITAL TACHOMETER marks a step forward for you in the field of precision measurement.

Although, this PHOTO TACHOMETER is a complex and delicate instrument, its ruggedness will allow many years of use if proper operating techniques are developed. Please read the following instructions carefully and always keep this manual within easy reach.

WARNING!

TO AVOID INJURIES TO ANIMAL OR HUMAN EYES, PLEASE DO NOT POINT THE LASER BEAM IN EYES OR LOOK DIRECTLY INTO BEAM.

1. FEATURES

* Measuring RPM is safe & accurate without attachment to object.

* Wide measuring range & high resolution.

* Digital display gives exact RPM with no guessing or errors.

* Used the exclusive MICRO-COMPUTER LS-I circuit and crystal time base to offer the high accuracy measurement & fast measuring time.

* The last value/max, value/min, value will be automatically stored in memory and can be recalled anytime.

* The use of durable, long-lasting components, including a strong, light weight ABS-plastic housing assures maintenance free performance for many years. The housing has been carefully shaped to fit comfortably in either hand.

2. MEASURING CONSIDERATION

2-1 REFLECTIVE MARK

Cut and peel adhesive tape provided into approx.12mm (0.5") squares and apply one square to each rotation shaft.

a. The non-reflective area must always be greater than the reflective area.

b. If the shaft is normally reflective, it must be covered with black tape or black paint before attaching reflective tape.

c. Shaft surface must be clean and smooth before applying reflective tape.

2-2 VERY LOW RPM MEASUREMENT

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.

2-3 BATTERY REMOVAL

If the instrument is not be used for any extended period, remove batteries.

3. MEMORY

3-1 A readout (the last value, max value, min value) obtained immediately before turning off the MEASURE BUTTON is automatically memorized. For example, please reference following fig.1.

3-2 The Memorized value can be displayed on the indicator by

pressing the memory button. The symbol, "UP" represents the Max. Value and "DN" represents the Min Value; "LA", the last Value."

4. BATTERY REPLACEMENT

(1) When it is necessary to replace the battery (battery voltage less than approx.4v),
“-+”will appear on the display.
(2) Slide the battery cover (3-6) away from the instrument and remove the battery.
(3) Install the batteries 1.5V AAA (UM-3) correctly into the case.

4) MEASURING PROCEDURE

Apply a reflective mark to the object being measured. Depress

the MEASURE BUTTON (3-4) and align the visible light beam

(3-2) with the applied target. Verify that the MONITOR

INDICATOR lights when the target aligns with the beam (about

1 to 2 seconds.)

5) Photo rotational speed

A. Apply a reflective mark to the object being measured slide the function switch to "RPM photo" position.
B. Install the batteries first, then depress the measuring button and align the visible light beam with the applied target.
C. Release the measuring button when the display reading stabilizes. The Max value, MIN value and the last value of measurement results all store automatically in the indicator.
D. Press "MEM". It will show the MAX value, the MIN Value and the last value.
E. The measurement is finished.
