Frequently Asked Questions - PLMT15 Pyle

How do I turn on the Pyle PLMT15 luxmeter?

Press the POWER button once. The LCD will light up. To turn off, press and hold the same button for about 2 seconds.

What is the measuring range of the PLMT15?

It measures from 0.1 to 50,000 Lux (or 0.01 to 5,000 Foot-Candles). The auto-ranging function selects the appropriate scale.

How do I switch between Lux and Foot-Candle units?

Press the UNIT button to toggle between Lux (Lx) and Foot-Candle (Fc). The display will show the active unit.

What does the 'HOLD' button do?

The HOLD button freezes the current reading on the display. Press it again to release and resume live measurement.

How do I replace the battery?

Open the battery compartment on the back with a screwdriver. Remove the old 9V battery and insert a new one, observing polarity. Close the cover and tighten the screw.

Is the PLMT15 calibrated out of the box?

Yes, it is factory calibrated. For precise measurements, it is recommended to recalibrate annually using a standard light source or return to manufacturer.

Can I measure both fluorescent and LED light?

Yes, the sensor is designed for all common light sources including fluorescent, LED, incandescent, and natural daylight. Accuracy may vary slightly for some LEDs; refer to manual.

What does the 'PEAK' button do?

PEAK captures the maximum reading over time. Press once to activate peak hold; the display will show the highest recorded value. Press again to reset.

How do I clean the light sensor?

Use a soft, lint-free cloth slightly dampened with water or mild detergent. Gently wipe the sensor and housing. Do not use abrasive cleaners or immerse in water.

What should I do if the display shows 'LOBAT'?

LOBAT indicates low battery. Replace the 9V battery immediately to maintain accuracy. The meter may still function but readings could be unreliable.

(3) Take off photo sensor cover and put the sensor facing the light source.
(4) Get reading from display.
(5) If only the first digit shows 1, it means overflow, select higher range.
(6) When using the 20,000 Lux range, the measured value is equal to the reading X10.
(7) You can push "HOLD" key to stop the measurement and read the data, pushing the "HOLD" function and meter is back to measuring mode.
(8) After the measurement is done, turn off the power and put the photo sensor cover back.

4. Battery replacement

• when battery runs out of power, the display shows “☐” sign, you should change battery now.
• open the cover of battery chamber at the back of meter, take out the old battery and put a new 9V battery in.
