How do I turn on the Pyle PLMT12 lux meter?

Press the power button located on the side of the device. The LCD screen will light up. If the display is dim, replace the 9V battery.

What is the measurement range of the PLMT12?

The PLMT12 measures illuminance from 0 to 200,000 Lux, suitable for dim indoor settings to bright outdoor conditions.

How do I change the measurement unit?

The PLMT12 displays in Lux only. To convert to foot-candles, divide Lux by 10.764.

How accurate is the PLMT12?

The accuracy is typically ±3% of the reading, with a resolution of 1 Lux.

Does the PLMT12 have a backlight?

Yes, the LCD has a backlight for easy reading in low-light conditions. Press the backlight button to toggle.

How do I use the data hold function?

Press the 'Hold' button to freeze the current reading on the display. Press it again to release and continue measuring.

What type of battery does the PLMT12 use?

It uses a standard 9V battery. To replace, open the battery compartment on the back, connect the new battery, and close the cover.

Can the PLMT12 measure light in different angles?

The sensor has a cosine-corrected head for accurate measurement at various angles, but it is designed for perpendicular incidence.

How do I clean the sensor?

Gently wipe the sensor lens with a soft, dry cloth. Avoid solvents or abrasive materials to prevent damage.

(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.
