Frequently Asked Questions - P50 Prexiso

How do I turn on the Prexiso P50 rangefinder?

Press and hold the ON/OFF button for 2 seconds to power on. Press again to turn off.

How do I switch measurement units?

Press the Units button repeatedly to cycle through meters (m), feet (ft), inches (in), and feet+inches.

How do I measure area or volume?

Press the 1x button for area (measures length and width) or 2x for volume (measures length, width, and height). Point the laser and press the measure button for each dimension.

What is the Pythagoras function used for?

The Pythagoras 2-point mode calculates an indirect distance (e.g., height) using two measurements. Press the 3x button to enter this mode.

How do I replace the batteries?

Open the battery compartment at the bottom, insert two AAA batteries observing polarity (+/-), and close the cover.

Is the laser safe for eyes?

The device uses a Class 2 laser (< 1 mW, 635 nm). Avoid direct eye exposure. Do not stare into the beam.

What is the maximum measurement distance?

The Prexiso P50 can measure distances up to 50 meters (164 feet) under ideal conditions.

How accurate is the rangefinder?

Typical accuracy is ±2 mm over the entire range. Accuracy may degrade in low light or poor target reflectivity.

What should I do if the device doesn't turn on?

Check if batteries are installed correctly (polarity) and have sufficient charge. Replace with fresh batteries if needed. Ensure the contacts are clean.

How do I clean the lens?

Use a soft, dry cloth to gently wipe the lens. Avoid solvents or abrasive materials. Do not immerse in water.
