Frequently Asked Questions - 40-8747 Cocraft

How do I change the battery in my Cocraft 40-8747 laser distance measurer?

Open the battery compartment on the back, remove the old batteries, and insert two new AAA alkaline batteries, observing correct polarity. Close the compartment securely.

What is the maximum measuring range of the 40-8747?

The device can measure distances from 0.05 to 40 meters (0.16 to 131 feet). For best accuracy, use a target plate for ranges above 10 m.

How accurate is the Cocraft 40-8747?

The accuracy is ± 2 mm (0.08 inches) under favorable conditions. Accuracy may decrease in bright sunlight or on poorly reflective surfaces.

Can I use the device outdoors?

Yes, but performance may be reduced in direct sunlight. The laser beam is more visible in low light. For ranges above 10 m, use the included target plate.

What units can the 40-8747 display?

The device can display measurements in meters, feet, and inches. Press the unit button to cycle between them.

How do I measure area or volume?

Press the function button to select area or volume mode. Measure the first side, then the second side (and third for volume). The device automatically calculates the result.

Why is my device not turning on?

Check that the batteries are installed correctly and have sufficient charge. Replace with fresh AAA batteries. If the problem persists, contact Cocraft support.

How do I clean the laser lens?

Use a soft, lint-free cloth lightly dampened with water or lens cleaner. Gently wipe the lens. Do not use abrasive materials or solvents.

What does the error message 'Err' mean?

'Err' indicates that the measurement could not be taken, often due to a weak laser return signal (e.g., too far, too bright, or reflective surface). Try measuring a closer, matte surface.

Is the laser safe for eyes?

The device uses a Class II laser (< 1 mW). Avoid direct eye exposure. Do not point the laser at people or animals. It is generally safe if used as directed.

C. Depth/height measurement

D. Step measurement

E. Differential measurement. The difference in size of two or more objects can be determined by zeroing the caliper on the correctly sized reference object.

Care and maintenance

• Wipe the entire measuring scale with a soft cloth. Do not use solvents to clean the caliper.
• Keep the caliper dry and clean.
  • Always turn the device off when it is not in use.
• Never measure surfaces that are conducting electrical current.
• Do not engrave the caliper with an electric engraver. This may damage the caliper.
• Changing the battery can cause the digits on the display to flicker. Remove the battery and wait 60 seconds before replacing it.

Changing the battery

When the display becomes weak the battery needs to be changed. Remove the screws on the back of the caliper, open the battery cover and replace the battery. The positive terminal (+) should face upward.
