Frequently Asked Questions - EV-520 Orava

How do I change the battery in my Orava EV-520 scale?

Open the battery compartment on the bottom of the scale. Remove the old CR2032 battery and insert a new one with the positive side up. Close the compartment securely.

How should I clean the scale?

Wipe the tempered glass platform with a soft, damp cloth. Do not use chemical or abrasive cleaners, and never immerse the scale in water.

What does 'OL' mean on the display?

'OL' stands for overload. The weight exceeds the maximum capacity of 150 kg (330 lb). Remove the weight immediately to avoid damage.

Why do I get different readings each time I step on?

Ensure the scale is on a hard, level surface. Stand still and center your weight evenly. Variations can also occur if the battery is low or if the scale is moved between weighings.

How do I switch between kg, lb, and st?

Look for a unit button on the back or front of the scale. Press it to cycle through kg, lb, and st. Refer to the manual for exact location.

What is the maximum weight for this scale?

The maximum capacity is 150 kg (330 lb). Exceeding this may cause permanent damage.

Can I use the scale on a carpet?

No, for accurate readings place the scale on a hard, flat surface like tile or hardwood. Carpet can lead to unstable measurements.

How do I know when the battery is low?

When the battery is low, the display will show 'LO'. Replace the CR2032 battery promptly.

Does the scale have an auto-off feature?

Yes, the scale automatically turns off after 10 seconds of inactivity to conserve battery life.

How accurate is the Orava EV-520 scale?
