Frequently Asked Questions - 390 JATA
How do I switch between units (g, kg, oz, lb:oz)?
Press the UNIT button to cycle through available units. The selected unit will appear on the LCD display. The scale remembers the last unit used when turned off.
How do I use the tare function?
Place an empty container on the platform, wait for the reading to stabilise, then press TARE. The display will zero out, allowing you to weigh only the contents. This feature can be used repeatedly.
How do I change the batteries?
Open the battery compartment on the underside. Remove old batteries and insert new AAA batteries, respecting polarity (+/-). Close the compartment securely.
How do I clean the scale safely?
Wipe the platform and casing with a soft, slightly damp cloth. Never submerge the scale in water or use abrasive cleaners. Dry thoroughly before storing.
Why does the scale display 'Err' or 'O-Ld'?
'Err' or 'O-Ld' indicates the scale is overloaded. Remove the item immediately to avoid damaging the sensor. The scale typically has a maximum capacity of 5kg. If no overload, try resetting by removing batteries for a minute.
Why does the scale not turn on?
Check that the batteries are installed correctly and have sufficient charge. Replace them if necessary. Also ensure the scale is on a flat surface, as some models require being on a stable platform to turn on via pressure.
How accurate is the scale?
The Jata 390 offers a graduation of 1 g or 0.05 oz, providing accurate measurements for most household cooking and baking needs. For best results, use it on a level surface and avoid air currents.
Can I use the scale for commercial purposes?
This scale is designed for domestic use. For commercial applications, you would require a scale approved for trade (legal-for-trade) with relevant certifications.
What is the maximum weight I can measure?
The maximum capacity is 5 kg (11 lb), displayed in g, oz and lb:oz. Exceeding this value will trigger an overload warning and could damage the sensor.
How should I store the scale?
Store the scale in a clean, dry place. Avoid extreme temperatures and humidity. If not used for a long time, remove the batteries to prevent leakage.
