1scale Owner's Manual 

Low Batteries, bad battery connections & Faulty AC Adaptors are the #1 cause of scale malfunction 
and inaccuracy

! We test all of our scale returns from consumers. Fully 60% of consumer returns are 

battery related problems. This sounds silly but it's true! A scale will perform slowly, or read inaccurately 
when it has low batteries. Please replace the batteries often (and only use good quality batteries). We 
include good quality batteries with all of our scales but batteries can run low in storage. If your scale 
simply won't turn on while on Battery power, this is often caused by loose battery connections. Battery 
prongs (terminals) are made of metal. They must be making good contact with your batteries in order 
for the scale to power on. You can use a paperclip to slightly bend the battery prongs to make them 
have a better connection. Also some poorly designed batteries have recessed or partially obstructed 
battery terminals. This may cause your prongs to be touching the plastic housing of the battery instead 
of the metal battery terminal. A Faulty AC adaptor can cause your scale to act unstable with numbers 
"jumping" all around. Please test your scale with a good set of batteries (instead of the AC adaptor) to 
determine if perhaps the AC adaptor is faulty.
