• Accuracy: [±6 gr (0.16 oz) / ±0.01 lb / ±0.01 Kg] or 0.1% of reading whichever is greater
• Resolution: 0.05 lb/0.4 oz (0.01 kg)
• Automatic shut- off: (after 3 hrs)
• Operating temperature: 32˚F to 120˚F (0˚C to 49˚C)

REPLACING THE BATTERY
Replace 9V battery when a low-battery symbol prompts on LCD. DO NOT OPERATE with a low battery.
STATIC DISCHARGE: Climates in some parts of the
world are conducive to creating static electric build up
(ESD). Your scale has been designed to eliminate the
damaging effects of ESD. In some extreme cases, ESD
will be apparent on your scale by a lack of response or
an inability to turn off the unit. In the rare case that
this occurs, simply disconnect the battery, wait 1
minute and reconnect the battery. The scale will
“reboot” itself and operate normally once the unit is
turned on.
