Thank you for purchasing US-JEWELRY-PRO digital pocket scale.

Please read all operation instructions carefully before use.

Scales are precision instruments and should always be handled
with proper care. To ensure years of reliable service, keep these
simple tips in mind:

• Do not exceed the scales maximum capacity. Overloading your scale

can permanently damage it!

• Avoid exposure to extreme heat or cold. Scales perform best at normal

room temperature. If temperatures have changed dramatically,

recalibration may be necessary.

• Allow your scale to warm up for 30-60 seconds before performing

calibration (if available).

• Store your scale in a clean, dry location. Dust, dirt, and moisture can

accumulate on the weighing sensors and electronics causing inaccuracy

or malfunction.

• Avoid using you scale in close proximity to strong radio wave emitting

devices such as computers, cash registers, and cordless phones.

• Always weigh on a flat level surface, free from vibrations and drafts.

The corner of a room is usually the most stable.

• Gently apply all items to be weighed. Do not drop items onto the

weighing platform.

Avoid dropping your scale. The warranty does not cover damage due to

rough treatment or overload.

V-CALIBRATION

When to calibrate:
Calibration may be required when it is initially installed If the mini scale is
moved to a substantial distance. This is necessary because the weight of a mass
in one location is not necessarily the same in another location. Also, with time
and use, mechanical deviations may occur.

for 1 minute.

2. Enter calibration mode:

- Press [ON/OFF], while keeping pressing [UNIT], the display will
