Turn on the scale as described above, place the “tare item” on the platform, press the
“TARE” button(which is marked as a “Z” on the side of the scale) to zero out the display,
when “0.0” appears on the screen you may now place items on the scale to be weighed.
Once you are finished weighing, remove all objects from the scale, press the “TARE”
again to cancel the TARE FUNCTION.
After weighing an item, if the display does not read “0.0” press the ZERO/TARE button
to return to “0.0” and you are ready to weigh again.
Press the “CAL/MODE” button to change weighing modes on your scale. This scale has
4 weighing modes: g, oz, gn, dwt.
With the scale turned on and placed on a stable surface, press and hold the CAL/MODE
button. The display will show “CAL”, press and release CAL button again and “100.0”
will flash in the display, immediately place a total of 100g weight on the scale. The scale
will reset itself and will give you a PASS message. Calibration is complete.
The optimum operating temperature for the scale is 50-86° F/10-30°C. Rough handling of
the scale will damage the internal sensor; so you must avoid actions such as shaking or
dropping the scale. This is a sensitive piece of electronic equipment and will be affected
by things such as moisture, extreme temperature changes, magnetic fields, careless
handling and misuse.
The scale will automatically shut-off after 60 seconds of inactivity this is to help conserve
the battery power. We recommend good quality AAA batteries.
