1. INTRODUCTION
General and Safety Information
For use in dry environments only.
This product uses a NI-MH battery. Dispose of according to local laws and
regulations.
Read and understand all operating instructions before using this product. Keep
this manual for future reference.
Allow sufficient warm up time. Turn the scale on and allow up to 10 minutes for internal
components to stabilize before weighing.
Record the weight shortly after placing a load on the platter. Leaving loads in place for
extended periods may vary the load cell’s output signature and may result in a less
accurate reading.
Avoid extended exposure to extreme heat or cold. Optimum operation is at normal room
temperature. See operating temperature range in the specifications table. Allow the scale
to acclimate to room temperature before using.
When storing the scale for extended periods, the battery must be charged every 90 days
to avoid premature performance degradation. Over time, the operating time per charge
will degrade. If the operating time is no longer acceptable even after recharging, the
battery must be replaced. Contact Global Industrial for additional information.
Electronic scales are precision instruments. Do not operate near cell phones, radios,
computers or other electronic devices that emit radio frequencies that may cause
unstable readings.

2. Unpacking and Setup
Remove the scale from the box and place it on a firm, level surface. Avoid locations with
rapid temperature changes, excessive dust, moisture, air currents, vibrations,
electromagnetic fields, heat or direct sunlight.
Adjust the leveling feet until the bubble is centered in the circle of the
level indicator (located on the front panel).
NOTE: Ensure that the scale is level each time its location is
changed.
The internal rechargeable battery should be fully charged for up to 12 hours before using
the scale for the first time.
Connect the supplied AC adapter to the power input receptacle underneath the scale.
Plug the AC adapter into a properly grounded power outlet. The battery will begin
charging.
If the scale will be stored or transported in the future, save the packaging material to
ensure the best possible protection for the scale.
