Introduction
Thank you for purchasing the American Weigh PS-25 digital
postal scale. Please read all operating instructions carefully before
use. Scales are precision measuring devices and should always be
handled with proper care. To ensure years of reliable service, keep
these simple tips in mind:
• Do not exceed the scale’s 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, calibration and adjustment may be necessary.
• Allow your scale to warm up for 30-60 seconds before
performing calibration and adjustment(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 your scale in close proximity to strong radio wave
emitting devices such as computers, cash registers, and
cordless phones.
• Alwaysweighonaatandlevelsurface,freefromvibrations
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.
• Checkthebatteriesrstifyouarehavinganytroublewithyour
scale. This simple step can remedy most scale issues.
• Do not disassemble your scale. This product contains no user
serviceable parts.

lb:oz (pound:ounce)
VII. Using the Tare Feature
You can use this scale’s tare feature to subtract the weight of an
empty container or vessel for net weight determination. NOTE: The
weight of the container will subtract from the available capacity.
1.Place the empty container or vessel on the weighing platform.
2.Press the TARE key once. The display will then reset to zero.
If the container is removed, it’s weight will be displayed as a
negative number.
3.Youmaynowllthecontainerwiththequantitytobeweighed.
The display will show the net weight of the contents.
4.To return to normal weight display (gross weight), remove any
items from the weighing platform and press the TARE key
again to re-zero the scale.
VIII.Calibration (Advanced Users Only)
Calibration and adjustment are performed at the factory. Only
trained technicians should perform calibration and adjustment
if the scale is not weighing properly. Do not proceed with
calibration without the proper 10kg weight with class M2
or better or you could cause your scale to be inaccurate.
Calibration is not covered under warranty.
1.Place the required calibration weight on the scale and note the
displayed value.
2.If the displayed value is not within acceptable tolerance (see
chart below), adjustment is required.
