mini PRO User’s Manual
Thank you for purchasing the mini PRO Portable Precision Balance.
With normal care and proper treatment, it will provide you with years of
reliable service. Please read all operating instructions carefully before
using the scale.
•Avoid any exposure to extreme heat or cold. Your scale will work
better when operating in normal room temperature. Always allow the
scale to acclimate to normal room temperature for at least an hour
before use.
•Give the scale sufcient warm up time before use. Usually 30 to 60
seconds to give the internal components time to stablize.
•Keep your scale in a clean environment. Dust, dirt, moisture, vibra-
tion, air currents, or a close proximity to other electronic equipment can
cause an adverse effect on the reliability and accuracy of your scale.
• Handle with care. Gently apply all items to be weighed onto the
weighing surface. Although this scale is designed to be quite durable,
avoid rough treatment as this may permanently damage the internal
sensor.
• Do not shake, drop, or otherwise shock the scale. This is a precision
instrument and must be handled with extreme care.
• Only operate the scale on a stable, vibration free surface.
• Always store in a dry place to avoid moisture accumulation on
internal components.

II. Operation
This scale operates using either 4 AAA batteries or an included
AC Adapter. Insure the scale is plugged into a wall outlet, or
has battery power before use. To operate, set the balance
on a at / stable surface away from interference from wind,
vibration, and radio waves. If needed, you may adjust the
scales feet to insure that the scale is level. Press the “On/Off”
key to begin weighing. Once the scale reads “0.000”, you may
place the item to be weighed onto the center of the platform.

III. Weighing Units
This scale can weigh in either grams, ounces, troy ounces,
pennyweights, grains, or carats. To change the active weighing
unit, press the “Units” key. The scale also remembers the last
unit used. Therefore, the next time the scale is turned on, it will
revert to the previously used weighing unit. You may change
weighing units in the middle of weighing as well.
IV. Tare Feature
Tare allows you to subtract the weight of a container (ie. the
included weighing tray) in order to obtain the weight of objects
in the container (net weight). To use the scales “Tare” button,
turn the scale on in normal weighing mode and wait for the
screen to show “0.000”. Place the container you wish to use
on the scale then press the “Tare” button. The weight of the
container is now subtracted and the scale should read 0.000
again. If you now remove the container, a negative value will
be shown. If you wish to clear the negative value, press “Tare”
again.
V. Backlight
This scale has a backlight with adjustable settings. To change
the backlight’s parameters, press the “Fn” key two times. The
scale will display F1, meaning the backlight will come on when
weight is on the scale. To cycle through the different modes,
press the “Unit” key. Press the “Tare” key to conrm your
selection.
F1: Backlight will come on when weight is on the scale.
F2: Backlight is always on.
F3: Backlight is always off.
VI. Auto-Off Feature
This scale has an Auto-Off feature that can help extend battery
life by turning the scale off when not in use for a set amount
of time (1-9 minutes). To change the Auto-Off timer, press the
“Menu” button three times. The scale will show the current
Auto-Off setting (OFF, 60, 120, 180, 240, 300, 360, 420, 480,
or 540)
Press the “Unit” button to cycle through until you nd the
desired timer duration (in seconds). Press “Tare” to conrm
your selection.
VII. Calibration
This scale is calibrated at the factory, but frequent use or
slight shock can sometimes affect the calibration. In such
cases you may need to recalibrate the scale. Typically, the
Standard Calibration method is sufcient for the average
user to recalibrate their scale. Advanced calibration is already
performed at the factory and should not be attempted unless
you have two calibration weights. Before starting calibration,
insure that the area you are working on is free of any drafts,
vibrations, and you are using a at level surface
• Standard Calibration (Span):
**MiniPRO-50 calibrates with a 20g or 50g weight.
**MiniPRO-100 calibrates with a 50g or 100g weight.
Press the “Menu” button one time, “SCALE” will be displayed
on the LCD; Press the “Tare” button to continue. The scale will
display the required calibration weight. You can press “Unit”
to change between the two available calibration weights (see
above). Press “Tare” to conrm. The value on the display will
ash. Place your calibration weight onto the weighing platform.
• Advanced Calibration (Linear):
You will need two weights to perform Advanced Calibration:
**MiniPRO-50 takes a 20g and a 50g weight.
**MiniPRO-100 takes a 50g and a 100g weight.
Press the “Menu” button one time, “SCALE” will be displayed
on the LCD; Press the “Units” button once to change to “LINE”
mode, then press “Tare” to conrm. The scale will display
the rst required weight. Press “Tare” again to conrm. The
value will ash on the display. Place the rst required weight
onto the weighing platform. In a few seconds, the display will
show the second required calibration weight. Add the second
weight to the platform. After a few more seconds, the weight
will be accepted and the scale will return to normal weighing.
Calibration is complete!
