Precautions Before Using The Scale
The scale should always be used in an
environment that is free from excessive air
currents, corrosives, vibration, and temperature
or humidity extremes. These factors will affect
accuracy and performance. Please check
www.myweigh.com for the latest version of this
manual, in case of possible revisions.
Scale Operation Notes
·Do not Overload ( exceed the capacity ) of the
scale including the weight of any trays or bowls
combined with objects you may be weighing.
Overload or Dropping/shocking the scale will
damage the sensor and void your warranty.
·Allow sufficient warm up time. Turn the scale
ON and wait several seconds to give the internal
components a chance to stabilize before weighing.
·The cleaner the environment the better. Dust,
dirt, moisture, vibration, air currents and
proximity to other electronic equipment can all
1

cause an adverse effect on the reliability and
accuracy of your scale.
·Handle with care; Gently apply all items to be
weighed onto the tray. Although this scale is
designed to be quite durable, avoid rough
treatment as this may permanently damage the
internal sensor and void your warranty.
·Avoid lengthy exposure to extreme heat or
cold, your scale works best when operated and
stored at normal room temperature.
·Place the item to be weighed on the platform,
after the stable weight is displayed remove the
item immediately. This will prolong the longevity
and accuracy of this weighing instrument.
Turn on The Scale
Press ON/OFF to turn on the scale. The scale
will go through a quick warm up procedure and
self test, then it will be ready for use.
Display Window
:Current reading is stable.
:Scale is in ZERO mode.
2

: Scale is in TARE mode.
or “Lo” : Battery is at low voltage.
“OVER LOAD” : The weight is above the capacity.
KEY PAD FUNCTIONS
MODE
Press and release the key once to change the
weight unit.
ON/OFF : Power Switch
Press this key to turn the scale on. Once it is on,
press and hold the same key to turn the scale off.
TARE : Zero or tare
Press TARE to reset the scale to zero, When the
weight on the tray is below 5% of the
maximum capacity of the scale, pressing this key
will reset the scale to zero mode. This key is also
used as a TARE function when the weight on the
tray is above 5%. The tare indicator will
appear and the display will show 0.0 (0.00)
Battery Operation:
1) Two CR2032 Lithium Cell battery (3V*2) are
3

required. Before replacing batteries, always
remember to install the Scale’s cover & be
careful NOT to push on the weighing platform
(this can cause a fatal overload even if the
power is off).
2) To install batteries:
a)Release the battery cover by sliding
out-wards.
b)Place batteries into the battery compartment
aligned correctly.
c)Replace battery cover.
3) The scale is now ready for battery operation.
(Advanced users only) CALIBRATION
IMPORTANT: This scale was professionally
factory calibrated before shipment. It usually
does NOT need to be recalibrated before use.
However advanced users may wish to calibrate
the scale periodically to maintain perfect
accuracy. Incorrect calibration can occur if you
do not follow the steps exactly. You will need an
accurate calibration weight to calibrate this scale
(MXT-100 uses a 100g weight, MXT-500 uses
4

a 300g weight). In emergency situations you can
use coins or known-weight items as a temporary
calibration weight (ie 20 US Nickels= 100g).
1) Place the scale on a FLAT, very stable surface
and turn the scale on.
2) Press and hold MODE for 3 seconds until the
display shows “CAL” and then the required
calibration weight will be displayed (ie 100.00).
3) Place the required calibration weight on the
tray, wait 3 seconds, then press ON/OFF .
Calibration is complete.
NOTE: If after calibration your scale does not
read accurately, this indicates calibration error &
the calibration process should be repeated more
slowly.
Please calibrate on a very stable flat surface!
INACCURACY/ERROR
The primary reasons for inaccuracy or
malfunction are low batteries, incorrect
calibration, overload or operating on an unstable
surface. Please keep this in mind and maintain
5
and operate your scale properly. The scale is a

precise instrument and must be handled with the
utmost care and caution.
FEATURE
 Power Up Segment Test
When the scale is first powered on, all
segments of the display and indicators will
appear “-18888”.
 Overload
When an applied load exceeds the maximum
capacity of the scale. The display will show
“ O-Ld ”, & “ OVER LOAD ”, Remove the
excessive load immediately!
Remember: You can permanently damage the
scale by overloading it!
 Negative Value
Any tared value or a value left in memory will
be displayed as a negative number once all
weight is removed from the tray. Press TARE to
re-Zero the unit.
NOTE ：All items should be placed on the
center of the weighing tray.

TROUBLESHOOTING & OPERATION
NOTES:
1) If the Display shows “OVEr”, this indicates that
the scale was shocked, dropped or otherwise
damaged and the delicate weighing sensors may
have been damaged. You can try recalibrating
the scale. If that does not work then please follow
the warranty instructions that came with your
scale.
2) If the display is faint or the scale won’t power
on, this often indicates low batteries. Thus, if new
batteries do not fix this error the scale will have to
be sent to us for replacement under our warranty
program.
