FEATURES____________________________________________
* Power Up Segment Test: When first turning the unit on, all segments of the display will appear as shown below. 
This display will remain for approximately 3 seconds and then reset to zero. The display may also change 
brightness during this time and show a blank screen for a moment before 0.0 appears
=8.8.8.8.8 >

Stable Reading Indication: This is a very precise scale - the display may seem to wander or jump when weighing. 
This is due to air currents or vibrations. Stable weighing is achieved when the display remains fixed for 3 seconds.

* Overload: When an applied load exceeds the capacity. “HHHH” will appear on the display. Remove excessive 
load immediately. The unit may return to normal operation. !Remember: You can permanently damage the scale 
and void your warranty by overloading it!

* Negative Value: Any tared value will be displayed as a negative number once all weight is removed, press TARE 
or cycle the power to re-zero the scale.

* Auto off: An auto shut off feature is provided to conserve battery power. The unit will automatically turn off after 
approximately 2 minutes of inactivity.

*Stable Indicator: There is a “o” stable indicator that appears on the left side of the LCD whenever the scale is 
stable and at Zero

* Special Tray/Cover
The protective cover of the MX is designed to also be used as a platform expansion tray. Simply remove the cover, 
turn it upside-down, and place it on the scale

ʼ

s weighing platform. Now turn the scale ON and the scale will 

automatically TARE (zero) itself with the tray on the scale.(if this does not work properly, you can turn the scale ON, 
then place the upside down cover on the tray and press the TARE key) This is perfect for weighing loose objects, 
gunpowder, gems, Chinese herbs and more.
Please keep the protective cover installed when the scale is not in use (it will help protect the scale from possible 
damage)

MX TROUBLESHOOTING & OPERATION NOTES:
1) If the Display ever becomes locked showing "Out2", please recalibrate the scale as outlined in the manual
2) If the Display ever becomes locked on LLLLL, or EEEEE, this indicates that the scale was shocked, dropped or 
otherwise damaged and the delicate weighing sensors have been damaged. You can try recalibrating the scale (If 
the sensor has not been hurt too badly it will work again after recalibration). Otherwise you will have to follow the 
warranty instructions that came with your scale.
3) If the display becomes locked on 8888, this often indicates low batteries. However sometimes it also may 
indicate a serious zero mark error. This means when you turn the scale on, it can't determine what zero is (a slight 
zero mark error will cause situation #2 above) Thus, if new batteries do not fix this error the scale will have to be 
sent to us for replacement under our warranty program.

4) If the display shows UNST, this means the scale is not stable. Please try operating the scale on a more stable 
surface and be sure nothing is on the tray or stuck under the tray when you turn it on. If this situation persists, it 
may be an indication of fatal load cell damage. Try calibrating the scale - if this does not work please follow the 
warranty instructions.
Although the MX is designed to be extremely durable, It

ʼ

s important that you never overload or drop/shock the 

scale. Scales are delicate instruments and unlike Cellular phones, scales have delicate sensors that determine how 
much an item weighs. If you drop or shock your scale, these sensors "feel" the shock and are sometimes 
destroyed. This happens with all digital scales. We design our scales to be as resistant to shock or drops as 
possible, however there is no way for us to protect 100% against load cell or sensor damage. A well-treated scale 
will provide years of reliable and accurate weighing. However an abused scale will only work until it

ʼ

s sensors are 

damaged.
