* Overload

When an applied load exceeds the capacity. “EEEE” will appear on the display. Remove the excessive load immediately!

!Remember: You can permanently damage the scale by overloading it!

* Negative Value

Any tarred value or a value left in memory will be displayed as a negative number once all weight is removed from the unit. Press tare to re-Zero the unit.

* Auto off

An auto shut off feature is provided to conserve battery power. The unit will automatically turn off after approximately 3 minutes of inactivity.

* UNIT (the left key)

KEY PAD FUNCTIONS

Unit (mode) selection: Press and hold the left key to change weight unit You can select g (grams), oz (ounces), dwt

(pennyweight) or ct (carats).

* ON/OFF

Press this key to turn unit on. Once the unit is on, press and hold the same key for 5 seconds to turn the scale off

* Tray Operation:

The spinning locking mechanism of the Mini is designed to protect the scale from accidental overload when it is closed.

Simply spin the cover counter clockwise so that the LCD and buttons will be hidden from view. The scale is now ready for storage

To operate the sale simply spin the cover clockwise until it is fully open (you’ll feel it lock into place). Now the scale is ready for use.

NOTE: Always close the cover when storing the scale. Please be sure the cover is fully open before operation.

* ZERO (TARE)

After the scale is ON, you can press to reset the scale to zero. This can be used for eliminating from a sample (or a

Tray/Container) the weight value of a container weight is permanently removed for the remainder of the procedure. Just turn the scale ON, place the tray or container on weighing platform, and press the key. The scale will show 0.0 (or 0.00) on the display and you can add items to the container/tray.

NOTE: When all weight are removed from the weighing tray, the tared value of a container will be displayed as a negative number.

Cycle the power on the scale to reset the scale to zero.

** These electronic scale are precision instruments. Avoid disturbing environmental conditions such as currents, vibrations, strong electrical and magnetic fields as well as a rapid change of the ambient temperature.

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 LLLL or EEEE, 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 #1 above) Thus, if new batteries do not fix this error the scale will have to be sent to us for replacement under our 5 year 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 JS is designed to be extremely durable, It ’ 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’s sensors are damaged.
