PRECAUTIONS
1. Avoid exposingthe scale to high temperatures anddamp conditions.
2. Keep the scale clean and avoid insects from enteringthe scale.
3. Avoid heavyobjects impactingwith the scale.
4. The load placed on the weigh pan must not exceedthe maximum weighingcapacityof the scale.
5. If the scale is not to be used for an extended periodof time it is recommended that the scale is
cleaned and stored in a plastic bagin dryconditions. A desiccant maybe included.
6. Remove the plastic drip cover from the scale for best weighingaccuracy.
7. We welcome anycomments or suggestions that you mayhave about this product. Please contact
your dealer.
PREPARINGTOUSE THE SCALE Ⅱ
1. Locate the scale on a firm level surface free fromvibrations for accurate weight readings.
2. Adjust the four feet underneath the scale to ensure the bubble level”is in the centre position.
3. Do not place the scale where the temperature changes dramaticallyor in a location where draft can
affect the weighing. Example: Do not expose the scale directlyto sunlight or air-conditioningunits.
4. If possible connect the scale to an electric socket separate from other appliances to avoid
interference.
5. Do not leave anythingonthe scale when it is not in use or when switchingit on.
6. Please locate thegoods in the centre of the weighpan. It will ensure best accuracyof the weight.
7. It is recommended that the scale is warmed up for15-20 minutes before use.
8. Recharge the internal battery, as appropriate, when low batterysymbol is displayed. .
9. The overall dimensions of the goods beingweighed should not exceed the dimension of the weigh
pan.

ErrorMessages:
⇒The EEPROM memoryis not workingcorrectly.
⇒Zero is higher than the zero range when switchingthe scale on.
⇒Zero is lower than the zero range when switchingthe scale on.
⇒A/D value is unstable.
⇒A/D value is lower than -31250.
⇒A/D IC malfunction (cannot read A/D value). The load cell maynot be connected to the
scale correctly.
⇒A/D value is higher than +31250.
⇒The weight of the object is over the maximum capacity+ 9 divisions.
⇒After calibration the displayed resolution is greater than the internal resolution.
⇒The gravityvalue isoutside the range 9.772 ~ 9.829.
⇒Error setting.
⇒The weight value is higher than the zero range, when re-zeroingthe scale.

Ⅴ KEYBOARD FUNCTION
1. : OFF key.The keyused to switch the scale off.
2. : On /Zero Key. Toswitch on the scale or to re-zero the displayif thereadingis not zero and
there is no load on the weigh pan. (Zero range:±2% of scale capacity)
3. :TARE key. Press the keyto deduct the weight of a container.
vThe tare key works whenthe weight value shown on the displayis negative or over the full scale
capacity.
4. : Units key.Pressthe keyto select the desired weight units or countunits (pcs).
