Thank for your purchasing of our Weighing Scale. To
guide you to use our product correctly, please read
this User Manual carefully to extend the life of
machine and to avoid error.
Instructions for Use
1. Please keep scale in a cool and dry place. Do not store under high temperatures.
2. Please keep the scale clean and free from insect infestation.
3. Avoid impacting with other items or overloaded with excessively heavy weights.
(The load must not exceed the maximum capacity of the scale).
4. If the scale is not going to be used for some time, please clean it and store it in a plastic
bag in dry condition. A desiccant sachet may be included to prevent moisture from
building up.
5. Any suggestion is warmly welcome.
Preparing to Use the Scale
1. Locate the scale on a firm level surface free from vibrations for accurate weight readings.
Adjust the four leveling feet to centre the leveling bubble on the scale.
2. Avoid hot sunshine directly on the scale or near the exhaust port of ventilating system.
3. Please use a separate power source plug, to avoid the disturbance of other electric
appliance.
4. There should be no weight on the scale when power is turned on.
5. Commodity should be placed at the centre of platter when being weighed, and its size
should not exceed the dimension of the platter.
6. We suggest to warm the scale for 15 ~ 20 minutes before using.。

7. Please note that when
needs to be recharged. The indicator could only operate for another 6~8 hours. Then
“ . . ” shown on the display and the indicator must be fully charged before operating
again.
8. Introduction of Storage Battery

ZSME3000000314
Due to the storage battery adopt the advanced free-maintaining technique, customers need
not to replenish electrolyte.
The scale should be recharged every 3 months to prevent failure of the internal
rechargeable battery.
1. The battery should be charged for 8~10 hours.
2. The temperature of battery should below 45℃.
Maintaining
1. Please do not discharge with over-current when using the battery. Please charge the
battery after discharging current.
2. Please take down the battery when the scale is not used for a long time or break the
connection of cathode.
3. Do not short the battery terminals to check whether there is current. Please check
whether the connection point is firm to guarantee good connection.
4. The battery should be replaced by specialized person. No reverse-battery or the
product will be damaged.
a) Anode of battery should be connected with Anode of product battery(usually red
cable)
b) Cathode of battery should be connected with Cathode of product battery (usually
brown cable or black cable)
c) See the picture following
Brown cable(or black cable)
connected with Anode of
battery
Red cable connected with
Cathode of battery
Safety warnings
1. The electrolyte of battery is caustic which causes metal, cotton, etc to corrode.
2. The hydrogen will be resolved when using or charging the battery and it will cause
explosion when approaches fire.
No burning

n Place the container onto the scale, until the weight value is stable, press
zero return and the NET indication is shown on the display.
o Place the object into the container and the display shows the net weight value of the
object.
p Remove both object and container, and negative value of the container will show on the
display. Press
again to clear “tare value”. The scale returns to zero and NET
indication goes off.
Tare can be continuously done until tare value=maximum capacity
Continuous Tare ⇒ Press
key for continuous weight increase/decrease on platter.
If there is Tare, the pre-tare cannot be done. If there is pre-tare first, and the tare weight
Is more than pre-tare weight, Tare can be done.
No Tare can be done under gross weight display mode.
Pre-Tare Function
When there is nothing on the platter, press
key and use keypad to input pre-tare weight.
When the cursor flashes on the last digit of display, press
key again to complete.

transmits the format of simple mode or complete mode.
This key is the combination key. while total counts is shown and weight returns to net zero,
press
key to clear data and RS-232 transmits the MC printing format.
If there is new weight added on platter, a new data will be added to accumulation data. If
this weight is not taken off, nothing can be added to accumulation data. Display will
show the total counts for one second, then show net weight for one second, then the
display returns to the current weight.
Clear Accumulation data: Press
key and the total counts shows on the display. Press
key again to clear accumulation data.
Weight must return to net zero if to perform clear function
