Introduction
We appreciate your using our JWP series water-proof electronic balance/counter with
single/double display and stainless steel case.
As a water-proof electronic balance which is developed by adopting the latest technology, it
features high accuracy, stable performance, accurate weighing, adequate resistance to vibration,
rapid display, firmness and durability, and convenient after-sale service. Multiple measures have
been taken to improve water-proof and moisture-proof performances of the product; in particular,
the sensor elements specially developed by our company are adopted, on which series treatments
have been done to the anti-corrosive and anti-overloading performances of the sensors. This
greatly lengthens the service life of sensors. Therefore, besides applications in general retail of
goods and quantitative packing, this product is especially suitable for applications under
conditions of high humidity, such as food and aquatic products processing. This product has been
awarded multiple national patents.
Please carefully read the Operation Instructions before using it.

4. Precautions
4.1 Common precautions
4.1.1 Please carefully read the operation instruction before using the balance so that you
may understand more about this product for your convenient use .
4.1.2 This balance is a measuring instrument subject to mandatory verification, therefore it
should be regularly sent to the authority responsible for the verification to maintain
its accuracy.
4.1.3 Overload is strictly forbidden. Never throw a heavy substance at the balance or
impact it heavily. Any part of the balance damaged due to the above maloperations
is out of our warranty.
4.1.4 Never let the balance contact chemicals such as solvents to avoid corrosion.
4.1.5 Keep the balance clean, and no foreign matter is allowed to exist around the balance
pan, otherwise, the accuracy of balance may be affected.

4.1.6 Users must not open the lead seal on the bottom of balance. Should any trouble occur,
please contact dealers or manufacturer of the balance.
4.2 Precautions for application of the hermetic lead acid batteries
4.2.1 The batteries in this balance are maintenance-free hermetic lead acid batteries, which
features low self-discharge rate and long service life. Its operation temperature is
-10℃~+40℃, and its discharging and charging cycle is about 300 times at a
temperature of about 20℃.
4.2.2 Make sure that the connection with the negative electrode and the positive electrode
is correct while replacing the batteries, otherwise, the batteries will be damaged and
a fire may be caused. The correct connection is as follows: the red line is to be
connected with the plug with red mark, and the black line is to be connected with
the plug with black mark.
4.2.3 The batteries should be recharged in a timely manner when its power is run out (the
indication of low power appears on the screen). In case a balance will be left idle
for a long time, its batteries should be fully charged before its storage, and should
be charged at least once every three months.
4.2.4 The capacity of batteries will decrease gradually along with the increase of
charging/discharging times, that is, the operation time of recharged batteries will
become shorter and shorter, which reflects the characteristics of the rechargeable
batteries. The original batteries should be replaced with new ones if the former
needs charging soon after the previous charging,
4.2.5 Considering that the lead acid batteries are consumable, and its service life depends
on users’ application methods, therefore, the warranty period for batteries is only
one month.
