1. Electronic scale when the need to recharge, pay attention to the external adaptation (step-down power) rated output voltage whether, with the "table" matching scale ￠6 the polarity of the plug is correct (voltage can be 10% of the positive and negative difference) also note at the beginning of the adapter is highly rated voltage 110 v and 110 v, don't make a mistake. (9 v of no-load voltage should be more than 12 v, pay attention to the rated power of the transformer is greater than 15 w, the quality of silicon steel sheet is better. Otherwise, will cause no into current.

2. Weighing display instrument tip need to recharge when charging, don't waste the increase of the number of charging (because the best lead-acid storage battery charge and discharge can be at most 350 times, the average product is 300 times or so, otherwise it will reduce the service life of the battery, to bring economic loss to the customer. A case/scales are configured 6 V / 4 a battery, adequate electricity, LED display can be used 80 hours, 120 hours may be used in LCD display, so we can calculate the normal service life of the battery is 24000 ~ 36000 hours. Such as: some unit using weight scales to work 12 hours a day, adequate electricity can be used after 6 days, don't make a battery voltage below 5.5 V, and will charge the battery into the current, not cause battery scrap. Electronic long-term need not when, in charge should be once every two months, in order to avoid the battery discharge)

3. The charging circuit are all intelligent instruments company, through the color change of the charge indicator, reflect the working state of the battery is charging, basically as "must charge (dark red) - orange - yellow to yellowish green, green (complete charging process) usually charging time is 12 ~ 15 hours.

4. To work in damp, dust, large temperature difference of the environment, should be promptly eliminate interference suspicious and do the corresponding row of tide, cooling, dust and other maintenance work. Especially moisture balance, to regularly check to balance body sealing parts, such as: waterproof skin is broken, the base is damaged, screw fastening, charging plug is broken, battery compartments within the moistureproof agent originally (white) is to green should check the sealing performance of the battery cover. The above part are different Often deal with sealing parts, replacement parts, replacement of seals. (e.g., found that when there is no elastic sealing strip, it must be replaced, pressing sealing strip, interface to align, crowded, no discount phenomenon) fastening screws to tighten when used according to the order of the diagonal. (the strength should be appropriate, cannot use ?

5. Check regularly check of sensor, it will be affected with damp be affected with damp, oxidation, moving parts around to see if there is foreign body, found that abnormal should be clear in time when maintenance. Simple moistureproof balance anticorrosion measures in protective layer of elastic beam sensor (coated white silica gel) and then apply a layer of butter, so that we can have the effect of moisture. Note: butter don't apply to load sensitive parts of the elastic beam.

6. In electronic circuit boards, should be kept clean, no dust all sorts of sundry, if there is a phenomenon of be affected with damp be affected with damp, after drying, coating a layer of insulating varnish, to facilitate the protection of circuit board, improve the moisture-proof insulation performance of the circuit, the connectors should contact is good, the wire does not have poor contact or leakage phenomenon. Replacement of circuit components, must be replaced for professional maintenance, users do not touch.

7. Electronic scale (instrument) shell basically is to use plastic products, so should be paid attention to in daily use away from the corrosive solvent and gas, it can prolong the service life. Should avoid strong impact, extrusion, etc. Always keep clean, found the problem urgent to solve.

8. The electronic weighing apparatus should be as far as possible avoid long-term work in high temperature or very low places, such as must work in dirty environment, should rest for a period of time (30 minutes) before using, this is determined by the sensor and the temperature characteristic of electronic components, they should have a temperature adaptation to the normal work, otherwise there will be weighing no phenomenon
