路盛蓄电池在使用中教你如何维护与保养 检测  调试

1.为了延长电池的使用寿命，其充电时间不可超过必要的充电期（锂电池一般不超过12小时）
2.只用购机时厂家原配的充电器
3.电池的触点不与金属或带油污配件接触，注意防潮
4.电池切勿浸在水中或者扔在火中
5.电池切勿放在低温如冰箱里、高温如炉子旁
6.如需更换电池，请只用手机生产厂家认可的电池类型
7.对于有记忆效应的电池，每次应把电量使用完毕，再充电，否则电池会出现记忆效应，大大减少电池的寿命。
8.电池的使用寿命是按充放电周期来计算的。因此，充足电用完后再充，能最大限度的延长电池的寿命。

1) Maintenance of pH test pen and matters needing attention

This test pen has been calibrated and can be used directly when it leaves the factory. The following conditions need to be re-calibrated:

It has been used (or placed) for a long time after calibration.

Electrodes are used very frequently.

The requirement of measurement accuracy is relatively high.

When correcting, do not reuse the correcting buffer.

When the pen has white crystals, this is a normal phenomenon. Don't be nervous, soak in clear water for a period of time.

Drop a few drops of preservation solution or correction buffer in the pen case. Do not use distilled water or pure water to immerse or preserve the test pen.

There may be small bubbles in the sensitive bulb of the pen glass electrode, which will affect the normal measurement of the electrode. When using, the electrode should be shaken to make the bubbles run out of the sensitive bulb.

Glass electrodes are easy to break and should be carefully used.

Batteries should be replaced if the display value is ambiguous or not or much higher or lower than the real PH value of the solution.

2) Method of battery replacement

The black board with switch on the pen is gently pulled out. Do not pull off the wire. Four 1.5V batteries can be seen and replaced.

Pay attention to battery polarity and choose the same type of battery.

When the electrode is inserted into the liquid to be measured or the buffer to be corrected, it shall not exceed the maximum height indicated on the test pen.

If the electrode is placed for a long time and the sensitive bulb is exposed to the air, the response is slow and the display value is unstable due to the drying of the electrode. At this time, the electrode should be immersed in distilled water to activate for several hours.

To improve the performance, the electrodes of the PH meter are inserted into distilled water at least once a week for several minutes each time.

Protein precipitates (such as milk cheese, etc.) are immersed in pepsin and hydrochloric acid solution for elimination. The solution is prepared before use, and after use, the electrodes are immersed in the solution for several hours, then rinsed with clean water, and then immersed in distilled water for several hours.

Oil film also affects the measurement of sensitive bulbs. Li removes the film, rinses the sensitive bulbs with 75% alcohol solution, dries them with filter paper, rinses them with water, and then immerses them in distilled water for several hours.

3) pH calibration

The test pen electrode was immersed in a mixed phosphate standard buffer with a PH value of 6.86 (at 25 C) and shaken slightly.

Adjust the calibration potentiometer with a small screwdriver until the display value is consistent with the PH value of the standard buffer solution at ambient temperature.

The electrode was inserted into the standard buffer solution of potassium hydrogen phosphate phthalate (PH4.01) or borax (PH9.18).

The display value should be within the allowable error range when compared with the PH value of buffer solution.

4) Procedures and methods of operation

Remove the protective sheath;

First, the electrodes of the PH meter are cleaned with distilled water, and the water attached to the electrodes is absorbed by filter paper.

Switch on the switch located on the battery bin.

The electrodes of the PH meter are inserted into the tested liquid until the immersion of the liquid is slightly below the "immersion line". If the conditions permit, the solution can be immersed slightly above the "immersion line".

Gently stir the solution until the value is stable, then read the display value.

After using, clean the electrodes, turn off the switch and put on the protective cover.
