(1)仪器应保持干燥，不受腐蚀性气体的侵蚀。
 
(2)对于刚开箱或长时间未使用的仪器，好在使用前采取潮汐冲刷措施，以恢复仪器的绝缘性能。

(3)为了消除泄漏造成的误差，将仪器和拭子液容器置于清洁的塑料薄膜和其他绝缘材料中。电极的导线不应受潮。装试验溶液的容器应保持清洁，不受潮。

(4)不要将导电电极用作搅拌棒，以免损坏铂黑层。

(5)测量高电导率溶液时，由于电极电容和极化的影响，测量误差增大。为此，可将持液稀释10倍后进行测量。

(6)测量低电导率蒙皮溶液应迅速，以免空气中的二氧化碳(CO2)溶解到测试溶液中，产生碳酸盐离子(CO3)，使电导率迅速增加。另外，由于铂黑对电解层有很强的吸附作用，所以会出现不稳定的读数现象。因此，对于低电导率溶液(高纯水)，它是用明亮的电导率电极测量的。

(7)根据被测tuck的不同电导率选择导电电极。测量低电导时，用低频测量电源和铀电极;测量高电导时，用高频测量电源，铂电极镀铂黑。如果在使用中发现铂黑钳电极有故障，可将其在10%硝酸盐溶液中浸泡两分钟，然后取出再冲洗。如仍有故障，应重新镀。

(1) The instrument should be kept dry and not eroded by corrosive gases.
 
(2) For instruments that have just been unpacked or not used for a long time, it is best to take tide flushing measures before use to restore the insulation performance of the instrument.

(3) In order to eliminate the error caused by leakage, put the instrument and the swab liquid container in a clean plastic film and other insulating material 7.   The wire of the electrode should not be damp.   The container containing the test solution should be kept clean and free from moisture.

(4) Do not use the conductive electrode as a stir rod to avoid damaging the platinum black layer.

(5) When measuring high conductivity solution, the measurement error is increased due to the influence of electrode capacitance and polarization.   To this end, the holding solution can be diluted 10 times and then measured.

(6) The measurement of low conductivity skin solution should be rapid, so as not to dissolve carbon dioxide (CO2) in the air into the test solution, producing carbonate ions (CO3), so that the conductivity increases quickly.   In addition, because platinum black has a strong adsorption effect on the electrolytic layer, there is an unstable reading phenomenon.   Therefore, for a low conductivity solution (high purity water) it is measured with a bright conductivity electrode.

(7) The conductivity electrode is selected according to the different conductivity of the measured tuck.   When measuring low conductance, use low frequency to measure the power supply and uranium electrode;   When measuring high conductance, the power supply is measured with high frequency, and platinum electrodes are plated with platinum black.   If the platinum-black clamp electrode is found to be faulty in use, it can be soaked in 10% nitrate salt solution for two minutes and then removed and washed again.   If it is still faulty, it should be re-plated.
