With the digital multimeter measuring capacitance resistance

With resistance test

proves, using a digital multimeter can also look for capacitor charging process, is a reunion in the practice of the digital quantity to reflect the changes of the charging voltage. Sets the measurement speed of digital multimeter to n times per second, is in the process of observation of capacitor charging, every second can see n independent of each other and progressive increase of the readings. Based on the display characteristics of digital multimeter, can detect the stand or fall of capacitor and to estimate the size of the capacitance. Introduced below is to use digital multimeter resistance test method of capacitor documents regarding not configured capacitance meter has applicable value. This method is suitable for the measurement of 0. 1μ F ~ thousands of micro method of high-capacity capacitor. Operation method of measuring

to set the digital multimeter to the appropriate resistance, red pens and contact with black pens and distinguish between the poles of the measured capacitor Cx, will then display values from & other 000' Start adding gradually until overflow symbol display & other; 1' 。 If constantly display & other; 000' , indicate the internal short circuit capacitor; If constantly according to overflow, the capacitor electrode internally open, can also be enough when the resistance of the selected file is not appropriate. Test need to pay attention to when electrolytic capacitor, red pens and ( Positively charged) Capacitor anode, black pens and capacitor anode.

start capacitor suppliers are required in the manufacture of almost every product and start capacitor suppliers refrigerant gas is one of the most common machines.

Our mission is to operate the best specialty retail business in domestic, regardless of the product we sell. Because the product we sell is air conditioner capacitor, our aspirations must be consistent with the promise and the ideals of the volumes which line our manufacture.

Obviously, financial return is important in manufacturing refrigerant gas, but I think that's not enough. I think many customers want to support something they really believe in.
