Measuring the zener diode: we usually used regulator tube voltage value is generally greater than 1.5 V,and pointer table R x 1 k resistance is to use in the table below 1.5 V batteries,so,measured with resistance R x 1 k under voltage regulator tube like measuring diode,with full of unidirectional conductivity.But the R x 10 k file pointer motor magnet table is made of 15 v or 9 v batteries,with R x 10 k test voltage value is less than 9 v and 15 v voltage regulator tube,reverse resistance would not be up,but has a certain value,but the value is significantly higher than that of positive resistance regulator tube.So,we can preliminarily estimate the stand motor run capacitor or fall of voltage regulator tube.But,good regulator tube have a precise voltage value,amateur conditions how to assess the voltage value? Is not difficult,to find a pointer table is ok.Method is: put a watch at first R x 10 k file,the black,red pens and respectively in the cathode and anode voltage regulator tube,then simulate the electrical motor real working state of the voltage regulator tube,then take another watch on voltage profile V x 10 V or V x 50 V (according to the regulated value),will be red,black pens and respectively by receiving the watch just now black,red pens and,at this time to measure the voltage value is basically the voltage value of the voltage regulator tube.Said "basically",because the first block of the voltage regulator tube bias current relatively normal when using the electricalmotor1.blogspot.com offset current is a bit smaller,so the measured voltage value is slightly larger,but the basic.This method can only estimate voltage value is less than the pointer table high voltage battery voltage regulator tube.If the voltage value of the voltage regulator tube is too high,can only use plus method to measure the power of the (so,when we choose a pointer table,choose high voltage battery voltage is 15 v more applicable than 9 v).
