mga master ask ako saan makabli ng ac volt meter 30 volts mpara sa zener diode tester ko,ang zener diode tester kce has the capablity to mesure volt of zener diode from 2.5 to 24 volts,and also has the capblity to test components part,that our analog tester connot,zener diode tester can test in under load reading.can test diode,regulator,battery,led,etc,,tnx

maganda po yang tester nyo ah.. ano yung Brand nya baka pwede malaman..

Ilan ang Voltages supply ng Tester nyo po? kasi kung kaya ma itest ang rating ng isang Zener up to 24V ano po yan malalaman ang mismong rating ng isang diode kahit burado ang body marking.

ako pag nagtest ako ng zener sinu suplayan ko ramp-up tapos monitor ko kung saan sya mag hold ng voltages yun ang rating nya.

ano sa tingin nyo mga MASTER........................

sa aking naman xformer lang na 2 x 22 = 44v x1.4 (50v) zener diode kayang basahin.

A better approach if you want - is to use a constant current source capable of supplying 5mA and a compliance voltage of 40+ volts. Checking a zener diode is just a matter of connecting it to the current source and measuring its zener voltage. This approach eliminates the need to ramp up the voltage. It is also offers automatical protection against shorted zener diodes or connecting the zener diode in forward direction.
