It required an ohmmeter multitester or an analog / digital. Multitester or Avometer Analog has facilities measuring barrier (ohmmeter) where the type normally used ohmmeter ohmmeter-series, which is the construction of the polarity of the batteries installed in the meter opposite in polarity to the measuring terminal. Or in other words, the positive terminal meter is having a negative polarity battery, reverse the negative terminal of battery meter has a positive polarity.
Thus in order to test a diode by using Avometer principle is as follows:
- Your position Avometer ohm position with sub-scale
- Decide in advance the electrode anode and cathode of the diode
- Connect the terminal + (positive) meter with the anode of the diode to be tested while the terminal - (negative) meter with the cathode of the diode. (This relationship is the reverse)
- In this position, if the diode is good, then the meter needle will not move. However, if the needle moves in this position, it can be said short-circuit diode (defective).
- Repeat step 2 above with the opposite polarity, which is connected with the negative meter Anode and Cathode with positive meters. (This relationship is forward).
- In this position, if the diode is good, then the meter needle will move. But if in this position the needle meter does not move, it can be said diode broke (broken).
itulah pembahasan singkat cara menguji dioda dengan ohm meter. semoga dapat bermanfaat. maaf bila banyak kesalahan, karena ini dari google translate
