Testing Diodes - DATATEC EDU34450A Guia Del Usuario

– Input Protection: 1000 V (HI terminal)

Testing Diodes

1. Press [Shift] > [Cont] |
2. Connect the terminals as shown below (either to test the reverse bias diode position or the forward bias diode pos-
ition).
3. Read the display.
– For the reverse bias diode position: OPEN is observed if the diode is good.
– For the forward bias diode position: A value ranging from 0.3 to 0.8 V is observed if the diode is good (for most sil-
icon diodes).
– If OPEN is observed on both directions, the diode is bad.
– If a 0 V to 0.4 V drop is observed on both directions, the diode is shorted.
