Function Description
Diode test Indicates the direct voltage drop in the diode
Transistor test Range: 0 - 1000; Test current Ibase = 10 μA; Test voltage Vce = 2,8 V
Circuit continuity test
(buzzer)
If the resistance of the tested circuit is less than 30 ± 20 Ohm, the
buzzer sounds. Overload protection: 15 s, 220 V DC/AC (RMS)
