3. Remove power from the circuit.
4. Connect the test leads to the circuit.
Note:
The buzzer sounds if the measured resistance is below about
70  approximately.
Warning!
Never perform a continuity measurement on a circuit that has
power connected.
6.10. Transistor hFE
1. Turn the range switch to “hFE” position.
2. Insert test leads into “mA” and “com” jack. Please pay
attention to the polarity, as the “Com” for positive and “mA”
for negative.
3. To determine the transistor´s type, NPN or PNP, insert the
emitting, base and collector electrode into the corresponding
jacks in testing accessory.
6.11. TTL Logic Test
1. Insert red test lead into V/Ω jacks and black test lead into
COM jack
2.  shall show on LCD when the tested level > 2C;  shall
show on LCD when the tested level is 0,8 V an buzzer shall
sound as indication. There is no any indication when the
tested level ranges between 0,8 V to 2 V.
WARNING!
The tested level should be < 18 V.
