Diode Measurement; Transistor Hfe Measurement; Audible Continuity Test - Mercury MTB01 User Manual

3. If the resistance being measured is connected to a
circuit, turn off power and discharge all capacitors
before measurement.
4. Connect test leads to circuit being measured.
5. Read resistance value on Digital Display.

DIODE MEASUREMENT

1. Red lead to "VΩmA", Black lead to "COM".
2. Set RANGE switch to "
3. Connect the red test lead to the anode of the diode to
be measured and black test lead to cathode.
4. The forward voltage drop in mV will be displayed. If
the diode is reversed, figure "1" will be shown.

TRANSISTOR hFE MEASUREMENT

1. Set RANGE switch to the hFE position.
2. Determine whether the transistor is PNP of NPN type
and locate the Emitter, Base and Collector leads.
Insert the leads into the proper holes of the hFE
Socket.
3. The meter will display the approximate hFE value at
the condition of base current 10μA and V

AUDIBLE CONTINUITY TEST

1. Red lead to "VΩmA", Black lead to "COM".
2. RANGE switch to " " position.
3. Connect test leads to two points of circuit to be tested.
If the resistance is lower then 30Ω±20Ω, the buzzer
will sound.
