Continuity Measurements
1. Set the Function switch to "
" position.
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. To toggle between the continity/diode modes, press Range Switch.
4. Connect the test leads to the two points at which continuity is to be tested.
The buzzer will sound if the resistance is less than approximately 20
W
±5
W
.
Capacitance Measurements
1. Set the Function/Range switch to the desired capacitance range.
2. Never apply an external voltage to the
sockets. Damage to the meter
may result.
3. Insert the capacitor leads directly into the
socket.
4. Read the capacitance directly from the display.
Transistor Gain Measurements
1. Set the Function/Range switch to the desired hFE range (PNP or NPN type
transistor).
2. Never apply an external voltage to the hFE sockets. Damage to the meter
may result.
3. Plug the transistor directly into the hFE socket. The sockets are labeled E,
B and C for emitter, base, and collector.
4. Read the transistor hFE (dc gain) directly from the display.
