7. If the junction is measured in a circuit and a low reading is obtained with both
lead connections, the junction may be shunted by a resistance of less than
1kW . In this case the diode must be disconnected from the circuit for
accurate testing.
Capacitance Measurements
1. Set the Function/Range switch to the desired "
Blue toggle button to select Cx.
2. Never apply an external voltage to the Cx sockets. Damage to the meter
may result.
3. Insert the capacitor leads directly into the Cx 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.
Frequency Measurements
1. Set the Function/Range switch to the Hz position.
2. Connect the red test lead to the "VW " jack and the black test lead to the
"COM" jack.
3. Connect the test leads to the point of measurement and read the frequency
from the display.
