4.3. AC VOLTAGE MEASUREMENTS
1. Connect the red test lead to the "VŸP$ MDFN DQG WKH EODFN OHDG WR WKH &20 MDFN
2. Place the RANGE switch in the appropriate VAC position. Set the switch to the highest
range and work your way down if the voltage range is unknown beforehand.
3. Connect the test leads to the device or circuit to be measured.
4. Activate the device or circuit to be measured. The voltage value will appear on the
display.
4.4. DC CURRENT MEASUREMENTS
1. Connect the red test lead to the "VŸP$ MDFN DQG WKH EODFN OHDG WR WKH &20 MDFN
(Connect the red test lead to the "10A"-jack for measurements between 200mA and
10A).
2. Place the RANGE switch in the appropriate ADC position. Set the switch to the highest
range and work your way down if the voltage range is unknown beforehand.
3. Open the circuit to be measured and connect the test leads IN SERIES with the load of
which the current is to be measured.
4. Activate the device or circuit to be measured. The current value will appear on the
display.
4.5. RESISTANCE MEASUREMENTS
1. Connect the red test lead to the "VŸP$ MDFN DQG WKH EODFN OHDG WR WKH &20 MDFN
2. Place the RANGE switch in the appropriate Ÿ SRVLWLRQ
3. If the resistance to be measured is connected to a circuit : disconnect the power and
discharge all capacitors prior to measurement.
4. Connect the test leads to the circuit to be measured.
5. The resistance value will be displayed.
4.6. DIODE MEASUREMENTS
1. Connect the red test lead to the "VŸP$ MDFN DQG WKH EODFN OHDG WR WKH &20 MDFN
2. Set the RANGE switch to the
3. Connect the red test lead to the anode and the black test lead to the cathode of the
diode to be measured.
4. The forward voltage drop will be displayed in mV. "1" will be displayed if the polarity of
the diode is reversed.
4.7. TRANSISTOR hFE-MEASUREMENTS
1. Set the RANGE switch to the hFE-position.
2. Determine whether the transistor is NPN or PNP and locate the emitter, base and
collector leads. Insert the leads into the proper holes of the hFE-socket on the front
panel.
3. The display will show the approximate hFE-value at the moment of testing. Base current
10µA, Vce 2.8V.
