4. Read the value from the LCD.
5. When frequent capacitance testing is needed you should connect the multifunction socket (included) with the
COM & V/
Ω
/A sockets. Insert the capacitor’s pins in the “+” and “-“ connectors of the multifunction socket.
REMARKS
•
When measuring low capacities, the reading will include the capacity of the measuring leads. However, this will
not influence the accuracy of your measurements.
•
The device will need some time to produce a stable reading when measuring high capacitance values.
5.12. Inductance Measurements
1. Connect the black test lead with the COM jack and the red test lead with the H jack.
2. Place the range switch in the desired H range position and press the L/C button.
3. Connect the test leads with two points of the inductor to be tested.
4. Read the value from the LCD.
5. When frequent inductance testing is needed you should connect the multifunction socket (included) with the COM
& V/
Ω
/A sockets. Insert the inductor’s pins in the “+” and “-“connectors of the multifunction socket.
REMARKS
Keep in mind that precise inductance measurements are impossible in close vicinity to strong magnetic fields.
5.13. Temperature Measurements
WARNING
Do not connect the thermocouples with electrical circuits in order to avoid electroshocks.
1. Put the range switch in the °C-range position.
2. The LCD displays the current environmental temperature.
3. Insert “K”-type thermocouples into the COM jack and V/
Ω
/A jack (or you can use the multifunction socket to
connect a different type of K-thermocouple).
4. Read the value from the LCD.
5.14. Frequency Measurements
1. Connect the black test lead with the COM jack and the red test lead with the Hz jack.
2. Place the range switch in the 20KHz range position.
3. Connect the test leads with the source or load to be tested.
4. Read the value from the LCD.
REMARKS
•
It is possible to obtain a reading with input voltages above 10Vrms, but the accuracy is not guaranteed.
•
Use shielded cable to measure small signals in a noisy environment.
