Using Your Cen Tech Digital Multimeter
Once you have set up your multimeter, you can start using it for various measurements. Here’s a guide to performing common tasks:
Measuring Voltage
To measure voltage (either AC or DC):
1. Turn the function selector to the appropriate voltage setting (V~ for AC or V— for DC).
2. Insert the black test lead into the COM port and the red test lead into the VΩmA port.
3. Touch the black lead to the negative side and the red lead to the positive side of the circuit.
4. Read the voltage on the display.
Measuring Current
To measure current:
1. Set the function selector to the appropriate current setting (A~ for AC or A— for DC).
2. Connect the test leads as described above.
3. Break the circuit where you want to measure the current and connect the multimeter in series.
4. Read the current on the display.
Measuring Resistance
To measure resistance:
1. Turn the function selector to the resistance setting (Ω).
2. Connect the test leads as usual.
3. Touch the leads to the resistor or component you wish to measure.
4. Read the resistance value on the display.
Additional Functions
Your Cen Tech multimeter may have other functions like:
- Continuity Testing: To check if a circuit is complete.
- Capacitance Measurement: For measuring capacitors, if supported.
- Diode Testing: To check the function of diodes.
Refer to the user manual for specific instructions on each function.
Safety Precautions
When using your Cen Tech digital multimeter, safety should always be a priority. Follow these precautions:
- Always start with the highest voltage setting to avoid damaging the multimeter.
