Frequently Asked Questions - MUL-030 Steren
How do I measure DC voltage with the MUL-030?
Set the rotary switch to the appropriate DC voltage range (200mV to 600V). Connect the red lead to the VΩmA jack and the black lead to COM. Touch the probes to the circuit in parallel. Read the voltage on the display.
How do I measure AC voltage?
Turn the dial to the AC voltage setting (600V only). Insert the leads as for DC voltage. The meter displays the RMS value.
How do I test continuity?
Set the dial to the continuity/ diode position (usually marked with a sound wave icon). Connect the leads. If the resistance is less than about 100Ω, the buzzer will sound continuously.
How do I replace the battery?
Disconnect the test leads and turn off the meter. Remove the battery compartment screw on the back. Replace the 9V battery with a new one, ensuring correct polarity. Replace the cover and screw.
What is the maximum voltage this multimeter can measure?
The MUL-030 can measure up to 600V DC and 600V AC RMS. Do not exceed this limit to avoid damage or injury.
How do I measure current?
For currents up to 200mA, use the mA jack; for up to 10A, use the 10A jack. Set the dial to the appropriate DC or AC current range. Connect the meter in series with the circuit.
Does the MUL-030 have an auto-ranging feature?
No, the MUL-030 is a manual-ranging multimeter. You must select the correct range for the measurement.
What safety precautions should I take?
Always start with the highest range when measuring unknown voltages. Do not measure voltage or current beyond the rated maximum. Use the correct input jacks and settings. Inspect test leads for damage before use.
How do I test a diode?
Set the dial to the diode test position. Connect the red lead to the anode and black to the cathode. The display shows the forward voltage drop. Reverse the leads; a good diode shows 'OL' for open circuit.
How do I measure resistance?
Set the dial to the desired resistance range (Ω). Ensure the circuit is de-energized. Connect the leads across the component. Read the resistance value on the display.
