Frequently Asked Questions - MUL-110 Steren

How do I measure DC voltage with the MUL-110?

Set the rotary switch to the DCV range (200mV, 2V, 20V, 200V, or 600V). Connect the black test lead to COM and red to VΩmA. Touch the probes to the circuit. Read the display.

What type of battery does the MUL-110 use?

It uses a 9V battery (6F22 or equivalent). Replace it when the low battery symbol appears.

How do I measure resistance?

Turn the dial to the Ω range. Connect leads to COM and VΩmA. Ensure the circuit is de-energized. Touch probes to the resistor and read the value.

Does the MUL-110 have a continuity test?

Yes, set the dial to the continuity (diode/continuity) position. The buzzer will sound if the resistance is below about 50Ω.

Can I measure AC current with this multimeter?

Yes, select the ACA range (200µA to 10A). For currents above 200mA, use the 10A input jack (red lead). Note: it may be fused.

What is the maximum voltage I can measure?

The MUL-110 can measure up to 600V DC or AC (CAT II). Do not exceed this rating to avoid damage or injury.

How do I replace the fuse?

Disconnect test leads, open the battery compartment cover. Locate the fuse (usually 10A/250V). Replace with same type. Ensure the meter is off.

Why does the display show '1' or 'OL'?

This means overload or the reading is out of range. Select a higher range or check if the test leads are properly connected.

How do I clean the multimeter?

Use a soft, dry cloth to wipe the case and display. Do not use water, solvents, or abrasives.

What does the auto power off feature do?

The meter automatically shuts off after about 15 minutes of inactivity to conserve battery. Turn the dial to wake it up.

CAUTIONS

• To avoid shock hazard, do the high voltage measures, carefully.
• Always disconnect the tested circuit before connecting testing leads.
- Before to use the range switch, disconnect the testing leads.
- Never operate this multimeter over the maximal indicated tolerance
- When you use this multimeter on TV sets or interrupted power circuits, could have voltage pulses with high amplitudes and may cause damages on the ammeter.
- Be careful when you manage with high voltages around 60VDC (V=) or 30 VAC RMS (V-).
- Keep the fingers in back of the test barriers, during measuring.
- Unplug the test leads from all the electrical current before to open the ammeter.
- Never use the ammeter if the battery cover is not placed correctly.
- Only clean with a soft, damp cloth.

HIGHLIGHTS

• The auto range hook multi-tester has an ergonomic design.
- The ampere-meter function - using the hook- is very accurate and free of risks, with it you don't require to peel the cable to measure.
- It can perform measuring of resistances, diodes, AC and DC voltage, AC amperage, and continuity. - Very useful for students, technicians and engineers.
- It has a luminous display, hold, maximum value and auto range.
• Auto range.
• Audible continuity.
- Hold.
• Maximum value.
• Light for the hook and screen.

CONTROLS

1. Hook: it measures the magnetic field of a cable.
2. Hook button: Opens or closes the arms of the hook.
3. Select knob: select ranges and functions to be carried out.
4. [★]: Press and hold to switch on the illumination of the display. In current measurement light, at the same time, the auxiliary light.
5. SEL: Select different measurements.
6. MAX: Shows the maximum value of the measurement.
7. RAN: It selects the range manually. Leave it pressed to return to the automatic selection.
8. HOLD: Holds the measuring data.
9. LCD screen.
10. Inputs: Connect the measuring leads.

MEASUREMENTS

Hook arms

Place the current-carrying conductor (A\~) in the middle of the arms of the hook by pressing the hook button to open and releasing it to close it.

Inputs

This device has two entries that are protected against overload. During use connect the black measuring lead into the COM jack and the red lead to the INPUT one.

If you want to keep a measure on the screen for easy reading, press the HOLD button. Press once more to return to the measurement screen.

Current measurement

1. Turn the selector knob to the desired A\~ position. Hook arms will measure the amps of AC (\~) that circulate through the conductor.
2. When "0.L" appears on the LCD, it means that there is a situation of overload. Select a higher range.

Voltage measurement

1. Place the selector knob on the V range and connect the measuring leads.
2. Press the SEL button to select voltage of direct (DC) or alternating (AC) current.
3. When "0.L" appears on the LCD, it means that there is a situation of overload.

Resistance measurement

1. Place the selector knob on the Ω position and connect the measuring leads.
   If the resistance being measured exceeds the maximum possible value, "0.L" will be displayed on the LCD.
2. When making a resistance measurement in circuits, be careful that these are without power and capacitors are fully discharged.

Diode measurement

To prevent electrical shock and/or equipment damage, disconnect the circuits and discharge capacitors with high voltage before making measurements of diodes.

1. Set the selector knob in the range.
2. Press the SEL button to activate the diode test mode.
3. Will appear on screen.
4. The meter will show the approximate voltage of the diode.

Continuity measurement

1. Place the selector knob in the position
2. Press the SEL button to activate the function of continuity.
3. will appear on screen.
4. When the measurement result is less than 25 Ω, a continuous tone will sound.

BATTERY REPLACEMENT

If the symbol "☐" appears on the LCD, the battery should be replaced with a new one.

1. Make sure that measurement probes are unplugged to prevent electric shock.
2. Open the battery compartment using a screwdriver and place 3 new AAA batteries. Be careful with the polarity, since it can cause permanent damage to the equipment.
3. Replace the compartment cover.
4. Turn on the meter.
