5. Setup

5.1 Battery Installation

The Hioki 3030-10 requires two AAA batteries for operation. To install or replace batteries:

1. Ensure the multimeter is turned OFF (rotary switch set to 'OFF').
2. Locate the battery compartment cover on the back of the unit.
3. Open the cover and insert two AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
4. Securely close the battery compartment cover.

5.2 Test Lead Connection

Connect the detachable test leads to the multimeter:

• Insert the black test lead into the "COM" (common) input jack.
• Insert the red test lead into the "VΩmA" input jack for voltage, resistance, and current measurements.
• Ensure connections are firm before proceeding with any measurements.

6. Operating Instructions

The Hioki 3030-10 is a manual-ranging multimeter. Always select the appropriate function and range using the rotary switch before making a measurement.

6.1 DC Voltage Measurement (V)

1. Set the rotary switch to the desired DC Voltage (V) range (e.g., 0.3V, 3V, 12V, 30V, 120V, 300V, 600V). Start with the highest range if the voltage is unknown.
2. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side.
3. Read the voltage value from the appropriate DCV scale on the analog display.

6.2 AC Voltage Measurement (~V)

1. Set the rotary switch to the desired AC Voltage (~V) range (e.g., 12V, 30V, 120V, 300V, 600V). Start with the highest range if the voltage is unknown.
2. Connect the test leads across the AC voltage source.
3. Read the voltage value from the appropriate ACV scale on the analog display.

6.3 DC Current Measurement (A)

Caution: Always connect the multimeter in series with the circuit when measuring current. Never connect it in parallel across a voltage source.

1. Set the rotary switch to the desired DC Current (A) range (e.g., 60µA, 30mA, 300mA). Start with the highest range if the current is unknown.
2. Break the circuit and connect the multimeter in series, ensuring the current flows through the meter.
3. Read the current value from the appropriate DCA scale on the analog display.

6.4 Resistance Measurement (Ω)

Caution: Ensure the circuit is de-energized before measuring resistance.

1. Set the rotary switch to the desired Resistance (Ω) range (e.g., x1, x10, x100, x1k).
2. Before measuring, short the test leads together and adjust the "Ω ADJ" knob (if present) to zero the meter.
3. Connect the test leads across the component to be measured.
4. Read the resistance value from the Ω scale on the analog display and multiply by the selected range multiplier.

6.5 Battery Test (BATT 1.5V)

1. Set the rotary switch to the "BATT 1.5V" position.
2. Connect the red test lead to the positive (+) terminal of the 1.5V battery and the black test lead to the negative (-) terminal.
3. Read the battery charge level from the "BATT" scale on the analog display.

6.6 LED Test (LED)

1. Set the rotary switch to the "LED" position.
2. Connect the test leads to the LED. Observe polarity; if the LED does not light, reverse the leads.
3. A lit LED indicates functionality.

6.7 Temperature Measurement (TEMP)

This function requires a separately purchased thermistor probe. Refer to the thermistor probe's manual for specific connection and operation instructions.

1. Set the rotary switch to the "TEMP" position.
2. Connect the thermistor probe to the designated input jacks.
3. Read the temperature from the "TEMP(°C)" scale on the analog display.

7. Maintenance

7.1 Cleaning

Wipe the meter casing with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is off and disconnected from all circuits before cleaning.

7.2 Fuse Replacement

If the current measurement function ceases to operate, the fuse may need replacement. The Hioki 3030-10 uses a 0.5-amp/250V fuse. Always replace with a fuse of the identical type and rating.

1. Ensure the multimeter is turned OFF and test leads are disconnected.
2. Refer to the device's internal diagram (if available) or contact customer support for instructions on accessing the fuse compartment.
3. Carefully remove the old fuse and insert the new 0.5A/250V fuse.
4. Reassemble the meter securely.

7.3 Storage

When not in use, store the multimeter in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.

8. Troubleshooting

If the multimeter does not function as expected, consider the following:

• No Display/Power: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• Incorrect Readings:
  • Ensure the correct function and range are selected for the measurement.
  • Verify test leads are properly connected and not damaged.
  • For resistance measurements, ensure the circuit is de-energized and the meter is zeroed.
• Current Function Not Working: Check the internal fuse (refer to Section 7.2).
• Needle Not Moving: Ensure the meter is powered on and the test leads are making good contact with the circuit. Check for open circuits.

If problems persist after attempting these steps, contact Hioki customer support for further assistance.
