2. Safety Information

To ensure safe operation, always adhere to the following safety precautions:

• Do not exceed the maximum input values specified for each measurement range.
• Ensure test leads are properly connected and in good condition before each use.
• Do not use the multimeter if it appears damaged or if the battery cover is not securely closed.
• Exercise caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC, as these pose a shock hazard.
• Always disconnect power to the circuit and discharge high-voltage capacitors before measuring resistance, continuity, diodes, or capacitance.
• Replace batteries promptly when the low battery indicator appears to ensure accurate readings.

4. Setup

4.1 Battery Installation

The multimeter requires two AAA batteries for operation.

1. Ensure the multimeter is powered off.
2. Locate the battery compartment on the rear of the device.
3. Open the battery compartment cover.
4. Insert two AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Securely close the battery compartment cover.

4.2 Test Lead Connection

Connect the test leads to the appropriate input jacks:

• Insert the black test lead into the COM (Common) jack.
• Insert the red test lead into the VΩHz jack for voltage, resistance, frequency, capacitance, and diode measurements.
• For current measurements (mA/A), insert the red test lead into the 10A MAX or mAμA jack as appropriate for the expected current level.

5. Operating Instructions

5.1 Power On/Off

Rotate the central function dial from the OFF position to any desired measurement function to power on the multimeter. To power off, rotate the dial back to the OFF position.

5.2 Function Selection

The DLY-0801B features both manual and auto-ranging capabilities. Rotate the central dial to select the desired measurement function (e.g., V for voltage, Ω for resistance, A for current, Hz for frequency, NCV for non-contact voltage). The multimeter will typically default to auto-ranging within the selected function.

5.3 Taking Measurements

General Measurement Steps:

1. Connect the test leads correctly as described in Section 4.2.
2. Rotate the function dial to the desired measurement mode.
3. Apply the test leads to the circuit or component under test.
4. Read the measurement value on the display.

Specific Measurement Modes:

• Voltage (AC/DC): Select 'V~' for AC voltage or 'V=' for DC voltage. Connect leads in parallel with the circuit.
• Current (AC/DC): Select 'A~' for AC current or 'A=' for DC current. Connect leads in series with the circuit. Ensure correct jack selection (10A MAX or mAμA).
• Resistance (Ω): Select 'Ω'. Connect leads across the component. Ensure power is off and capacitors are discharged.
• Capacitance (F): Select 'F'. Connect leads across the capacitor. Ensure capacitor is discharged.
• Frequency (Hz): Select 'Hz'. Connect leads to the signal source.
• Non-Contact Voltage (NCV): Select 'NCV'. Bring the top of the multimeter near an AC voltage source. The device will indicate voltage presence with an audible alarm and visual indicator.

5.4 Warning Indicators

• Over-range Warning: If the measured voltage or current exceeds the set alarm value, the multimeter will emit a continuous buzzer sound.
• Line On-Off Warning: When testing line continuity, the buzzer may sound if the resistance is less than 50Ω.

5.5 Automatic Shutdown

The multimeter is designed with an energy-saving feature that automatically shuts down the device after approximately 15 minutes of inactivity. This helps to conserve battery life.

6. Maintenance

6.1 Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is completely dry before use.

6.2 Battery Replacement

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use two new AAA batteries.

6.3 Fuse Replacement

If the current measurement function fails, the fuse may need replacement. Fuse replacement should only be performed by qualified personnel. Refer to the specifications for the correct fuse type and rating.

7. Troubleshooting

• No Display: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• Incorrect Readings: Verify test lead connections, ensure the correct function is selected, and check for low battery.
• Current Measurement Not Working: Check the fuse. If blown, replace with a fuse of the correct rating.
• Screen Malfunction: If parts of the screen stop working, contact customer support for assistance.
