Safety Information

Always observe safety precautions when using electrical testing equipment. Failure to do so may result in injury or damage to the meter or equipment under test.

• Do not apply voltage to the meter that exceeds the maximum rated input values for any range.
• Use extreme caution when working with voltages above 60V DC or 30V AC RMS. These voltages pose a shock hazard.
• Always disconnect the test leads from the circuit before changing functions or ranges.
• Ensure the meter is in good working condition before use. Do not use if the meter or test leads appear damaged.
• Do not operate the meter in explosive gas, vapor, or dust environments.
• Always use the correct terminals, function, and range for your measurements.

Setup and Battery Installation

Before first use, or when the low battery indicator appears, install or replace the battery.

1. Ensure the multimeter is turned OFF and disconnect all test leads from the input terminals.
2. Locate the battery compartment cover on the back of the unit.
3. Unscrew the retaining screw(s) and remove the battery compartment cover.
4. Insert a new 9V battery (NEDA 1604 or equivalent) into the battery clips, observing correct polarity.
5. Replace the battery compartment cover and secure it with the screw(s).

Note: Battery is not included with the multimeter.

Operating Instructions

Connecting Test Leads:

• Insert the black test lead into the COM (common) jack.
• For voltage, resistance, and diode measurements, insert the red test lead into the VΩmA jack.
• For current measurements up to 200mA, use the VΩmA jack.
• For current measurements up to 10A, insert the red test lead into the 10ADC jack.

Making Measurements:

Always select the appropriate function and range using the rotary switch before connecting the test leads to the circuit.

1. DC Voltage Measurement (V=):

1. Set the rotary switch to the desired DC Voltage range (e.g., 200mV, 2V, 20V, 200V, 600V).
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 on the LCD display.

2. AC Voltage Measurement (V~):

1. Set the rotary switch to the desired AC Voltage range (e.g., 200V, 600V).
2. Connect the test leads across the AC voltage source.
3. Read the voltage value on the LCD display.

3. DC Current Measurement (A=):

1. Set the rotary switch to the desired DC Current range (e.g., 200µA, 2mA, 20mA, 200mA, 10A).
2. Important: For 10A measurements, move the red test lead to the 10ADC jack. For other current ranges, use the VΩmA jack.
3. Connect the meter in series with the circuit where current is to be measured.
4. Read the current value on the LCD display.

4. Resistance Measurement (Ω):

1. Set the rotary switch to the desired Resistance range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
2. Ensure the circuit is de-energized before measuring resistance.
3. Connect the test leads across the component to be measured.
4. Read the resistance value on the LCD display.

5. Diode Test:

1. Set the rotary switch to the Diode symbol.
2. Connect the red test lead to the anode and the black test lead to the cathode of the diode.
3. The display will show the forward voltage drop. Reverse the leads; an open circuit (OL) indicates a good diode.

6. Transistor (hFE) Test:

1. Set the rotary switch to the hFE position.
2. Identify if the transistor is NPN or PNP.
3. Insert the transistor leads (E, B, C) into the corresponding holes in the hFE socket on the meter.
4. Read the hFE value on the display.

7. Data Hold Function:

• Press the "HOLD" button to freeze the current reading on the display.
• Press the "HOLD" button again to release the reading and return to live measurement.

8. Backlight Function:

• Press the "BACK LIGHT" button to turn on the display backlight for better visibility in low-light conditions.
• Press the "BACK LIGHT" button again to turn off the backlight.

Maintenance and Care

• Cleaning: Wipe the meter with a damp cloth and mild detergent. Do not use abrasives or solvents.
• Battery Replacement: Replace the 9V battery when the low battery indicator appears on the display. Refer to the "Setup and Battery Installation" section.
• Storage: If the meter is not to be used for a long period, remove the battery to prevent leakage. Store in a cool, dry place.
• Fuse Replacement: The 10A input is unfused. The mA input is fused. If the mA current range stops working, the fuse may need replacement. This typically requires opening the case and replacing a fast-blow fuse (e.g., F200mA/250V). Consult a qualified technician if unsure.
