Safety Information

General Safety Requirements

Be sure to read the safety information before using this product.

Before any operations, please read the following safety precautions to avoid any possible bodily injury and prevent damage to this product or any other products connected. To avoid any contingent danger, use this product only as specified.

• Limit operation to the specified measurement category, voltage, or amperage ratings.
• Do not use the multimeter if it is damaged. Before you use the multimeter, inspect the case. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors.
• Do not use the test leads provided for other products. Use only the certified test leads specified for this product.
• Inspect the test leads for damaged insulation or exposed metal.
• Before use, verify the multimeter's operation by measuring a known voltage.
• Only qualified technicians can implement the maintenance.
• Always use the specified battery type. The power for the multimeter is supplied with a battery. Observe the correct polarity markings before you insert the batteries to ensure proper insertion of the batteries in the multimeter.
• Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings and markers of this product. Refer to the user's manual for more information about ratings before connecting to the multimeter.
• Do not operate the multimeter with the cover or portions of the cover removed or loosened.
• Do not operate if in any doubt. If you suspect damage occurs to the multimeter, have it inspected by qualified service personnel before further operations.
• Do not operate this product in wet or damp conditions.
• Do not operate in an explosive atmosphere.
• Keep product surfaces clean and dry.
• Do not apply more than the rated voltage (as marked on the multimeter) between terminals, or between terminal and earth ground.
• When measuring current, turn off the circuit power before connecting the multimeter in the circuit. Remember to place the multimeter in series with the circuit.
• When servicing the multimeter, use only the specified replacement parts.
• Use caution when working above 60 V DC, 30 V AC RMS, or 42.4 V peak. Such voltages pose a shock hazard.
• When using the test leads, keep your fingers behind the finger guards on the test leads.
• Remove the test leads from the multimeter before you open the battery cover.
• To avoid false readings, which may lead to possible electric shock or personal injury, replace the battery as soon as the low battery indicator appears and flashes.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
• Use the proper terminals, function, and range for your measurements. When the range of the value to be measured is unknown, set the rotary switch position as the highest range, or choose the auto ranging mode. To avoid damages to the multimeter, do not exceed the maximum limits of the input values shown in the technical specification tables.
• Connect the common test lead before you connect the live test lead. When you disconnect the leads, disconnect the live test lead first.
• Before changing functions, disconnect the test leads from the circuit under test.

Measurement Category

The multimeter has a safety rating of 1000 V, CAT III and 600 V, CAT IV.

Measurement category definition

• Measurement CAT I applies to measurements performed on circuits not directly connected to the AC mains. Examples are measurements on circuits not derived from the AC mains and specially protected (internal) mains-derived circuits.
• Measurement CAT II applies to protect against transients from energy-consuming equipment supplied from the fixed installation, such as TVs, PCs, portable tools, and other household circuits.
• Measurement CAT III applies to protect against transients in equipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and lighting systems in large buildings.
• Measurement CAT IV applies to measurements performed at the source of the low-voltage installation. Examples are electricity meters and measurements on primary over current protection devices and ripple control units.

If there is damage to the instrument caused by the transportation, please keep the package. With the transportation department or our distributor responsible for this business informed about it, a repairing or replacement of the instrument will be arranged by us.

Install the Batteries

The multimeter is powered by three AAA 5V battery.

⚠️ Warning: To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the low battery indicator appears.

Before replacing the battery, turn off the meter, disconnect test leads and any connectors from any circuit under test, remove test leads from the input terminals. Use only the specified battery type.

Use the following procedure to install the batteries:

1. Ensure that the rotary switch is at the [OFF] position. Remove test leads and any connectors from the input terminals.
2. Lift the tilt stand and loosen the screws with a suitable Phillips screwdriver and remove the battery cover.
3. Observe the battery polarity indicated inside the battery compartment. Insert the batteries.
4. Place the battery cover back in its original position and tighten the screws.

⚠️ Caution: To avoid instruments being damaged from battery leakage, always remove the batteries and store them separately if the multimeter is not going to be used for a long period.

Adjusting the Tilt Stand

Pull the tilt stand outward to its maximum reach (about 85° to the meter body).

Power On/Off

1. To power ON the multimeter, turn the rotary switch to any other position except [OFF].
2. To power OFF the multimeter, turn the rotary switch to the [OFF] position.

Sleep Mode

You can set the sleep time by yourself. If you do not move the rotary switch or any key within the preset time, the multimeter will automatically shut down and enter the sleep state to save battery power.

Pressing [SELECT] or turning the rotary switch will turn the multimeter back to operation mode from the sleep mode.

One minute before Auto Power-off, the buzzer will beep five times to warn. Before shutoff, the buzzer will emit a long beep, and then the multimeter will shut off.

Note: In sleep mode, the multimeter will still consume a little power. If the multimeter is not going to be used for a long period, the power should be turned off.

Flashlight

Pressing [flashlight button] to open flashlight menu. When press F1 to select TORCH to turn on/off both the front and back flashlights. When press F2 to select FRONT to turn on/off the front flashlight. When press F3 to select BACK to turn on/off the back flashlight. Press F4 to select EXIT or other functional measures to exit flashlight menu.

Low impedance (Only for V-voltage scale)

This function may only be used for voltages of a max. of 1,000 V and a max. of 3 seconds!

This function enables reducing the measuring impedance from 10 MΩ to 400 kΩ in the voltage measuring range. Through the reduction of the measuring impedance, possible phantom voltages are suppressed, which could falsify the measuring result. Press this button [LoZ button] during voltage measurement (max. 1,000 V!) for a max. of 3 seconds. After release, the multimeter has the normal measuring impedance of 10 MΩ. While the button is pressed, a signal sounds and the display “LoZ” appears.

Input terminals

The terminal connections for the different measurement functions of the multimeter are described in the table below.
