GENERAL SAFETY

Prior to using the multimeter, please read the product manual and ensure you have a solid

understanding of the multimeter’s functions and features.

WARNING

The warnings, cautions, and instructions discussed in this instruction

manual cannot cover all possible conditions or situations that could

occur. It must be understood by the operator that common sense and

caution are factors that cannot be built into this product, this must be

supplied by the operator.

SAFETY INSTRUCTIONS

SAFETY STANDARDS

•CAT III 600V, CAT II 1000V, double insulation and material pollution grade II.

•CAT safety level: Category III is suitable for measuring circuits connected to the power

distribution section of a buildings low voltage supply unit.

SAFETY INSTRUCTIONS

•Before using the meter inspect the case. Do not use the meter if it is damaged or the case

(or part of the case) is removed. If you can identify cracks or missing parts stop using the

meter immediately.

•Inspect the test leads for damaged insulation or exposed wires. Check test leads

continuity. Replace damaged test leads with leads that are suitable to the meter that meet

or exceed the safety requirements.

•Comply with local and national safety codes. Use personal protective equipment

(approved rubber gloves, face protection, and ame-resistant clothes) to prevent shock

and arc blast injury where hazardous live conductors are exposed.

•Do not apply more than the rated voltage, as marked on the meter, between the terminals

or between any terminal and grounding.

•Limit operation to the specied measurement category, voltage, or amperage ratings.

•Use Product-approved measurement category (CAT), voltage, and amperage rated

accessories (probes, test leads, and adapters) for all measurements.

•Use the correct terminals, function, and range for measurements.

•Before each use, verify meter operation by measuring a known voltage rst.

•Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.

•Do not use the meter around explosive gas, vapor, or in damp or wet environments

•The function selector should be placed in the right position before using the unit, do

not change the range/function during measurement to avoid damage to the meter or

equipment under test.

•When the meter is working at an eective voltage over 60V in DC or 30V rms in AC, special

care should be taken as there is danger of electric shock.

•Do not touch the probes to a voltage source when the test leads are connected to the

current terminals.

5OPERATING MANUAL

•Connect the common test lead before the live test lead and remove the live test lead

before the common test lead.

•Do not use a current measurement as an indication that a circuit is safe to touch. A voltage

measurement is necessary to know if a circuit is hazardous.

•Do not use the HOLD function to measure unknown potentials. When HOLD is turned on,

the display does not change when a dierent potential is measured.

•When using the test leads, ensure leads are fully seated and keep your ngers behind the

nger guards.

•To avoid electric shock, injury, or damage to the meter, disconnect circuit power and

discharge all high-voltage capacitors before testing resistance, continuity, diodes, or

capacitance.

•Before measuring current, check the meters fuses’and turn o the current to be tested

before connecting the meter to the circuit. After connecting the circuit reliably, turn the

current to be tested on.

•Replace the battery as soon as the battery indicator “ ” appears. With a low battery,

the meter may produce false readings that can lead to electric shock and personal injury.

•Do not alter the meter and use only as specied, or the protection supplied by the meter

can be compromised.

•Use a soft cloth and mild detergent should to clean the surface of the meter when

performing general maintenance. No abrasives or solvents should be used in cleaning;

this is to prevent the surface of the meter from corrosion, damage and accident.

•Turn the meter o when it is not in use. Remove the batteries if the meter is not used for

an extended period of time. If the batteries are not removed, battery leakage may result.

•Repair the meter before use if the battery leaks. Battery leakage may create a shock hazard

or damage the meter.

OPERATING INSTRUCTIONS

If the battery voltage is low when the device is turned on, “ ”symbol will appear on the

screen. User needs to replace batteries in time before use.

Please also pay special attention to the warning sign “ “ beside the test lead terminals, which

indicates that the tested voltage or current must not exceed the values listed on the device.

SLEEP MODE AND AUTO POWER OFF

If there is no operation for 15 minutes, the meter will automatically shut down to save power.

Before the auto shut-down, the buzzer will make ve consecutive beeps and one long beep

and then enter the sleep state. Pressing any button to exit sleep mode, and the buzzer will beep

once. To disable auto shut-down, switch the function dial to OFF position, long press SEL/REL

button and turn on the meter, the symbol disappears on the LCD with three beeps. Restart

the meter to restore the Auto-o function.

BUZZER WARNING

Input AC/DC voltage >1000V: buzzer warning and red indicator is on, high voltage symbol

appears, indicating that the range is at its limit.

• Current >10A: buzzer warning and the red indicator is on, indicating that the measured

current is relatively large, and the measurement time should be controlled.

• Low battery detection: when the battery is lower than about 4.5V±0.1V, the low battery

symbol “ “ appears.

DC VOLTAGE MEASUREMENT

1. Switch the function selector to Vposition (range: 600mV/6V/60V/600V/1000V).

2. Connect the common test lead to COM terminal, then insert the red test lead into the to

V Ω°C

terminal.
