Security Information

Warming : People who use this meter should pay special attention to it , because the improper use might cause electric shock or damage ta the meter. Please follow the actual safety rules and safety measure. To fully use the function of ttl’1s meter and ensure its safety opention.plta.se re-ad and follow- its usage methods in the specification carefully.

This meter matched the technical requirement of digital multimeter GB/T 13978-92 and the safety requirement of electronic meisuring meter GB4793.l-199S ( IEC-61010-1. It belongs to secondary pollution and its over- voltage standard is CAT ll 600V.
Please follow the safe cp1cr.ation guide and ensure safe use for this meter.
Proper use and maintenance for meter will give you a satisfied service.

Preparation

• Users must follow the standard safety ruin when using it : – Need some universal protection to avoid electric shock.
• Check if there is any damage on this meter or not in this process of transportation when received it.
• Check if there is any damage on this meter or not when preserved loaded and delivered it in poor condition.
• The test lead must be in a good condition. Chock whether there is any damage on its insulation or not and if meter’ s metal wire is exposed or not before using it.
• Don’ t touch the top of test lead (the metal part) when linked meter with measuring circuit.
• When testing, if the voltage tested is over GOV DC or 30V AC (RMS), please keep your fingers behind the test lead protector,
• When the measuring terminal voltage is over wav DC or 600V AC, please stop testing voltage
• Do not measure resistance, capacity diodes and lines when the line is energized.
• When use current;.re5f5tance,capacitor,diode and circuit breaker, user should avoid to link meter with voltage source.
• Don’t test capacitance before the cap.,citor is fully discharged.
•  Don’t use the meter under the explosive gas, steam or dust environment.
• If there is any abnormality or malfunction in the meter, user should stop using it.
• Multimeter should not be used unless the meter bottom shell and the battery cover are completely clasped  place.
• Don’t preserve or use meter in the condition of direct sunlight high temperature, high humidity.

Marks

Double insulation protection.
In accordance with the IEC-61010-l standard over-voltage (installation) level D, pollution level 2,CAT II means the level of pulse withstand voltage protection provided.

Operation Instructions

1. Voltage DC or AC/ Frequency/Resistance/Measure Continuity
2. Press the power button, the default mode is AUTO mode.
3. Connect the test lead-in parallel to the circuit, power supply, or tested resistor. The meter automat cally !dent fy whether tis AC voltage, DC voltage or resistance, and shows the frequency on the screen.
4. The built -in burr sounds if the tested resistance less than 300. Read the test results from the screen and view the dynamic changes of the values thro ugh the analog bar.

Warning:

• Do not input voltages higher than600V and currents greater than 200m showing higher voltage and Current values are possible but it may destroy the meter.
• When measuring high voltage, be careful to avoid electric shock.
• Disconnect the test leads from the circuit when completed measurement

V-Alert or Live wire check

1. Press the power button.
2. Pres; V-Alert LIVE button, switching to voltage detection mode. Voltage DC The screen displays V~Alert.
3. Close the non-contact voltage sensor of the meter to (Less than 5mm) the live tine of the AC voltage. The value bar of the meter screen lights up. The bar value shows L (low range), M (mid-range), H {high-range) according to the detected voltage strength. The higher the detected voltage strength, the higher the alarm sound frequency of the buzzer.
4. Press the V-Alert/LNE button, switching to the live Check mode and the screen displays Live.
5. Insert any test probe into the socket jack, If the meter detects AC voltage, The screen will display LlVE. and the buzzer will sound an alarm indicating that the line is a live wire.
