1. SAFETY

1.1. PRECAUTION OF USE

This instrument is compliant with safety standard IEC/EN 61010-2-033 or BS EN 61010-2-033 and the leads are compliant with IEC/EN 61010-031 or BS EN 61010-031, for voltages up to 600V in measurement category III.

Failure to observe the safety instructions may result in electric shock, fire, explosion, and destruction of the instrument and of the installations.

■ The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.

If you use this instrument other than as specified, the protection it provides may be compromised, thereby endangering you.

■ Do not use your instrument on networks of which the voltage or category exceeds those stated.

- Observe the environmental conditions of use.

■ Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.

■ Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation is deteriorated (even partially) must be set aside for repair or scrapping.

■ Use leads and accessories rated for voltages and categories at least equal to those of the instrument. If not, an accessory of a lower category lowers the category of the combined device + accessory to that of the accessory.

■ Do not use the instrument in an explosive or dust-laden atmosphere.

■ When handling the test probes, keep your fingers behind the physical guard.

■ Use caution on live circuits, Voltages above 30 VRMS, 42 Vpeak or 60 Vdc pose a shock hazard.
■ Use personal protection equipment systematically.
■ All troubleshooting and metrological checks must be done by competent, accredited personnel.

■ Press the MODE button to select AC/DC voltage, AC/DC current, frequency, resistance, diode test, continuity or capacitance, temperature.
■ Press the REL button for >2 second to turn on or off the Relative function.
■ The Relative function zeros out the reading on the display and stores it as a reference, subsequent readings will be displayed as the relative difference between the actual measurement and the stored reference value.

Note: REL does not work on Frequency, Diode Test, Continuity.

3.2. RANGE BUTTON

When the meter is first turned on, it automatically goes into Auto Ranging.

This automatically selects the best range for the measurements being made and is generally the best mode for most measurements.

For measurement situations requiring that a range be manually selected, perform the following:

■ Press the RANGE button, the AUTO display indicator will turn off.
■ Press the RANGE button to step through the available ranges until you select the range you want.
■ Press and hold the RANGE button for 2 seconds to exit the Manual Ranging mode and return to Auto Ranging.

■ Press the MODE button until the symbol appears on the LCD display.
- Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana plug into the + terminal.

■ Touch the test lead probes to the component under test, if the component is installed in a circuit, it is best to disconnect one side before testing to eliminate interference with other devices.
- Read the resistance in on the LCD display.

4.5. DIODE TEST

WARNING: Never test resistance on a live circuit.

■ Set the rotary function switch to the Ω↔CAP position.

■ Press the MODE button until the ➤ symbol appears on the LCD display.

■ Press the MODE button to indicate °C or °F.

■ Connect the temperature probe to the banana plug adapter, note the - and + markings on the adapter.

■ Connect the adapter to the meter, making sure the - side goes into the COM terminal and the positive side goes into the + terminal.

■ Touch the tip of the temperature probe to the object being measured.

- Read the temperature on the LCD display.

4.9. NON-CONTACT AC VOLTAGE DETECTION

WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit to verify proper operation.

■ Set the rotary function switch to the NCV position.

■ Hold the detector close to the AC voltage being tested.

- If no signal is detected, the LCD will show EF, NCV indicator light doesn't flashes and the buzzer is no sound. - According to the detected signal strength, LCD displays different horizontal lines.

■ When the signal is strongest, LCD displays four horizontal lines, when the signal is weakest, only one line.

■ Meanwhile, NCV indicator light flashes, buzzer make different sound.

Note: The sensing level varies with the distance between the sensing part and the measured AC power cord.

Note: The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sensor. This is normal operation.

The absence of a voltage indication in the NCV function does not mean that there is no voltage. To confirm the absence of a voltage, use a VAT.

The presence of other voltages nearby can trigger non-contact voltage detection.
