Safety information

• Before use, make sure that all accessories are in the package and undamaged. The meter is designed in accordance with IEC61010 (safety standard issued by the International Electrotechnical Commission or equivalent GB4793.1). Please read the safety notes before use.
• Only take measurements in the measuring range! Do not use in a larger range!
• If you measure voltage higher than 36 V DC or 25 V AC, check the connection and insulation of the test leads to avoid electric shock.
• When changing the measurement mode (functions) and range, the measuring tips must be removed from the test point.
• Before measuring, always make sure that you are measuring a voltage that corresponds to the measurement limit.
• Before changing batteries or fuses, always remove the measuring tips from the measuring point and switch off the device.
• Do not operate the device if the battery or battery cover is not properly attached!
• Only measure capacitance, diode or continuity on a deenergized circuit
• Please comply with the local and national safety regulations: During the measurement, if necessary, wear personal protective equipment (gloves, face mask, flame-resistant clothing) to avoid injuries from electric shock and arcing.
• Only measure according to the appropriate Standard Measurement Category (CAT). (voltage probe, test lead and adapter)

Modes

Resistance measurement:

Select the resistance measurement function “Ω”. Connect the red banana plug to the “INPUT” jack and the black banana plug to the “COM” jack. Touch the probes to the circuit to be measured. The measured value appears on the display. During measurement, the circuit must be free of voltage, check this in every case.
Tensile test:

Select the tear test function “ Connect the red banana plug to the “INPUT” jack and the black banana plug to the “COM” jack. Touch the probes to the circuit to be measured. The measured resistance value appears on the display, if it is below 50 Ω, the instrument emits a beeping sound and the indicator LED lights up. During measurement, the circuit must be free of voltage, check this in every case.

Diode test:

Select the diode test function „ Connect the red banana plug to the “INPUT” jack and the black banana plug to the “COM” jack. Touch the test tips to the diode to be tested, red is the anode, black is the cathode when measuring in the open direction. The displayed value is the forward voltage of the diode. In the event of a break or closing direction, „OL” appears on the display.

Capacity measurement:

Select the capacity measurement function „ Connect the red banana plug to the “INPUT” jack and the black banana plug to the “COM” jack. Touch the probes to the circuit to be measured. Before measuring, the capacitors must be discharged in any case, in order to avoid the failure of the instrument. The instrument may need several seconds to measure larger capacity capacitors

Frequency and duty cycle measurement:

Select the frequency measurement function „ Connect the red banana plug to the “INPUT” jack and the black banana plug to the “COM” jack. Touch the probes to the circuit to be measured. The measured value appears on the display, the lower line shows the frequency and the upper line shows the duty cycle.
Temperature measurement:

Select the temperature measurement function „ . Connect the red banana plug of the test probe to the “INPUT” socket and the black banana plug to the “COM” socket. Touch the measuring tip to the surface to be measured. The measured value appears on the display, the bottom line shows °C (celsius) and the top one shows the temperature in °F (fahrenheit). Without connecting a measuring probe, the instrument shows the ambient temperature.

Battery and fuse replacemen

1. Remove the test leads from the instrument and the circuit under test.
2. Remove the rubber protective cover
3. Remove the battery cover screw and then remove the battery cover
4. Replace the 4 AAA batteries or, if necessary, the fuse, with a value of 10A/250V, size 5×20 ceramic fuse
5. Replace the battery holder, then the screw and rubber protective cover

  Proper disposal of the device (Electrical device) (Valid in the European Union and all other European states that participate in selective collection) According to the 2012/19/EU directives, electrical waste and devices cannot be thrown away as household waste. Old appliances must be collected in order to maximize the recycling of raw materials, thereby reducing their impact on people’s health and the environment. The crossed-out bin symbol is on all products for which separate collection is mandatory. Consumers should check with their local authorities for more information.
