2.1 General rules

In order to provide conditions for correct operation and the correctness of the obtained results, the following recommendations must be observed:

• before using the meter read carefully this manual,
• the meter should be operated only by qualified persons that have passed health and safety training,
• be very careful when measuring voltages exceeding (as per IEC 61010-1:2010/AMD1:2016):

Normal locations	Wet locations
60 V DC	35 V DC
30 V AC RMS	16 V RMS
42.4 V AC of peak value	22.6 V AC of peak value

as they generate a potential risk of electric shock,

• do not exceed the maximum limits of the input signal,
• during the voltage measurements do not switch the device in the current or resistance measuring mode and vice versa,
• when changing ranges, always disconnect the test leads from the tested circuit,
• hold the measuring probes by the spot provided, restricted by a special barrier to avoid accidental contact with exposed metal parts,
• If during the measurement symbol OL appears on the screen, it indicates that the measured value exceeds the measurement range,
• It is unacceptable to operate:

⇒ a damaged meter which is completely or partially out of order,
⇒ a device with damaged insulation of test leads,
⇒ a meter stored for an excessive period of time in disadvantageous conditions (e.g. excessive humidity).

- repairs may be carried out only by an authorised service point.

WARNING

• Never start the measurements if you have wet or damp hands.
• Do not perform measurements in explosive atmosphere (e.g. in the presence of flammable gases, vapours, dusts, etc.). Using the meter in such conditions may result in sparking and cause an explosion.

2.2 Safety symbols

This symbol located near another symbol or terminal, indicates that the user should read the further information contained in the manual.

This symbol located near the terminal, indicates that in normal use there is a possibility of dangerous voltages.

Protection class II – double insulation

Terminals with this marking cannot be connected to a circuit where the voltage to ground exceeds the maximum safe voltage of the device.

3 Preparing the meter for operation

After purchasing the meter, check whether the content of the package is complete.

Before performing the measurement:

• make sure that the battery level is sufficient for measurements,
• check whether the meter casing and insulation of the test leads are not damaged,
• to ensure consistent measurement results it is recommended to connect black lead to COM terminal and red lead to other terminals,
• when the meter is not in use, set the function switch in OFF position.

The device has the AUTO-OFF function triggered after 30 minutes of user inactivity. To turn the meter on again, set the function switch to OFF position and then set it at the desired function.

WARNING

• Connecting wrong or damaged leads may cause electric shock.
• The meter must not be connected to the voltage source when it is set to current or resistance measurement or to diode test. Failure to observe this precaution may damage the meter!

When using the meter, be sure to:

• discharge capacitors in the tested power sources,
- disconnect the power supply when measuring the resistance and diode tests,
- turn off the meter and disconnect test leads before removing the back cover to replace the batteries.

WARNING

Do not use the meter if the cover of battery compartment is removed.

It is possible that in certain low ranges of AC or DC voltage, when the meter is not connected to the leads, the screen will show random and variable readings. This is a normal phenomenon, which results from the input sensitivity with high input resistance. When connected to a circuit, the read-out will stabilize and the meter will provide the correct value.

5 Measurements

The content of this chapter should be thoroughly read and understood since it describes methods of measurements and basic principles of interpreting measurement results.

5.1 Current measurement

WARNING

Disconnect the test leads before measuring current using clamp.

To perform the current measurement:

• set the rotary switch at 600A ≈ / 1000A ≈,
• press MODE/INRUSH button to display the following symbol:

⇒ , if you are measuring alternating current, ⇒ , if you are measuring direct current,

- use the clamp-opening trigger and attach the clamps on the tested conduit. Only one conduit must be within the testing range of the clamps,

- read the measurement result on the display.

If DC current is measured and the meter is not attached to the tested circuit, but it still indicates a non-zero value, then you must reset it by pressing and holding REL button.

5.2 Non-contact voltage detector

WARNING

• The detector is designed to detect the presence of a voltage, not for determining its absence.
• Electric shock hazard. Before using the tester, check if its operational by testing it on a known AC voltage (i.e. next applicable socket with live voltages).

To activate the detector:

• set the rotary switch at any position,
• touch the tip of the detector to the tested object.
  If the AC voltage is present, the indicator light will glow red.

• The wires in the extension cords are often twisted. For best results, move the tip of the detector along the wire to locate the live line.
• The indicator has a high sensitivity. It can be randomly actuated by static electricity or other energy sources. This is normal.
• The type and thickness of the insulation, distance from the power source, shielded cables and other factors may affect the operation of the tester. If you are unsure about the test result, check the presence of voltage in a different way.

5.3 Voltage measurement

WARNING

• Electric shock hazard. The ends of measuring probes, due to their length, may not reach the live parts inside some network connections of low-voltage electrical equipment, because the contacts are arranged inside the sockets. In such a case, the read-out will be 0 V with the simultaneous presence of voltage in the socket.
• Before acknowledging the absence of voltage in the socket make sure that the ends of the probe touch the metal contacts inside the socket.

CAUTION!

Do not measure the voltage when an electric motor located within the circuit is being switched on or off. Resulting voltage spikes may damage the meter.

To perform AC voltage measurement:

• set the rotary switch at (direct voltage) or Hz% (alternating voltage),
• connect black test lead to COM terminal, and red test lead to V Hz% -CAPTemp terminal,
• contact the tips of test probes to the points of measurement,
• read the measurement result on the display.

5.4 Frequency measurement

To perform frequency measurement:

• set the rotary switch at Hz% or LoZ Hz%,
• press MODE/INRUSH button to display Hz on the screen,
• connect black test lead to COM terminal, and red test lead to
  VΩHz% -CAPTemp terminal,
• contact the tips of test probes to the points of measurement.
• read the measurement result on the display.

5.5 Measurement % of duty cycle (pulse filling indicator)

To perform the measurement:

• set the rotary switch at % or LoZ % .
• press MODE/INRUSH button, until symbol % is shown on the display.
• connect black test lead to COM terminal, and red test lead to

VΩHz% -CAPTemp terminal,

• contact the tips of test probes to the points of measurement.
• read the measurement result on the display.

5.6 LoZ measurement (elimination of interference and induced voltages)

Measurement function in 'LoZ' mode eliminates the influence or interference voltages or induced voltages, making the measurement more accurate and reliable. These voltages may occur due to capacitive feedback between the live conductors and the unused conductors located in the vicinity:

• set the rotary switch at LoZ VHz%
• press MODE/INRUSH button to display the following symbol:
  V AC – if you are measuring alternating voltage,
  Hz – if you are measuring frequency,
  ⇒ % – if you are measuring duty cycle,

- connect black test lead to COM terminal, and red test lead to V Hz% -CAPTemp,

- contact probe blades to measurement points,

- read the measurement result on the display.

5.7 Measurement of resistance

WARNING

Do not perform measurements on the circuit under the voltage. Before the measurement disconnect the power and discharge capacitors.

To perform measurement of resistance:

• set the rotary switch at • CAP,
• connect black test lead to COM terminal, and red test lead to V Hz% -CAPTemp terminal,
• contact the tips of test probes to the points of measurement; the best solution is to disconnect one side of the tested element, to prevent the remaining part of the circuit interfere with the read-out of the resistance value,
• read the measurement result on the display.

5.8 Circuit continuity test

WARNING

Do not perform measurements on the circuit under the voltage. Before the measurement disconnect the power and discharge capacitors.

To perform the continuity test:

• set the rotary switch at • CAP,
• press MODE/INRUSH button to display ⚪Ω on the screen,
• connect black test lead to COM terminal, and red test lead to V Hz% CAPTemp terminal,
• contact the tips of test probes to the points of measurement,
• read the measurement result on the display; the beep will be activated when resistance values are below approx. 50 Ω.

5.9 Diode test

WARNING

Do not perform measurements on the circuit under the voltage. Before the measurement disconnect the power and discharge capacitors. Do not test the diode under voltage.

To perform the diode test:

• set the rotary switch at - CAP,
• press MODE/INRUSH button, to display ▶ V on the screen,
• connect black test lead to COM terminal, and red test lead to V Hz% -CAPTemp terminal,
• contact the tips of test probes to the diode. The red test probe should contact the anode and the black should contact cathode,
• read the test result on the display – the forward voltage is displayed.
  ⇒ For a typical silicon rectifier diode, it is approx. 0.7 V, and for a germanium diode it is approx. 0.3 V

⇒ For LEDs with a low power, typical voltage value is in the range of 1.2...5.0 V depending on the colour.
⇒ If the diode is polarized in the reverse direction, or there is a break in the circuit, the display will show OL.
⇒ When the diode is shorted, the meter will show a value near 0 V,

- after completing the measurements, remove test leads from the terminals of the meter.
