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.

Current measurement

WARNING:
Disconnect the test leads before measuring current using clamp.

Range of 3000 A
To perform the current measurement:

• set the rotary switch at 3000A ,
• connect flexible clamp to COM and VΩ Hz%CAPTemp sockets,
• fasten the clamp around the tested conduit. Only one conduit must be within the testing range of the clamp,
• read the measurement result on the display.

Range of 1000 A
To perform the current measurement:

• set the rotary switch at 1000A,
• press the MODE button to display the following symbol:
  • if you are measuring alternating current,
  • if you are measuring direct current,
• use the clamp-opening trigger 5 and attach the clamps to the tested conduit. Only one conduit must be within the testing range of the clamps,
• read the measurement result on the display.

If DC 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 briefly pressing the REL/Hz button.

Non-contact voltage detector

WARNING

• The detector is designed to detect the presence of a voltage, not to determine its absence.
• Electric shock hazard. Before using the tester, check if it’s 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 differently.

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 V Hz or mV,
• press the MODE button to display the following symbol:
  • if an alternating voltage is to be measured,
  • if a constant voltage is to be measured,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ Hz%CAPTemp terminal,
• contact the tips of test probes to the points of measurement,
• read the measurement result on the display.

Frequency measurement
To perform frequency measurement:

• set the rotary switch at Hz%,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ Hz%CAPTemp terminal,
• contact the tips of test probes to the points of measurement,
• read the measurement result on the display.

Measurement % of duty cycle (pulse filling indicator)

To perform the measurement:

• set the rotary switch at Hz%,
• Press the MODE button, until the symbol % is shown on the display,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ Hz%CAPTemp terminal,
• contact the tips of test probes to the points of measurement,
• read the measurement result on the display.

Measurement of resistance

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

To measure resistance:

• set the rotary switch at Ω ,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ 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 from interfering with the read-out of the resistance value,
• read the measurement result on the display.

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 Ω ,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ Hz%CAPTemp terminal,
• Press the MODE button, to display Ω on the screen,
• 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.

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 Ω ,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ Hz%CAPTemp terminal,
• Press the MODE button, to display and V on the screen,
• and contact the tips of test probes to the diode. The red test probe should contact the anode and the black should contact the 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 low power, the typical voltage value is in the range of 1.2…5.0 V depending on the color.
  • 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.

Measurement of capacitance

WARNING
Risk of electric shock. Disconnect the power supply from the tested capacitor and discharge all capacitors before any starting capacity measurements.

To perform the measurement:

• set the rotary switch at CAP,
• connect the black test lead to the COM terminal, and the red test lead to the VΩ Hz%CAPTemp terminal,
• contact the probe tips to the tested capacitor,
• read the measurement result on the display.

Temperature measurement

To perform the measurement:

• To enable the mode, press REL/Hz. Then, the displayed readout value is taken as the reference value, and the readout will be re-set.
• From this moment, the readings will be presented as the ratio of the measured value to the reference value.
• To enable the mode, press REL/Hz.

The displayed main result is the difference between the reference value (read- out at the moment of activating REL mode) and the current read-out. For example: if the reference value is 20 A, and the current reading is 12.5 A, then the main result on the display will be -7.5 A. If the new reading is identical to the reference value, then the result will be zero.

• When the function is activated, the automatic adjustment of the measuring range is not available.
• If the reading is outside the measurement range, symbol OL is displayed In this situation, turn off the function and manually switch to a higher range.
• This function is not available for the diode test.
