5. Istruzioni per l'uso
5.1 Funzionamento generale
- Accensione/spegnimento: Rotate the dial from the OFF position to any measurement function to turn the meter ON. Rotate back to OFF to power down.
- Gamma automatica: The meter automatically selects the appropriate measurement range for most functions.
- Retroilluminazione/Torcia: Press the dedicated button (often labeled with a light bulb icon) to activate the display backlight or the integrated flashlight. This feature is particularly useful in dimly lit environments.

5.2 Modalità di misurazione
Misurazione della corrente AC/DC (Clamp)
To measure AC or DC current using the clamp mascella:
- Rotate the dial to the AC A or DC A position.
- Aprire il clamp jaw and enclose only uno conductor (wire) through the center of the clamp.
- Read the current value on the display. For DC current, press the REL/ZERO button to zero the reading before measurement if needed.

Figura 5.2: Misurazione della corrente CA/CC
This image shows the clamp meter measuring current by enclosing a single wire, demonstrating its non-contact current measurement capability.
Volume AC/DCtage Misurazione
Per misurare il volume AC o DCtage:
- Rotate the dial to the AC V or DC V position.
- Collegare i puntali di prova ai punti del circuito in cui la tensione ètage deve essere misurato.
- Leggi il vol.tage valore sul display.

Figura 5.3: Vol. AC/DCtage Misurazione
This image illustrates the clamp meter performing a voltage test using its test leads, showing the display with a voltage lettura.
Resistance, Capacitance, Diode, Continuity
Rotate the dial to the Ω (Ohms) or Capacitance symbol. Use the FUNC button to cycle through Resistance, Diode, and Continuity modes. Connect test leads to the component being measured.
Misurazione della temperatura
Rotate the dial to the °C/°F position. Connect the thermocouple to the input jacks. Place the thermocouple tip on the object or area whose temperature is to be measured.
NCV (Volume senza contattotage) Rilevamento
Rotate the dial to the NCV position. Move the top of the clamp misuratore vicino a un conduttore sotto tensione. Il misuratore indicherà la presenza di tensione alternatatage through audible beeps and visual indicators on the display.
Misurazione della corrente di spunto
The Inrush function is used to measure the initial surge of current when an electrical device is turned on. This function is only available in AC current mode.
- Rotate the dial to the AC A position.
- Press the Inrush button.
- Aprire il clamp jaw and enclose the single conductor of the device to be tested.
- Turn on the device. The meter will capture and display the peak inrush current. The measuring time is approximately 100ms. This function works best when the current is greater than 10A.

This image shows the clamp meter performing an inrush current test on an electrical circuit, with the display showing the measured inrush value.
VFD (Variable Frequency Drive) and LoZ (Low Input Impedance) Modes
These advanced modes provide higher accuracy for specific measurement scenarios:
- VFD: Used for accurate voltage and current measurements on variable frequency motor drives.
- LoZ: Low input impedance mode helps to avoid false readings caused by ghost voltages, providing more reliable measurements.
