5.1 Akumuliatoriaus įdėjimas

1. Raskite baterijų skyriaus dangtelį jutiklio gale.
2. Open the cover and insert the provided 9V (6F22) battery, ensuring correct polarity.
3. Saugiai uždarykite akumuliatoriaus skyriaus dangtelį.

5.2 Connecting the Output Wire

The sensor comes with an integrated output cable. The core wire provides the signal positive output, and the shielding wire serves as the signal ground. Connect the BNC plug of this cable to a compatible measuring instrument (e.g., digital multimeter, oscilloscope, power quality analyzer).

6. Operacija

6.1 Powering On and Range Selection

1. Locate the POWER switch on the sensor.
2. Slide the switch to select the desired output range: 10mV / A or 100mV / A. The "OFF" position powers down the device.
3. The selected range determines the output voltage per ampere of measured current. For example, 100mV/A means 100mV output for every 1A of current.

6.2 Nulinis kalibravimas

Before taking measurements, especially for DC current or leakage current, it is crucial to perform a zero calibration to eliminate external electric field interference and ensure accuracy.

1. Ensure no current is flowing through the clamp žandikaulis.
2. Locate the ZERO adjustment knob (often a rotary knob) on the sensor.
3. Rotate the knob until the connected measuring instrument displays zero current.

6.3 Matavimai

1. Atidarykite klamp žandikaulį paspausdami gaiduką.
2. Place the wire carrying the current to be measured inside the center of the clamp jaw. Ensure only one conductor is within the jaw for accurate measurement.
3. Atleiskite gaiduką, kad uždarytumėteamp žandikaulis tvirtai apvyniokite laidininką.
4. Read the current value from your connected measuring instrument, applying the selected output ratio (e.g., if 100mV/A is selected and the instrument reads 500mV, the current is 5A).
5. For optimal accuracy, ensure the tested wire is positioned in the jaw's center.
