5. Asennus

5.1 Akun asennus

1. Paikanna paristolokeron kansi anturin takaa.
2. Open the cover and insert the provided 9V (6F22) battery, ensuring correct polarity.
3. Sulje paristolokeron kansi kunnolla.

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. Käyttö

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: 10 mV / A or 100 mV / 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 Nollakalibrointi

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 leuka.
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 Mittausten tekeminen

1. Avaa clamp leuka painamalla liipaisinta.
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. Sulje luukku vapauttamalla liipaisin.amp leuka tukevasti johtimen ympärille.
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.

8. Huolto

• Puhdistus: Use a soft, dry cloth to clean the sensor. Do not use abrasive cleaners or solvents.
• Varastointi: When not in use for extended periods, remove the battery to prevent leakage. Store the device in a dry environment, away from direct sunlight and extreme temperatures.
• Akun vaihto: Replace the 9V battery when the power indicator light dims or the device fails to power on.
• Kalibrointi: Regular calibration by a qualified technician is recommended to maintain measurement accuracy, especially after prolonged use or if accuracy is suspected to have drifted.
