To measure AC and DC currents using the Sonel C-5A Current clamp, follow these steps:

1. Turn on the clamp by moving the switch to the ON position. The green LED indicates correct operation. If using the battery-powered option, the probe will turn off automatically after 10 minutes of non-use. If using an external power supply, connect the probe to the power supply via the USB port.

2. Before measuring, make sure the gap formed by the faces of the core is clean.

3. Clasp the clamp around the conductor with the current you want to measure. Pay attention to the direction of the arrow on the clamp's jaw to ensure correct measurement of power and DC components. The arrow indicates the direction of current flow.

4. If the measured current exceeds the measuring range of the clamp, the OL (Overload) LED will light up.

5. The output voltage is proportional to the measured current and is conducted by a cable (2.2 m) ended with a pin adapted to the socket on the meter.

6. To measure DC current accurately, perform a DC zero indication correction. After making sure that the jaws are closed and no conductor is between them, connect the clamp to the meter and press the DC ZERO button. The OL LED will be on for about 3 seconds to indicate that the correction is in progress. The OL LED will turn off if the correction is successful. The correction is saved after switching off the clamp.

Note: The Sonel C-5A Current clamp has a measuring range of up to 1400 A for DC and up to 1000 A for AC. The accuracy and additional errors are specified in the technical data section of the manual.
