After ensuring the transducer is powered on correctly, we begin using the transducer to measure current. The Hangzhi transducer can measure both AC and DC current; here, we use DC as an example. When testing DC, the positive direction of the current must be consistent with the direction indicated by the arrow on the top of the transducer. We output a 50A DC current to be measured using a standard source, and you can see the corresponding secondary side output current displayed on the 6½-digit multimeter. Further adjusting the standard source by 10%, you can see that the 6½-digit display value changes significantly in sync with the measured current.

In addition to directly measuring current as described above, to adapt to systems that can only acquire voltage signals, a measuring resistor can be connected in series on the secondary side of the transducer. The current can be calculated by measuring the voltage across the resistor. The resistor value must be strictly configured according to the datasheet. The datasheet indicates that the HIT500 can be configured with resistors from 0-5Ω. Now we will use a 5Ω resistor for testing.

After connecting the resistor, switch the 6½-digit multimeter to voltage mode. We output a 50A measured current using a standard source, and we can see the corresponding secondary side output voltage displayed on the 6½-digit multimeter.

• Tip 6: When wiring, ensure that the measuring resistor is securely connected to the transducer output port.
• Tip 7: Avoid product malfunction due to an open circuit at the output terminal.
