@ (Ammeter internal connection]
The voltmeter directly measures the supply voltage, connected with the measured product and the ammeter, with ammeter resistance divider measurement error.
# [Four-wire method]
For long-distance measurement (the measuring instrument is far away from the product under test, usually more than 10 meters), in order to eliminate the voltage drop on the test line, a four-wire connection method (two voltage lines, two current lines) with voltage lines directly connected with both ends of the product can be adopted.
