*[Accuracy conditions]

Preheating: at least 15 minutes after power-on.

Temperature: 23±5℃, Humidity: 30%~75%RH, Power supply: AC 100V~ 240V , 45 ~65Hz

Temperature coefficient: When the temperature range is 5~18℃ or 28~40℃, the error increases by ± (displayed value × 0.06 % )/℃.

@ [Ammeter Internal Connection Method]

A voltmeter directly measures the supply voltage, and its two ends are connected across the product under test and the ammeter. This introduces a voltage division measurement error due to the internal resistance of the ammeter.

# [Four-line method]

When measuring at long distances (the distance between the measuring instrument and the product under test is relatively far, usually more than 10 meters), in order to eliminate the voltage drop on the test lines, a four-wire connection method (two voltage lines and two current lines) can be used to directly lead the voltage test lines from both ends of the product under test for test wiring.
