Tested product：
Warm-up: more than 15min after starting
Temp.: 23±5℃; Humidity: 30%~75%RH; Power supply: AC 100V~240V, 45~65Hz
Temp. coefficient: 5~18℃ or 28~40℃, error plus ± (display ×0.06%)/℃
@ (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.
