1J6440B frequency range: 20Hz~3MHz
● 0.02% basic accuracy
● Can apply an external DC bias voltage of DC 0 to ± 60V
Four wire testing can accurately measure extremely low Rs, L, Rdc, and high Q values
Provide two modes of ALC constant voltage and constant current, which can test the test object with highly sensitive response to voltage and current
After calibration, the program is automatically stored and does not require further calibration unless the fixture is changed
● Large LCD screen display, easy to read and view program values
● Provide curve drawing function (only for WK6440B)
