4. OPERATION

4-1. Connects to DUT
The LCR Meters utilize the structure of four wires measurement which allows
accurate, easy, and stable measurements and avoids mutual inductance and
interference from measurement signals, noise and other factors inherent with
other types of connections. For the accuracy of measurement, GOODWILL
produces the cable set and test fixture (option) for connection directly to the
front panel BNC connectors.
4-2. Start-Up
Connects the power cord of the LCR Meters to the mains socket-outlet. Presses
the POWER button of front panel to apply the AC power to the LCR Meters.
4-3. Zeroing
In order to eliminate strayed capacitance and impedance of test cable during the
measurement, the LCR Meters should be zeroed to correct for test cable and/or
test fixture errors before taking measurements. The corrections are calculated
and stored in memory of the LCR Meters during the zeroing process. Open and
short circuit zeroing should be done for test cable and/or test fixture. For the best
accuracy, the test cable and/or test fixture should be zeroed once per day at least
and each time test cable or test fixture is changed in general.
The zeroing process of open and short circuits are following:
Open Circuit
!
The test cable or test fixture should be open with no component connected.
! Press MENU key.
!
Press F1 key to select "OFFSET" menu.
! Press F1 key to select open circuit zeroing (the "CAP OFFSET" is indicated
on the adjacent LCD monitor.).
