The LCR-800 has a number of different
measurement modes. Primary and secondary
measurements are displayed on the screen
simultaneously. For detailed information
regarding the measurement combinations, see the
specifications on page 136. The measurement
combinations are shown in the table below.

Series or Parallel equivalent circuits can be
selected. Not all measurement modes can be used
with both series and parallel equivalent circuits.

Set Bias voltage
Background
Voltage bias can be set internally or externally. An
internal voltage bias of 2 volts is normally applied
to a DUT. External voltage bias is able to accept 0
to 30 volts with a maximum current of 200mA. For
external bias voltage connections see page 22.
When measuring a DUT, please allow 1 second to
stabilize a DUT after a bias voltage is applied. In
general a bias voltage should only be applied to
capacitors. If a bias voltage is applied to devices
with low impedance, inaccurate measurements
will occur.
