14 LCR meter
In LCR meter mode, channel 1 measures the voltage
across the component under test, and channel 2 measures
the current through it. To measure the current, channel 2
must be connected across an appropriate external shunt.
The easiest way to use the LCR meter is with the ‘LCR
active head’ (see accessories) that fits onto the front of
PsimetriQ and provides 4 wire Kelvin clip connections to
the component under test. The active head provides a
choice of shunts, selectable from the front panel, and
buffers the signals to minimise the effects of stray
capacitance and inductance.
Measurements can be made without the active head by
simply connecting a series shunt (set the LCR head option
in the SETUP menu to ‘none’). This allows measurements
to be made at the full operating voltage range of
PsimetriQ. The shunt chosen must be appropriate for the
voltage, the current and the frequency of operation.
There are three manual connection options, “shunt”,
“divider Zx low”, “divider Zx high”.
