Operation
Connecting to the Device Under Test (DUT):
The M3 Digital LCR meter uses a 4-terminal configuration to connect to the DUT. This allows the LCR meter
to apply current to the DUT with one pair of terminals (High Drive and Low Drive) and to measure the voltage
across the DUT with the other pair (High Sense and Low Sense). This configuration increases accuracy for
lower impedance measurements. For all measurements, except transformer measurements and special
configurations, the two RED clips (HD/HS terminals) will be connected to one lead of the DUT and the two
BLACK clips (LS/LD terminals) will connect to the other lead.
NOTE: For low impedance measurement, a cable with four independant leads may be used. If possible, twist the
two current leads (HD/LD) and the two voltage leads (HS/LS) separately. The sense signals determine the points
where the impedance is measured.
