1.1 Unpacking and Inspection
Inspect the shipping carton before opening. If damaged, contact the carrier agent immediately.
Inspect the 1730T LCR Meter instrument for any damage. If the instrument appears damaged or
fails to meet specifications notify QuadTech (refer to instruction manual front cover) or its local
representative. Retain the original shipping carton and packing material for future use such as
returning the instrument for recalibration or service.
1.2 Product Overview
The 1730T LCR Meter instrument is a compact yet powerful LCR meter for production or
laboratory testing of inductors, capacitors, resistors and other passive components. The 1730
instrument measures 16 parameters: Ls, Lp, Cs, Cp, Rs, Rp, D, Q, ESR, ⏐Z⏐, Xs, θ, N, 1/N, M,
and R2 and displays two simultaneously. Basic accuracy is ±0.1% for LCR and ±0.001 for DQ
measurements. Ranging is automatic or user selectable. Measurement rate is also selectable
(Slow, Medium or Fast) with rates up to 62 measurements per second. Measurements can be
made continuously or triggered with a programmable delay time up to 10 seconds. The IEEE-
488 and Handler interfaces are standard equipment on the 1730T instrument. External bias
voltage measurements are made via connection to the rear panel terminal strip and levels of 0-5V
DC are possible. Internal bias voltage from 0-5V is attainable using an R
BIAS
resistor across the
rear panel terminal strip. Voltage across and current through the DUT can be monitored using the
test signal. Zero the effects of stray admittance/residual impedance in the test leads with the
open/short correction function. The source impedance of the 1730T instrument is selectable as
100Ω, 100/25Ω, 25Ω, or 10Ω constant current. Ten test frequencies are selectable from 50Hz to
100kHz. The 1730T instrument is equipped with 8 Pass/Fail bins and 50 Store/Recall memory
locations. Test results can be formatted as nominal value, deviation from nominal value or
%deviation from nominal value. Bin number or Pass/Fail can be displayed as well. Connection
to the device under test is through 4 BNC terminals on the front panel.
