Condensed Operating Instructions
General Information
The 1730T LCR Meter is an instrument for measuring the passive component primary
parameters of inductance (L), capacitance (C), resistance (R) and impedance (Z). Secondary
parameters measured are dissipation factor (D), quality factor (Q), equivalent series resistance
(ESR), reactance (X), phase angle (θ), mutual inductance (M), turns ratio (N), inverse of turns
ratio (1/N) and resistance (R2). Two of sixteen parameters can be measured simultaneously and
the results formatted as value, deviation from nominal, %deviation from nominal or by bin
number. Connection to device under test is through 4-BNC terminals on the front panel.
Start-Up
The 1730T LCR Meter can be operated from a power source between 90-125V or 190-250V AC
at a power line frequency of 50 or 60Hz. The standard 1730T unit is shipped from QuadTech
with a 1A fuse in place for AC 90-125V operation. (A 0.5A fuse is included for AC 190-250V
operation). The 1730T unit is shipped with the line voltage selector set for 115V. Refer to
paragraph 1.4.3 for instructions on changing the fuse or line voltage selector.
Connect the 1730T LCR Meter AC power cord to the source of proper voltage. Operate the
1730T instrument with its chassis connected to earth ground. The 1730T instrument is shipped
with a three-prong power cord to provide this connection to ground. This power cord should
only be plugged into a receptacle that provides earth ground. Serious injury may result if the
1730T instrument is not connected to earth ground.
To turn the 1730T instrument ON, press the power button on the front panel. To switch the
power OFF press the button again or if measurements are to be made proceed with the Test
Parameter Setup in Table COI-1. The 1730T instrument should warm up for 15 minutes prior to
use.
NOTE
Please read this instruction manual in its entirety before operating this instrument.
These condensed operating instructions are not a substitute for all the information provided in the
remainder of this manual.
NOTE
Refer to paragraphs 2.3 through 2.4 for a full description of programming test parameters and
instruction on how to store the test setup. Test parameters must be set before the 1730T
instrument can be zeroed.
