Warning Dangerous

When you notice any of the unusual conditions listed below, immediately
terminate operation and disconnect the power cable.

Please contact the TELEDYNE service center representative for repair of the
instrument. If you continue to operate without repairing the instrument, there
is a potential fire or shock hazard for operators.

The instrument is operating abnormally if:

The instrument emits abnormal noise, smell, smoke, or a spark-like light

during the operation.

The instrument generates high temperature or electrical shock during

operation.

The power cable, plug, or receptacle on the instrument is damaged.

Foreign substances or liquid has fallen into the instrument.

The following general safety precautions must be observed during all phases
of operation, service, and repair of this instrument. Failure to comply with
these precautions or with specific WARNINGS elsewhere in this manual may
impair the protection provided by the equipment. In addition it violates safety
standards of design, manufacture, and intended use of the instrument.

TELEDYNE assumes no liability for the
customer's failure to comply with these
requirements.

To avoid electric shock hazards, the instrument
chassis and cabinet must be connected to a safety
earth ground by the supplied power cable with
earth blade.

Do not operate the instrument in the presence of
inflammable gasses or fumes. Operation of any
electrical instrument in such an environment
constitutes a definite safety hazard.

Safety Summary

Operating personnel must not remove instrument
covers. Component replacement and internal
adjustments must be made by qualified
maintenance personnel. Do not replace
components with the power cable connected.
Under certain conditions, dangerous voltages may
exist even with the power cable is removed. To
avoid injuries, always disconnect the power and
discharge the circuits before touching them.

Do not attempt internal service or adjustment
unless another person, capable of rendering first
aid and resuscitation, is present.

Because of the danger of introducing additional
hazards, do not install substitute parts or perform
unauthorized modifications to the instrument.
Return the instrument to a TELEDYNE
authorized service center for service and repair to
ensure that safety features are maintained.

Introduction

Main Specifications

Feature overview

Thank you for purchasing an T3LCR Series LCR meter.

The TELEDYNE T3LCR Series is a general-purpose
LCR meter for incoming inspection of components,
quality control, and laboratory use.

The T3LCR Series is used for evaluating LCR

signal levels (10.00mV to 2.00V & 100.0uA to 20.00mA).

-in comparator, the T3LCR Series can
output comparison/decision results for sorting
components into a maximum of ten bins. Furthermore,
by using the handler interface, the T3LCR Series can be
easily combined with a component handler, and a system
controller to fully automate component testing, sorting,
and quality-control data processing.

The list measure function permits entry of up to 10
frequencies or test signal levels points to be automatically
measured.

You can specify the primary parameter limit values in
one of the following 3 ways:

Tolerance mode [%][ ]

In tolerance mode, the comparison limit values are
based on the deviations from the specified nominal
value, which can be specified in the [NOM] field.
You configure the tolerance mode limit values as a
deviation percentage (%) or absolute ( ) parameter
value.

Sequential mode [SEQ]

In sequential mode, the comparison limit values are
based on the absolute value of the measurement.
When you configure these limit values, you have to
first define the minimum value and then the
maximum value.

Nominal Value [NOM]

Sets the nominal value (reference value) for the

The device uses the RS-232 interface or USB interface to communicate with
the computer to complete all functions. With standard SCPI
commands, users can easily create various acquisition system which are
suitable for themselves.

You can connect a controller (i.e. PC and PLC) to the
RS-232 interface using a TELEDYNE RS-232 DB-9
cable. The serial port uses the transmit (TXD), receive
(RXD) and signal ground (GND) lines of the RS-232
standard. It does not use the hardware handshaking lines
CTS and RTS.

The following conventions and definitions are used in this chapter to describe
RS-232 operation.

< > Angular brackets enclose words or characters that are used to symbolize a
program code parameter or an RS-232 command.

[ ] A square bracket indicates that the enclosed items are optional.

\n Command Terminator

The T3LCR commands are divided into two types: Common commands and
SCPI commands.

The common commands are defined in IEEE std. 488.2-1987, and these
commands are common for all devices. The SCPI commands are used to
control all of the T3LCR's functions.

The SCPI commands are tree structured, three levels deep. The highest level
commands are called the subsystem commands in this manual. So the lower
level commands are legal only when the subsystem commands have been
selected.

A colon (:) is used to separate the higher level commands and the lower level
commands.

Semicolon (;) A semicolon does not change the current path but separates two
commands in the same message.

(b) If the 4th character is not a vowel, the short form

Every command and character parameter has at least

two forms, a short form and a long form. In some
cases they will be the same. The short form is
obtained using the following rules.
A) If the long form has four characters or less, the
long form and short form are the same.
B) If the long form has more than 4 characters:
(a) If the 4th character is a vowel, the short form is
the first 3 characters of the long form.
For example:
comparator abbreviated to comp
current abbreviated to curr
range abbreviated to rang

is the first 4 characters.
For example:
resistance abbreviated to res
volume abbreviated to vol

If the long form mnemonic is defined as a phrase

rather than a single word, then the long form
mnemonic is the first character of the first word(s)
followed by the entire last word. The above rules,
when the long form mnemonic is a single word, are
then applied to the resulting long form mnemonic to
obtain the short form.
For example:
PercentTolerance abbreviated to ptol

The commands consist of a command header and parameters. (See the

Example:

Header Parameter

Headers can be of the long form or the short form. The

long form allows easier understanding of the program
code and the short form allows more efficient use of the
computer.

Parameters may be of two types as follows.
(A) Character Data and String Data Character data
consists of ASCII characters. The abbreviation rules are
the same as the rules for command headers.
(B) Numeric Data
(a) NR1 integer: For example, 1,+123,-123
(b) NR2 fix float: For example, 1.23,+1.23,-1.23
(c) NR3 floating point: For example, 1.23e3,

The available range for numeric data is 9.9E37. When
numeric data is used as a parameter, the suffix multiplier

be used with the suffix unit.) can be used for some
