1. GENERAL
1.1. INTRODUCTION
The PM 6303 RCL meter is used for measurements of resistances, capacitances and inductances. Pro-
viding auto-function and auto-ranging facility the instrument allows fast and high precision measure-
ments of passive components over awide range.
The component under test is directly connected to the instrument, either via a two-terminal test fix-
ture, afour-wire test cable or afour-terminal test adapter. The measurement result, namely numerical
value, dimension and the equivalent-circuit symbol, is immediately displayed on alarge 4-digit liquid-
crystal display (LCDi, updated at arate of two measurements per second.
Amicroprocessor controls the measurement process, computates the measurement value and transfers
the result to the display.
In the RCL AUTO mode the dominant component, either R, Cor Lof the component under test
is automatically selected for display. RCL AUTO is also the default mode of the instrument after power-
on.
For an inductance e.g. with quality factor 500 >Q>1the instruments indicates the measurement
value of the series inductance and as equivalent-circuit symbol the series connection of aresistance
and an inductance.
In addition to the RCL AUTO mode with display of the dominating component 8further parameters
can be selected by 2pushbuttons providing astepping function, whereby the appropriate parameter
is marked by aLED:
Quality factor Q, dissipation factor D,
parallel resistance Rp^ series resistance Rs,
impedance Z, ...
!parallel capacitance Cp or parallel inductance Lp,
series capacitance Cs or series inductance Ls,
series capacitance, internally biased Cs (2 VBIAS)*
The instrument is especially suited for use in iaboratories, for quality control, service workshops and
for education purposes.-? -

This apparatus has been designed and tested in accordance with Safety Class Irequirements of 1EC
Publication 348, Safety Requirements for Electronic Measuring Apparatus, and has been supplied in
asafe condition* This manual contains some information and warnings which must be followed by the
user to ensure safe operation and to retain the apparatus in asafe condition.
1.2.2. Performance characteristics, specifications
Properties expressed in numerical values with stated tolerance are guaranteed by the manufacturer.
Specified non-toierance numerical values indicate those that could be nominally expected from the
mean of arange of identical instruments.
This specification is valid after the instrument has warmed up for 5minutes (reference temperature
