DUAL DISPLAY L/C/R METER
MZ-505C
1 GENERAL
1.1 Introduction
This 19.999 count L/C/R hand-held meter is a special
microprocessor-controlled meter for measuring functions of
inductance, capacitance and resistance. Simple to operate, the
instrument not only takes absolute parallel mode measurements, but
also capable of series mode measurement. The meter provides
direct and accurate measurements of inductors, capacitors and
resistors with different testing frequencies. It is selectable for auto
and manual ranging.
Front panel pushbuttons maximize the convenience of function
and feature selection such as data hold; maximum, minimum and
average record mode; relative mode; tolerance sorting mode;
frequency and L/C/R selection.
The test data can be transferred to PC through an full isolated
optical RS232C interface.
A tilt stand provides position flexibility for viewing and operating
the meter. The over-melding plastic and rubber case protects the
meter to be stronger. With single 9V battery operation is standard for
the meter, a DC 12V power adaptor can also be used as an optional
power input.

specified ones to ensure safety:
Battery 9V 6F22.
* Observer all specified ratings both of supply and
measurement.
* Use this instrument under the specified environmental
conditions.
* Remember that voltages higher than 70 V DC or 33 V AC rms
are dangerous.
* The user is only authorised to carry out the following
maintenance operations:
Replace the battery.
Fuse replacement
On the Maintenance paragraph the proper instructions are given.
