Elenco Electronics M-1000B, Operator'S Instruction Manual

Safety Symbols

This marking adjacent to another marking,  terminal,
or operating device indicates that the operator must
refer to the explanation in the operating instructions
to avoid damage to the equipment and/or to avoid
personal injury.

This WARNING sign denotes a hazard.

It calls

attention to a procedure, practice or the like, which if
not correctly performed or adhered to, could result in
personal injury.

This CAUTION sign denotes a hazard.

It calls

attention to a procedure, practice or the like, which, if
not correctly adhered to, could result in damage to or
destruction of part or all of the instrument.

This marking advises the user that the terminal(s) so
marked must not be connected to a circuit point at
which the voltage, with respect to earth ground,
exceeds (in this case) 500 volts.

This symbol, adjacent to one or more terminals,
identifies them as being associated with ranges that
may in normal use be subjected to particularly
hazardous voltages.
For maximum safety, the instrument and its test leads
should not be handled when these terminals are
energized.

This marking indicates that equipment is protected
completely be the double insulation.

2. Introduction

This meter is a 3 1/2 digit digital multimeter that is rugged,
reliable and convenient to use, while providing all of the
accuracy and features needed for any application.

It

performs DC/AC voltage, DC current, resistance,
transistor, and diode. It is designed for technicians and
students.

Transistor h

FE

Measurement

1. Set the RANGE switch to the h

FE

position.

2. Determine whether the transistor is an NPN or PNP-

type and locate the Emitter, Base and Collector
leads. Insert the leads into the proper holes of the
h

FE

socket on the front panel.

3. The meter will display the approximate h

FE

value at

the condition of base current 10

m

A and VCE 2.8V.
