Data Sheet

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 3½ 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, diode, and audible continuity measurement. It
is designed for technicians and students.
Transistor hFE Measurement
1. Set the RANGE switch to the hFE 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 10μA and VCE 2.8V.
Audible Continuity Test
1. Plug the red test lead into the “V Ω mA” jack and the
black test lead into the “COM” jack.
2. Set the RANGE switch to the position.
3. Connect the test leads to two points of the circuit to be
tested. If the resistance is lower than 100Ω, the buzzer
will sound.
WARNING
CAUTION
500V max.
