high-precision
instrument,
designed
by
our
excellent
technology.
Before
you
use
your
new
instrument,please
read
this
Operators
Manual
completely
and
familiarize
yourself
Thoroughly
with
all
functions
and
connections.With
proper
use
and
care
your
Digital
Multimeter
will
give
you
years
of
satisfactory
service.
SAFETY RULES
*Alwavs check to make sure that the function switch is set
to the proper position.
*When making measurements,CAUTION as dangerous
voltages may be present in normally safe areas.
*Always disconnect the circuit under test prior to attaching
test leads,as voltages may be present in capacitors even
when the main power is disconnected.
*To avoid electrical shock,use CAUTION when working
above 60V DC or25V AC rms.Such voltages pose a shock
hazard.
*Make sure all power(AC or DC)is disconnected
(OFF)when making resistance(OHMS)measurements.
*Never make measurements with the battery cover of
battery case OFF.
*Never fail to keep the maximum tolerable input.
*The POCKET PERSONAL DMM is designed for low
voltage applications.The measurement should be limited to
the circuit under 450V(AC/DC)
*Never use this meter if it is WET,DAMP or has
condensation on it or the probes.
*When making measurements MAKE SURE your hands
NEVER touch anything except the plastic part of the
probes.
