Triplett 2030-C Instruction Manual
Model 2030-C
Pocket-Sized DMM
INSTRUCTION MANUAL
TRIPLETT
INTRODUCTION
The Triplett 2030-C Pocket Digital Multimeter uses modern technology to provide the user with a con-
venient, compact, feature packed measuring instrument. The 2030-C measures AC and DC Voltage
and Current, tests Diodes, measures Resistance, Frequency and Capacitance and incorporates a Con-
tinuity Beeper. It features Autoranging or Manual ranging in the voltage and resistance measuring modes,
as well as a battery saving Auto Power Off mode. These abilities make the 2030-C useful in the lab,
shop, car, or home.... by the Electrician, Technician, or Hobbyist.

WARNING!!!
This meter is NOT to be used to measure High Energy circuits (power circuitry fused at
greater than 4KW, such as distribution circuits, power entrance circuits, etc.)
or circuits classified by CE as CATEGORY III (CAT III).
SAFETY RULES AND WARNINGS
• Read all instructions in this manual before using this meter.
• Prior to using the meter in any situation which could result in injury to the user, in order to verify that
the meter is functional and producing a valid reading, test the meter on a circuit(s) known to have
potentials equivalent to the potential that is to be measured. For example, before using the meter to
determine if an AC power line is energized with 120VAC, test the meter on a line known to be
energized with 120VAC.
• Do not exceed the maximum voltage limitations of this meter (see product specifications). Doing so
may damage the meter and/or injure the user.
• When using this meter in schools and workshops, responsible teachers or skilled personnel must
control the usage of this meter.
• Follow the recommendations of any Trade Organizations or Regulatory Agencies whose scope
encompasses the use of this meter.
• Do not use this meter with its battery cover open, its rear case open, or with parts removed.
• Do not open this meter for maintenance without first disconnecting the test leads from all external
circuitry.
• Repairs and maintenance must only be carried out by qualified service personnel or qualified electri-
cians /technicians who know the dangers of, and the safety rules applicable to this type of equipment.
• Use caution when measuring circuits containing capacitors. Capacitors can store dangerous levels of
electricity, even when the circuitry which they are in has been disconnected from its power source.
• Use caution when working with voltages above 25 volts AC or 35 volts DC. Such voltages may cause
a life threatening electrical shock.
• This meter is not for use by children.
• Always set the meter to the appropriate range or mode before connecting it to the circuitry to be
tested.
• Never attempt to make voltage measurements with the Function switch set to DIODE
, OHM
Ω
,
Continuity Beeper
, Frequency (Hz, KHz), or Capacitance
. Doing so may damage the
meter and/or injure the user.
• Do not rotate the Function switch with the test leads connected to the circuitry to be tested. Doing so
may damage the meter and/or injure the user.
• Before using the meter, examine both the meter and the test leads for damage. Do not use the meter
if damage (damaged insulation, exposed metal, cracked case, burnt smell, etc.) is evident.
• Do not use this meter to make measurements in adverse environments such as rain, snow, fog, or
locations with steam, explosive gases or dusts. Doing so may damage the meter and/or injure the user.
• Do not use the meter if either the meter or the test leads are wet, either from exposure to the weather,
or after cleaning the case of the meter. Doing so may cause injury to the user.
• Avoid usage near strong magnetic fields (magnets, loudspeakers, transformers, motors, coils, relays,
contactors, electromagnets, etc.). The meter may display readings that are in error, causing the user
to misinterpret the hazards present. For example, the meter may indicate a low voltage when high
voltages are actually present.
• Avoid usage near strong electrostatic fields (high voltage power lines, televisions, computer monitors,
etc.). The meter may display readings that are in error, causing the user to misinterpret the hazards
present. For example, the meter may indicate a low voltage when high voltages are actually present.
• Avoid usage near strong RF fields (radio or television transmitters, etc.). The meter may display
readings that are in error, causing the user to misinterpret the hazards present. For example, the
meter may indicate a low voltage when high voltages are actually present.
• Do not touch the tips of the test leads when making a measurement. Do not touch live circuitry when
making a measurement.
• Do not apply more than 600 volts DC/AC rms between the test leads and the earth ground. Doing so
may damage the meter and/or injure the user.
• If there is any doubt about the condition of the meter (i.e. safe vs unsafe), remove the meter from
service and secure it in a location that will prevent its unintentional use.
• Do not use the meter if it does not appear to work correctly on all ranges and in all modes.
• Do not use the meter if it has undergone long-term storage under unfavorable conditions.
• Do not use the meter if it may have been damaged in transport.
• Do not attempt immediate use of the meter when bringing if from a cold environment to a warm
environment. Condensation of water, inside and outside of the meter, may produce dangerous
measuring conditions. Allow the meter to warm to room temperature before using.
• Do not use meter in condensing atmospheres. That is, do not use meter in conditions where ambient
temperature and humidity could cause condensation of water inside of meter. Doing so may cause
injury to the user.
• Do not continue to use meter when the “low battery” symbol
+
_
is displayed. The displayed reading
may be in error and lead the user to believe that no hazard exists, when in fact, dangerous voltages
or currents may be present.
• Use caution when attempting to evaluate if a dangerous voltage is present. The meter will not read
AC voltage if it is set to DC, nor will it read DC if it is set to AC. For example, if the meter is set to
200VDC, it will not measure a dangerous AC voltage, even if the probes are inserted into a household
AC wall outlet.
• Do not touch the metallic portion of one test lead if the other test lead is connected to a live circuit.
The current from the live circuit may pass through the meter and appear on the unconnected test
lead. Failure to observe this warning may result in user injury.
• Remove the batteries when the meter may be left unused for longer than 1 month. Chemical leakage
from the batteries could damage the meter, leading to user injury.
• Do not use the meter if there is evidence of chemical leakage from the batteries. Leakage could
damage meter and lead to injury of user.
• Do not modify the meter. Changing the design may make the meter unsafe and may result in injury to
the user.
• Do not attempt to use meter when no display is present on LCD. Doing so may damage the meter
and/or injure the user.
• Use Caution when the meter is in the HOLD mode. In this mode, the meter will not display a new
reading, and consequently, may not indicate the presence of dangerous voltages. i.e. If the meter is
in HOLD and is displaying 1 volt, the meter will continue to display 1 volt, even though 500 volts is
applied to the meter’s test leads.
• When replacing the batteries, dispose of the depleted batteries in accordance with any prevailing
safety or environmental regulations.
