PERATING MANUAL

Overview
Warning
To avoid electric shock or personal injury, read the “Safety Information” and “Rules for
Safety Operation” carefully before using the Meter.
Pocked-Sized Digital Multimeter (hereafter referred to as “the Meter”) is a 3 3/4 digits with
steady operations, fashionable structure, low power consumption and highly reliable hand-held
measuring instrument. The Meter uses large scale of integrated circuit with double integrated
A/D converter as its core. The Meter not only can measure AC/DC Voltage, Resistance,
Capacitance, Frequency, Diodes and Continuity, but also has D-HOLD, Full Icon Display, Duty
Cycle and Sleep Mode features.

This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category
(CAT. II 300V) and double insulation.
CAT. II: Local level, appliance, PORTABLE EQUIPMENT etc., with smaller transient voltage
overvoltages than CAT. III
Use the Meter only as specified in this operating manual, otherwise the protection provided by
the Meter may be impaired.
In this manual, a Warning identifies conditions and actions that pose hazards to the user,
or may damage the Meter or the equipment under test.
A Note identifies the information that user should pay attention on.
International electrical symbols used on the Meter and in this Operating Manual are explained
on page 7.

Rules For Safe Operation
Warning
To avoid possible electric shock or personal injury, and to avoid possible damage
to the Meter or to the equipment under test, adhere to the following rules:
Before using the Meter inspect the case. Do not use the Meter if it is damaged or
the case (or part of the case) is removed. Look for cracks or missing plastic.
Pay attention to the insulation around the connectors.
Inspect the test leads for damaged insulation or exposed metal. Check the test
leads for continuity.
Do not apply more than the rated voltage, as marked on the Meter, between the
terminals or between any terminal and grounding.
The rotary switch should be placed in the right position and no any changeover of
range shall be made during measurement is conducted to prevent damage of the
Meter.
When the Meter working at an effective voltage over 60V in DC or 30V rms in AC,
special care should be taken for there is danger of electric shock.
Use the proper terminals, function, and range for your measurements.
Do not use or store the Meter in an environment of high temperature, humidity,

KMD-S04

explosive, inflammable and strong magnetic field. The performance of the Meter
may deteriorate after dampened.
When using the test leads, keep your fingers behind the finger guards.
Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes or capacitance.
Replace the battery as soon as the battery indicator appears. With a low
battery, the Meter might produce false readings that can lead to electric shock
and personal injury.
Remove the connection between the testing leads and the circuit being tested,
and turn the Meter power off before opening the Meter case.
When servicing the Meter, use only the same model number or identical electrical
specifications replacement parts.
The internal circuit of the Meter shall not be altered at will to avoid damage of the
Meter and any accident.
Soft cloth and mild detergent should be used to clean the surface of the Meter
when servicing. No abrasive and solvent should be used to prevent the surface of
the Meter from corrosion, damage and accident.
The Meter is suitable for indoor use.
Turn the Meter power off when it is not in use and take out the battery when not
using for a long time. Constantly check the battery as it may leak when it has

been using for some time, replace the battery as soon as leaking appears. A
leaking battery will damage the Meter.

Operation Performed
SELECT
Presses SELECT to switch between resistance, capacitance, continuity
buzzer and diode measurement modes; the Meter beeps. Resistance
measurement is default.
D-HOLD
Press D-HOLD once to enter hold mode.
Press D-HOLD again to exit hold mode.
In Hold mode, is displayed and the present value is shown.
Hz/DUTY
Press Hz/DUTY at DCV to step through DCV, frequency and duty
cycle measurement mode. AUTO on the LCD will be disappeared.
Press Hz/DUTY at ACV to step through ACV, frequency and duty
cycle measurement mode. AUTO on the LCD will be disappeared.
The Meter will be at DCV: 400mV or ACV: 4V after stepping through

frequency and duty cycle measurement mode. Therefore it is
necessary to turn the rotary switch or turn off and on the Meter to
resume to auto ranging mode when measuring higher voltage.
RANGE
AC/DC voltage and Resistance measuring ranges can be selected manually
or automatically by pushing the range control button. Push this button as
follows to choose range control mode and needed ranges.
