Introduction
Thank you for purchasing the HIOKI "Model 3008 MULTI
TESTER." To obtain maximum performance from the
instrument, please read this manual first, and keep it handy for
future reference.
Overview
This tester is designed for maintenance of industrial power
lines (Max 600 VAC,DC).It is designed in safety and complete
protection against shorting accident, High-power fuse protects
up to 50 kA. Supply current limiting resistance of 10 Ω restricts
short-circuit current.
NOTE:The term "industrial power line" refers to electrical lines
that supply power to electrical equipment and
industrial machinery in factories, buildings, etc. It
does not include indoor lines in ordinary residences
(lines protected by fuses or circuit breakers.)
Safety Information
DANGER
Mishandling this instrument during use could result in injury
or death, as well as damage to the instrument. Be certain
that you understand the instructions and precautions in the
manual before use. We disclaim any responsibility for
accidents or injuries not resulting directly from instrument
defects.
This Instruction Manual provides information and warnings
essential for operating this equipment in a safe manner and for
maintaining it in safe operating condition. Before using this
equipment, be sure to carefully read the following safety notes.

the equipment or to its correct operation.
Inspection
When the unit is delivered, check and make sure that it has not been
damaged in transit. If the unit is damaged, or fails to operate according
to the specifications, contact your dealer or HIOKI representative.
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
DANGER
Observe the following precautions to avoid electric shock.
Always verify the appropriate setting of the range selector
switch before connecting the test leads. Disconnect the
test leads from the measurement object before switching
the range selector switch.
Before taking a measurement, check the position of the
range switch. Do not measure voltage outside the set
voltage range or voltage at levels in excess of the
measurement limit. Doing so may damage the instrument
or cause an accident resulting in injury or death.
Do not input voltage to the resistance measurement
ranges. Doing so may damage the instrument or cause
an accident resulting in injury or death.
If the end of a test lead short-circuits lines with a voltage
between them, this is very dangerous and can lead to a
serious accident. Exercise great care when measuring
voltage.
WARNING
Before using the unit, inspect it and check the operation
to make sure that the unit was not damaged due to poor
storage or transport conditions. If damage is found,
contact your dealer or HIOKI representative.
To prevent electric shock, do not allow the unit to become
wet and do not use the unit when your hands are wet.
To avoid electric shock when measuring live lines, wear
appropriate protective gear, such as insulated rubber
gloves, boots and a safety helmet.
CAUTION
If the protective functions of the unit are damaged, either
remove the unit from service or post warnings to prevent
others from using the unit inadvertently.
Note that the unit may be damaged if voltage or current in
excess of the measurement range is input.
Do not store or use the unit where it will be exposed to
direct sunlight, high temperatures, high humidity, or
condensation. If exposed to such conditions, the unit may
be damaged, the insulation may deteriorate, and the unit
may no longer satisfy its specifications.
After use, be sure to turn the power switch off.
NOTE
If the meter pointer is not positioned in the 0 scale value, use the zero
adjuster to adjust it correctly.
If the fuse is blown, or the test leads are damaged, any range does
not operate. To check the test leads wiring and fuse blowing, refer to
3. Fuse and Test Leads Continuity Check in Battery and Fuse
Replacement.
If the meter cover becomes electrostatically charged, values may
display incorrectly because of attractive forces on the needle. In this
case, apply anti-static treatment to inhibit electrostatic charge buildup.
The efficacy of such electrostatic treatments dissipates over time, so
the treatment may need to be reapplied periodically.
Measurement Procedure
Pre-Operation Inspection
To avoid the possibility of electric shock or incorrect measurement,
check the following items before using the instrument.
WARNING
Before using the instrument check that the body of the
instrument is not damaged. Also make sure that the
insulation on the test leads is undamaged and that no bare
conductors are improperly exposed.
Using the product in such conditions could cause an electric
shock, so contact your dealer or Hioki representative for
replacements. (Model 9060 TEST LEAD)
For voltage measurement, short the test leads and check that 0 V is
indicated.
For resistance measurement, short the test leads and adjust the
reading to zero using the zero ohm adjuster (0 Ω ADJ knob).
Measure a test item with a known value (battery, AC supply, resistor,
etc.) to check that the instrument is functioning correctly.
Voltage Measurement (AC, DCV)
DANGER
The maximum permissible input is 600 VAC/DC. Do not
measure voltage in excess of these limitations (including the
fuse interrupting rating), as doing so may damage the unit or
cause an accident that might result in injury or death.
1. Set the range selector switch to the ACV or DCV range proper for the
voltage to be measured.
NOTE
: If the voltage value is unclear, initially set the range switch to the
600 V range, and after obtaining a reading in this range, change
to the range proper for the voltage value.
2. Connect the black test lead to the Negative (-) terminal, and the red
one to the Positive (+) terminal.
3. Connect the test leads to the circuit to be measured in parallel, then
read the results on the AC/DC scale. When the DCV is selected, if
connecting the red test lead to the positive side, and the black one to
the negative side, then the pointer deflects normally.
NOTE
: When changing the range, disconnect the test leads from the
object to be measured.

Range 150 V
Scale AC/DC 150

Resistance Measurement (Ω )
DANGER
Do not input voltage to the resistance measurement
functions. Doing so may damage the unit or cause an
accident resulting in injury or death.
WARNING
Turn off the power and discharge the capacitors before
measuring resistance in a circuit.
1. Set the range selector switch to the proper Ω range.
Accurate measurement can be made by selecting a range where the
reading will be about the center of the range.
2. Connect the black test lead to the Negative (-) terminal, and the red
one to the Positive (+) terminal.
3. Short the test leads, and use the zero ohm adjuster (0 ΩADJ knob) to
adjust the pointer to the 0 Ω scale.
NOTE
: If the pointer cannot be adjusted to the 0 Ω scale, replace the
battery.
4. Connect the test leads to the circuit to be measured, and read the
value from the scale.
NOTE
: When changing the range, disconnect the test leads from the
object to be measured.
For resistance measurement, the indication may be unstable if the
ends of the test leads are dirty, and the contact is poor. If the
indication is unstable, increase the contact pressure, or clean the
ends of the test leads by wiping with alcohol or similar solvent.
5. In order to obtain the true value, it is necessary to multiply the reading
shown by the factor for the range in use.
