Introduction
Safety
DANGER
This instrument is designed to comply with IEC 61010
Safety Standards, and has been thoroughly tested for safety
prior to shipment. However, mishandling 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.
The

Inspection
Precautions
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 current measurement,
resistance measurement, and battery test ranges. Doing
so may damage the instrument or cause an accident
resulting in injury or death.
NOTE
: The built-in fuse prevents a short-circuit in a power
line resulting from a malfunction or misuse of the
instrument. However, this built-in fuse protection is
effective for up to 250 VAC commercial power
input.
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
To prevent electric shock, do not allow the instrument to
become wet and do not use the instrument when your
hands are wet.
CAUTION
If the protective functions of the instrument are damaged,
either remove the instrument from service or post warnings
to prevent others from using the instrument inadvertently.
Note that the instrument may be damaged if voltage or
current in excess of the measurement range is input.
Do not store or use the instrument where it will be exposed
to direct sunlight, high temperatures, high humidity, or
condensation. If exposed to such conditions, the instrument
may be damaged, the insulation may deteriorate, and the
instrument may no longer satisfy its specifications.
After use, always turn OFF the power.
Measurement Procedure
Pre-Operation Inspection
WARNING
Use only the supplied Model L9207-30 TEST LEAD.
Before using the instrument, make sure that the insulation
on the test leads is undamaged and that the white or red
portion (insulation layer) inside the cable is not exposed.
Using the instrument in such conditions could cause an
electric shock, so contact your dealer or Hioki
representative for replacements.
(Model L9207-30 TEST LEAD)
Voltage Measurement (AC, DCV)
DANGER
The maximum input voltage is 600 V DC/AC. Attempting to
measure voltage in excess of the maximum input could
destroy the instrument and result in personal injury or death.
CAUTION
Removable sleeves are attached to the metal pins at the
ends of the test leads.
To prevent a short circuit accident, be sure to use the test
leads with the sleeves attached when performing
measurements in the CAT III measurement category.
Remove the sleeves from the test leads when performing
measurements in the CAT II measurement category.
For details on measurement categories, see
“
Measurement
categories
”
in the instruction manual.
When performing measurements with the sleeves attached,
be careful to avoid damaging the sleeves. If the sleeves are
inadvertently removed during measurement, be especially
careful in handling the test leads to avoid electric shock.

DANGER
Do not apply a voltage while a current range is selected.
Applying a voltage may result in damage to the instrument,
or a serious accident.
WARNING
To avoid electrical shock, do not use the instrument to
measure current in circuits of 250 V or greater. The
current function overload protection trips at 250 Vrms.
To prevent electrical accidents, turn the power off before
connecting the test leads and then take measurements.

Measurement categories
This instrument complies with CAT III safety requirements.
To ensure safe operation of measurement instruments, IEC
61010 establishes safety standards for various electrical
environments, categorized as CAT III to CAT IV, and called
measurement categories..
CAT II: Primary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable tools,
household appliances, etc.
CAT II covers directly measuring electrical outlet
receptacles.
CAT III: Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to
outlets.
CAT IV: The circuit from the service drop to the service
entrance, and to the power meter and primary
overcurrent protection device (distribution panel).
Using a measurement instrument in an environment designated
with a higher-numbered category than that for which the
instrument is rated could result in a severe accident, and must
be carefully avoided.
Use of a measurement instrument that is not CAT-rated in CAT
II to CAT IV measurement applications could result in a severe
accident, and must be carefully avoided.
This manual contains information and warnings essential for safe
operation of the instrument and for maintaining it in safe operating
condition. Before using it, be sure to carefully read the following safety
precautions.
Safety symbols
The following symbols in this manual indicate the relative importance of
cautions and warnings.
When you receive the instrument, inspect it carefully to ensure that no
damage occurred during shipping. If damage is evident, or if it fails to
operate according to the specifications, contact your dealer or Hioki
representative.
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.
To avoid the possibility of electric shock or incorrect measurement,
check the following items before using the instrument.
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.
1. Set the range 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 - terminal, and the red one to the +
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.
1. Set the range switch to the DCmA or 60
μ
A range.
NOTE
: If the current value is unclear, initially set the range switch to the
300 mA DC range, and after obtaining a reading in this range,
change to the range proper for the current value.
2. Connect the black test lead to the - terminal, and the red one to the +
terminal.
3. Connect the instrument to the electrical line to be measured in series
(to the cut off line). Connect it so that current flows from the red test
lead to the black one. (If connecting it reversely, the pointer deflects
in the reverse direction.)
NOTE
: When changing the range, disconnect the test leads from the
object to be measured.
4. Read the result on the AC/DC scale.
