1. This section is very important for safety. Read and understand the
following instruction fully and maintain your instrument properly.
2. The instrument must be calibrated and inspected at least once a year to
maintain the safety and accuracy.
6-1 Maintenance and inspection
1) Appearance
• Is the appearance not damaged by falling?
2) Test leads
• Is the cord of the test leads not damaged or the core wire not exposed at
any place of the test leads?
If any of the above is found with the appearance, do not use the equipment
and have it repaired.
6-2 Calibration
The manufacturer may conduct the calibration and inspection. For more
information, please contact the dealers.

1. The main unit is not resistant to volatile solvent and must not be cleaned
with lacquer thinner or alcohol. If it gets dirty, wipe lightly with a soft cloth
moistened with a small amount of water.
2. The main unit is not resistant to heat. Do not place it near a source of high heat.
3. Do not store the instrument in a place where it may be subjected to
excessive vibrations or from where it may fall.
4. For storing the instrument, avoid hot, cold or humid places or placed
under direct sunlight or where condensation is anticipated.
5. When the instrument is not to be used for a long period, be sure to
remove batteries from it.
6-4 Battery replacement
1. If the rear case or the battery lid is removed with input applied to the input
terminals, you may get electrical shock. Before starting the work, always
make sure that no input is applied.
2. Before starting the work, be sure to turn OFF the main unit power and
release the test leads from the circuit.
5-5 EF (Electric Field) sensing
1 This function identifies the presence of voltage in a simplified manner by
sensing the electric field generated by AC voltage.
Sensing voltage reference: A voltage or electric field of about 60 V or more
can be sensed.
2 When the function switch is set to EF, “EF” is displayed.
3 Antenna
• Noncontact type : An antenna is provided near the ▲ marking on the top
left of the main unit.
• Contact type: Bring the test pin of a test lead (either red or black) in contact
with the target.
More accurate sensing is possible by distinguishing the non-grounded and
grounded sides. “-” is displayed and the buzzer beep is generated on the
non-grounded (hot) side, while “EF” remains displayed and the buzzer beep
is not generated on the grounded side.
* “EF” may sometimes become “-” even on the grounded side. This happens
when the wiring is long, etc.

1. Before EF sensing, check the operation of this instrument using a known
power source.
2. Always keep your fingers behind the finger guards on the probe when
making EF sensing.
3. Note that the voltage is not always absent and that a voltage below the
sensing voltage may exist.
Check the following items before starting the daily measurement work.
• Appearance check : Check the appearance of the meter to see if it is free
from damage caused by falling, etc.
• Accessory : Check that the test leads are free from irregularities such as
wire disconnection and crack.
• Battery: Install the battery before using the meter for the first time. Ensure
low battery indication is not displayed and, if it is displayed,
that the
replace the battery with new one. If nothing is displayed, the battery may be
exhausted totally (see 6-4).
• Test lead wire disconnection can be checked by setting the function switch
to and shorting the test pins.
• Also check that the meter and your hands are not moistened by water, etc.

2-1 Applications
Before use, read the following safety precautions.
The following instructions are intended to prevent personal injury such as
burn and electric shock. Be sure to follow them when using the tester.
1. This instrument is a digital multimeter for metering low voltages. Never
use it on electric circuits that exceed CAT.IV 1000 V.
2. Pay special attention when measuring the voltage of AC 33 Vrms (46.7 V
peak) or DC 70 V or more to avoid injury.
3. Never apply an input signal exceeding the maximum rating input value (see 1-3).
4. Never use the meter for measuring the line connected with equipment (i.e.
motors) that generates induced or surge voltage since it may exceed the
maximum allowable voltage.
5. Never use meter if the meter or test leads are damaged or broken.
6. Never use uncased meter or the meter without the lid.
7. Always keep your fingers behind the finger guards on the probe when
making measurements.
8. Be sure to disconnect the test pins from the circuit when changing the function.
9. Before starting measurement, make sure that the function and range are
properly set in accordance with the measurement.
10.Never use meter with wet hands or in a damp environment.
11.Never open tester case except when replacing batteries.
Do not attempt any alteration of original specifications.
12.To ensure safety and maintain accuracy, check the meter in the start-up
inspection as well as in the inspection/calibration to be performed at least
once a year.
13.The meter is for indoor use only.
14.Wear insulating protective gear when using the meter with equipment
containing a hazardous live part. Also be sure to observe your local and
national safety rules.
15. Always use the meter in a specified method to prevent the protective
function from being imperiled.
