cause serious or fatal injury.
# CAUTION is reserved for conditions and actions that can
cause injury or instrument damage.
# DANGER
• Never make measurement on a circuit in which the
electrical potential exceeds AC500V since this instrument
is designed for low voltage measurement.
• Do not make voltage measurements on industry power
lines of 250V or higher.
• Do not attempt to make measurement in the presence of
flammable gasses.
Otherwise, the use of the instrument may cause sparking,
which can lead to an explosion.
• Caution should be taken not to short-circuit the power line
with the test leads when measuring voltages. It may cause
personal injury.
• Never attempt to use the instrument if its surface or your
hand are wet.
Do not exceed the maximum allowable input of any
measuring range.
# WARNING
• Never attempt to make any measurement if any abnormal
conditions, such as a broken cover and test leads or
exposed metal parts are present on the instrument.
• Do not install substitute parts or make any modification to
the instrument.
Return the instrument to your local KYORITSU distributor
for repair or re-calibration in case of suspected faulty
operation.
• Do not try to replace the batteries if the surface of the
instrument is wet.
• Ensure that the test leads are firmly inserted into the terminal.
• Do not make measurement with the instrument case opened.
• Ensure that the test leads are removed from the
instrument, and that the instrument is switched off when
opening the Battery cover for battery replacement.
# CAUTION
• Always set the Function switch to the appropriate position
before making measurement.
• Never rotate the Function switch with the test leads
connected to the equipment under test.
• Set the Function switch to the “OFF” position after use
and remove the test leads. Remove the batteries if the
instrument is to be stored and will not be in use for a long
period.
• Do not give drop impacts and expose the instrument to
direct sunlight, high temperatures, humidity or dew.

6. CAUTION FOR USE
• Make sure to check the fuse. With the range switch set to
one of the ohm ranges short the tips of the test leads. When
the pointer de
flects to the right (zero mark on the ohm scale)
the fuse is OK. If the pointer does not de flect at all replace
the fuse with a new one (0.5A/250V) as it has blown.
• When the pointer is positioned off the zero mark on the
extreme left of the scale turn the zero adjust screw so that
it is set to the zero position. The instrument will not give
accurate readings when used without this zero adjustment.
• Before taking measurements make certain that the
range switch has been properly set. Also, make sure to
remove the test lead tips from the circuit, under test when
switching over the range during measurement.
When the voltage is accidentally applied to the current or ohm
ranges the fuse may blow or the instrument may get damaged.
7. HOW TO MAKE MEASUREMENTS
7-1 DC Voltage Measurements
⑴ Plug the red test lead into the plus terminal and the black test
lead into the minus terminal.
⑵ Set the range switch to DC 500V.
⑶ Connect the red test lead to the plus side of the circuit under
test and the black test lead to the minus side.
⑷ When the reading is below 250V set the range switch to
DC 250V and make the measurement. Follow the same
measurement procedures with the range switch set to the
desired position.
7-2 AC Voltage Measurements
⑴ Plug the red test lead into the plus terminal and the black test
lead into the minus terminal.
⑵ Set the range switch to AC 500V.
⑶ Connect the test lead to the circuit under test.
⑷ As in DC voltage measurements set the range switch to the
desired position and make the measurement.
7-3 DC Current Measurements
⑴ Plug the red test lead into the plus terminal and the black test
lead into the minus terminal.
⑵ Set the range switch to 250mA DC.
⑶ Connect the red test lead to the plus side of the circuit under
test and the black test lead to the minus side.
⑷ When the measurement is possible on lower ranges set the
range switch to the desired position and make the measurement.
7-4 Resistance Measurements
⑴ Plug the red test lead into the plus terminal and the black test
lead into the minus terminal.
⑵ Set the range switch to Ω.
⑶ Short the test lead tips. When the pointer is not positioned
over the zero mark on the ohm scale turn the ohm zero
adjust knob so that it is set to the zero position. When the
pointer does not still read zero replace the battery with a new
one as it is weak.
⑷ Connect the test leads to both ends of the circuit under test.
⑸ Set the range switch to the desired position and make the
measurement.
Note: Make sure to turn off power when the resistance of a
circuit is measured.
7-5 1.5V Battery Test
⑴ Plug the red test lead into the plus terminal and the black test
lead into the minus terminal.
⑵ Set the range switch to 1.5V BATTERY TEST.
⑶ Connect the red test lead to the plus side of the battery and
the black test lead to the minus side for battery tests.
Note: 20Ω load resistor is used for 1.5V battery test.
7-6 Temperature Measurements
⑴ Insert red voltage test lead into plus (+) terminal and black
voltage test lead into minus (−) terminal.
⑵ Set range switch to TEMP position.
⑶ Short the tips of test leads and turn ohm zero adjust knob so
that pointer is positioned on CAL mark of temperature scale
(Fig. 3). After completing this procedure, remove test leads.
⑷ Insert red test lead of temperature probe Model 7060 into
plus (+) terminal and black test lead into minus (−) terminal
(Fig. 4). Read temperature direct from temperature scale.
Note: Refrain from measuring the temperature of metal parts
having a voltage higher than 50V as it is dangerous.
8. FUSE & BATTERY REPLACEMENTS
• Where the fuse has blown remove the housing case and
replace it with a new one.
Make sure to use the 0.5A /250V fuse as speci fied. The use of
any other substitute may damage the instrument.
• When the battery is weak the ohm zero adjustment
becomes impossible. Accurate resistance and temperature
measurements cannot be made without the ohm zero
adjustment. Remove the bottom case for replacement of the
weak battery with a new one.
9．CLEANING METER COVER
Do not try to remove dirt on the meter cover by rubbing hard
with a dry cloth. This can remove anti-electrostatic agent applied
to the surface of the surface of the meter cover.
When the meter reading is affected by electrostatic build up on
the meter cover.
Wipe the meter cover surface using a cloth dampened with off-
the shelf anti-static agent or detergent.
To avid possible deforming or discoloring, do not use solvents.
To clean the body of the instrument, use cloth dampened with
detergent.
# CAUTION
Never use paint thinner, benzene or other solutions
containing solvents for cleaning the instrument.
Otherwise, deforming or discoloring of the instrument body
or the meter cover may result.
Note:
Handle the instrument with care and follow the instructions in
order to maintain it in good condition for a long period of time.
