# WARNING
● Never attempt to make measurement if any abnormal conditions,
such as broken case and exposed metal parts are found on the
instrument or cables.
● Verify proper operation on a known source before starting to use
the instrument or taking action as a result of the indication of the
instrument.

● Measurement categories(Over-voltage categories)
To ens ur e sa fe ope ratio n of measu ri ng instru me nts , IEC 61010
est abl ishes safety standards for var iou s ele ctr ica l env ironments,
categorized as O to C
AT IV, and called measurement categories.
Higher-numbered categories correspond to electrical environments
with greater momentary energy, so a measuring instrument designed
for CAT III environments can endure greater momentary energy than
one designed for CAT II.
O : Circuits which are not directly connected to the mains power
supply.
CAT II : Electrical circuits of equipment connected to an AC ele
ctrical
outlet by a power cord.
CAT III : Primary electrical circuits of the equipment connected directly
to the distrib ution 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).

5. Getting started
(1) Checking battery voltage
Set the Function switch to any position other than the OFF position.
When the indications on the display are clearly legible and the
"
" mark is not on, the battery voltage is OK.
If the display is blank or "
" mark is on, replace the batteries
according to Section 8: Battery Replacement.
# CAUTION
● Whe n th e instrume nt is lef t pow ered on, the A uto -po wer -off
function automatically shut s the power off; the dis play will be
blank even if the Function switch is set to any positions other than
the OFF position in this state.
To power on the instrument, rotate the Function switch or press
any of the buttons. If the display is still blank, the batteries are
exhausted.
Replace the batte
ries with the new ones.
(2) Checking Function switch position
Set the Function switch to the appropriate range according to the
measurement purpose. Confirm that the Data hold function is not
activating.
6. Operating instructions
# DANGER
● Never make measurement on a circuit in the following categories;
CAT IV over 600V
CAT III over 1000V
● Ne ve r ope n the Ba tt er y com pa rtmen t cov er whil e mak in g
measurement.
● To avoid getting electrical shock by touching the equipment under
test or its surro undings, be sur e to wear ins ulat ed protective
gears.
(1) Disconnect the Joint
connector according to
the illustration to the right.
(2) Clamp onto one conductor under the test, and re-connect the Joint
connector. Hold the conductor at the center of the Clamp sensor.
(3) Confirm that the Joint connector on the Clamp sensor is firmly
connected.
Note
● Jointed part of the Clamp sensor may be disconnected if excessive
force is applied to.
● Clamp onto one conductor only; measurements cannot be made
when clamping single-phase (2-wi
re) or three-phase (3-wire) at the
same time.
7. Other functions
7-1 Auto-power-off function
This function is to prevent the battery from being exhausted by the
instrument being unintentionally left on.
The instrument automatically shifts to the power-off state about 15
min after the last Function switch or other switch operation.
To exit from the Auto-power-off status, press any button or set the
Function switch to the OFF pos
ition once, and then set it to the
desired range.

8. Battery Replacement
# DANGER
● Do not try to replace the batteries if the surface of the instrument
is wet.
● Ensure that the Clamp sensor is disconnect ed from the object
under test, and that the instrument is powered off when opening
the Battery compartment cover for battery replacement.
● Ne ve r ope n the Ba tt er y com pa rtmen t cov er whil e mak in g
measurement.
# CAUTION
● Do not mix new and old batteries or mix different types of batteries.
● Install batteries in correct polarity as marked inside.
Replace batteries with the new ones when the empty battery mark
is displayed on the LCD. The LCD does not show anything,
eve n the empty ba tte ry mark, when the batte rie s are comp let ely
exhausted.
[ How to replace batteries ]
(1) Power off the instrument.
(2) Loose n the scre w at the ba cks id e
