△！ CAUTION : This symbol indicates the contents "Possibilities of the injury or
only the material damage can be supposed" caused from mis-
operations.
△！ WARNING
POSSIBLE ELECTRICAL SHOCK
● When using this instrument in the circuit more than AC 1000V, operate very
carefully (always wear the rubber gloves).
● Apply only the coated cables and do not clamp the bare cables.
● Do not handle the instrument in the rain, at humid place, with a drop of water
and or with wet hands.
● Do not use the instrument if the CT case, instrument body and or rubber handle
cover are damaged. Replace the rubber handle cover to new one, if it is damaged.
● Do not disassemble this instrument
● High voltage circuit is very dangerous and people without expertise should not
operate the instrument.

4. OPERATION
4-1 PREPARATION BEFORE MEASUREMENT
Battery Installment:
① Confirm the power switch OFF.
② The battery cover is fixed by screw and turn it to the left for removing cover.
③ Install the batteries according to the indication of battery case (do not mistake
to place “+” and “－” polarity).
④ After the replacement, put the battery cover to the original position firmly.

● 「B」sign will appear on the display when batteries are exhausted and get less
than operation voltage. Replace to new batteries immediately.
● Do not use the batteries mixed new one and once used and or different kind ones.
△！ WARNING
POSSIBLE ELECTRICAL SHOCK OR ACCIDENT
● Do not replace the batteries under the conditions of measuring current or
voltage
● Do not operate the instrument with battery cover off.
△！ CAUTION
When not using the instrument for a long period, remove the batteries and keep
separately. The batteries may leak and may cause damage to the instrument.
4-2 OPERATION METHOD
① Power switch on and select the appropriate Cable to be
range to be measured by range select switch. measured
② Push up CT guide to the conductor to be measured
for clamping CT.
③ Push Data Hold switch to hold measured value.
④ After measurement, pull out CT from the conductor
and read the measured value.
⑤ Set power switch off after finished operation.
When “B” mark appears on LCD during measurement,
replace the batteries immediately, as the batteries are
consumed and get lower than operation voltage.
△！ CAUTION
POSSIBLE DAMAGE OF INSTRUMENT
● Do not apply the current more than 20A to the instrument, as it may cause
damage and heating by giving excess big current to CT.
● This model is high precision measuring instrument. It may cause defect, if CT
part receives heavy load.
