５．Preparation for Measurement
５−1 Checking Battery Voltage
Set the function selector switch to any position other than "OFF".
When the
BATT
display is clear without " " showing, proceed to measurement. When the
display blanks or " BATT " is indicated, replace the batteries according to the
instructions described in section 8. Battery Replacement.
NOTE
(1) Set the function selector switch to the "400V" or "750V" position. "
The sleep feature automatically turns the instrument off in a certain period of
(2) Plug the red test lead into the V terminal and the black test lead into the
time after the last switch operation. Therefore, the display may be blank with the
function selector switch set to a position other than "OFF". To operate the
instrument in this case, set the switch back to the "OFF" position, then to the
(3) Connect the test lead prods to the circuit under test and take the reading
desired position, or press any button. If the display still blanks, the batteries are
exhausted. Replace the batteries.
５−２ Checking Switch Setting and Operation
Make sure that the function selector switch is set to the correct position and
the data hold function is deactivated. Otherwise, desired measurement cannot
be made.

# WARNING
● This instrument is designed to work in distribution systems where the line to
earth has a maximum voltage of 300V. Be sure to use it within this rated
voltage.
● Transformer jaw tips are designed to minimize the possibility of shorting
conductors in the circuit under test. If equipment under test has exposed
conductive parts, however, extra precaution should be taken to avoid possible

Note:
◇If one of the test leads has an open, the display reads "OL".
◇ During current measurement, keep the transformer jaws fully closed.
Otherwise, accurate measurement cannot be made. The maximum
conductor size is 33mm in diameter.
◇ When measuring a larger current, the transformer jaws may buzz. This does
not affect the instrument's accuracy.

read through these operating instructions before using the instrument.
# WARNING
● Read through and understand instructions contained in this manual before
starting using the instrument.
● Save and keep the manual handy to enable quick reference whenever
necessary.
● Be sure to use the instrument only in its intended applications and to follow
measurement procedures described in the manual.
● Be sure to understand and follow all safety instructions contained in the
manual. Failure to follow the above instructions may cause injury, instrument
damage and/or damage to equipment under test.
# symbol indicated on the instrument means that the user must refer to
related parts in the manual for safe operation of the instrument. Be sure to

# DANGER
● This instrument is designed to work in distribution systems where the line to earth
has a maximum voltage of 300V. Be sure to use it within this rated voltage.
● Do not attempt to make measurement in the presence of flammable gasses,
fumes, vapor or dust. Otherwise, the use of the instrument may cause
sparking, which can lead to an explosion.
● Transformer jaw tips are designed not to short the circuit under test.
If equipment under test has exposed conductive parts, however, extra
precaution should be taken to minimize the possibility of shorting.
●Never attempt to use the instrument if its surface or your hand is wet.
●Do not exceed the maximum allowable input of any measurement range.
●Never open the battery compartment cover when making measurement.
● Never try to make measurement if any abnormal conditions, such as broken
