When current flows from the upside to the
underside of the instrument, the polarity of the
reading is positive (+). Othewise, the polarity of
the reading is negative (-).
Never use the instrument on a circuit with a
voltage higher than 600 VAC/DC. Otherwise,
electric shock hazard or damage to the
instrument or the circuit under test may result.

Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instrument
61010 establishes safety standards for various electrical
environments, categorized as O to CAT IV, and called
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
CAT II : Primary electrical circuits of equipment connected
to an AC electrical outlet by a power cord.
CAT III : Primary electrical circuits of the equipment
connected directly to the distribution panel, and

4. Preparation for Measurement
4-1 Checking Battery Voltage
Set the function selector switch to any position
. When the display is clear without
showing, proceed to measu-rement.
When the display blanks or
replaces the batteries according to the instructions
described in section 9. Battery Replacement.
The sleep feature automatically turns the instru-
ment off in a certain period of time after the last
switch operation. Therefore, the display may
be blank with the function selector switch set
to a position other than
instrument in this case, set the switch back to
position, then to the desired position,
or press any switch. If the display still blanks, the
batteries are exhausted. Replace the batteries.
4-2 Checking Switch Setting and Operation

to the correct position and the data hold switch
is deactivated. Otherwise, desired measurement
◦ Do not make measurement on a circuit with a
voltage higher than 600 V AC/DC. Otherwise,
shock hazard or damage to the instrument or
equipment under test may result.
◦ 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
