Making Measurements
To ensure that the instrument is properly operating, conduct an inspection and check instrument operation before using instrument to ensure
that no damage has occurred during storage or transport. Verify that the tips of the jaws are free of damage and cracking. If there is any
damage to the instrument, contact your authorized Hioki distributor or reseller for repair.
DANGER
•To prevent an electric shock, do not touch any areas beyond the barrier while the instrument is in use.
•The maximum measurement current varies with the frequency, and the current that can be measured
continuously is limited. Operating the instrument at less than this limitation is referred to as derating. Do not
measure currents in excess of the derating curve. Damage to the instrument or overheating can malfunction,
a re, or burn.
Ax around the wire and check the measured value.
AC current measurement, frequency measurement
• Clamp the instrument on one wire only.
• Put the conductor perpendicular to the sensor.
• Correct measurement may be impossible for the case of rush
• At a low temperature, there are cases when the reading may not

• Press RANGE key for 1 sec. or more to switch frequency

• For measurement of grounded wires, clamp the instrument on one
• For overall measurement, clamp the instrument on the entire
• To measure a single-phase 2-wire circuit, clamp both of the circuit’s
wires together.
• To measure a 3-phase 4-wire circuit, clamp all 4 of the circuit’s
wires bundled together. If this is not possible, carry out the
measurement on the equipment’s ground wire.
• Measurement may not be accurate in the cases below.
(2) If you use the instrument to measure the waveforms on the
secondary side of an inverter, or other special waveforms.
• Note that a large display count may appear momently when
opening or closing the jaws. This is not an error. It may take
some time for the display to return to zero. However, starting

The measured value is beyond the measurable
range of current measurement. Halt
measurement as the instrument is in an over-
input state.
The backlight will also turn red if the comparator

Repairs, Inspections, and Cleaning
is not discharged before contacting your authorized Hioki distributor
or reseller.
During shipment of the instrument, handle it carefully so that it is not
damaged due to a vibration or shock.
Cleaning
If the instrument becomes dirty, wipe the instrument clean with a soft
cloth slightly moistened with water or a neutral detergent.
Error display
When an error is displayed on the LCD screen, repair is necessary.
Please contact your authorized Hioki distributor or reseller.

Wireless function (GENNECT Cross)
When the wireless function is enabled, you can review measurement
data and create measurement reports on mobile devices. For more
information about this functionality, see the Help function in the
GENNECT Cross (application software, free of charge).
1
Connect the Z3210 Wireless Adapter (option) to the
instrument.
2. Remove the
battery cover by
turning screws.
3. Remove the
protective cap.

Exercising care to orient
the Z3210 correctly,
insert the Z3210 as far
as it will go.
5. Replace the battery cover and secure in place with the screw.

• The communication distance is approx. 10 m (line of sight). The distance
over which data can be sent and received varies greatly depending on
whether there are any obstructions between the paired instruments (for
example, walls, metal barriers, etc.) and on the distance between the
adequate signal strength.
• Although this application software is provided free of charge, downloading
or using the application software may incur internet connection charges.
Such charges are the sole responsibility of the user.
• This application software is not guaranteed to operate on all mobile devices.
Event function
By using GENNECT Cross, you can set a
threshold value as desired and record data if it is
exceeded. The instrument displays the number
of events recorded. For more information, see
