Introduction
Thank you for purchasing the Hioki PW3390 Power Analyzer. To obtain maximum performance from the
product, please read this manual first, and keep it handy for future reference.
To measure current, the power analyzer requires clamp-on current probes or AC/DC current probes
(Options, (p. 3), afterwards referred to generically as “current sensors”). See your current sensor’s
instruction manual for details.

Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and dgt. (digit) values, with
the following meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale length. This is usually the name of the
currently selected range.
rdg. (reading or displayed value)
The value currently being measured and indicated on the measuring instrument.
dgt. (resolution)
The smallest displayable unit on a digital measuring instrument, i.e., the input value
that causes the digital display to show a "1" as the least-significant digit.
Safety Notes
HIOKI PW3390A961-06
Measurement categories
This instrument complies with CAT II (1000 V) and CAT III (600 V) safety requirements.
To ensure safe operation of measurement instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT II to CAT IV, and called measurement categories.
CAT II Primary electrical circuits in equipment connected to an AC electrical outlet by a power
cord (portable tools, household appliances, etc.) CAT II covers directly measuring electrical outlet receptacles.
CAT II covers directly measuring electrical outlet receptacles.
CAT III Primary electrical circuits of heavy equipment (fixed installations) connected directly to the
distribution 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 pri-
mary overcurrent protection device (distribution panel).
Using a measurement instrument in an environment designated with a higher-numbered category than that for
which the instrument is rated could result in a severe accident, and must be carefully avoided.
Use of a measurement instrument that is not CAT-rated in CAT II to CAT IV measurement applications
could result in a severe accident, and must be carefully avoided.

Handling the instrument
HIOKI PW3390A961-06
To avoid electric shock, do not remove the instrument's case. The internal components of the instrument carry high voltages and may become very hot during
operation.
• If the instrument exhibits abnormal operation or display during use, review the information in Troubleshooting section "11.2 Troubleshooting" (p. 223) and Error Indications section "11.3 Error Indication" (p. 226) before contacting your authorized Hioki
distributor or reseller.
• To avoid damage to the instrument, protect it from physical shock when transporting

• To move the instrument, first disconnect a
memory, and carry it by the handle.
• Do not apply heavy downward pressure with the stand extended. The stand could

• Current sensor and voltage cables should only be connected to the secondary

occurs. Connections should never be made to the primary side of a breaker,
because unrestricted current flow could cause a serious accident if a short circuit occurs.

• To avoid electric shock and short-circuit accidents, use only the specified voltage

• For safety reasons, when taking measurement
Avoid stepping on or pinching cables, which could damage the cable insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it

• Keep the cables well away from heat sources, as
if the insulation melts.

Usage Notes
Before connecting to the lines to be measured
To avoid electrical hazards and damage to the instrument, do not apply voltage
exceeding the rated maximum to the external input terminals.
• To avoid electrical accidents, confirm that all connections are secure. The
increased resistance of loose connections can lead to overheating and fire.
• Ensure that the input does not exceed the maximum input voltage or current to
oid instrument damage, short-circuiting and electric shock resulting from
av
heat building.
• When the power is turned off, do not apply voltage or current to the voltage input terminals, current input terminals, or current sensors. Doing so may damage the instrument.
• Note that the instrument may be damaged if the applied voltage or current exceeds
th
e measurement range.
While measuring
If an abnormality such as smoke, strange sound or offensive smell occurs, stop
measuring immediately, disconnect from the measurement lines, turn off the
instrument, unplug the power cord from the outlet, and undo any changes to the
wiring. Contact your authorized Hioki distributor or reseller as soon as possible.
Continuing to use the instrument may result in fire or electric shock.
