Measurement categories (Overvoltage categories)
This instrument complies with CAT I safety requirements.
To ensure safe operation of measurement instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called measurement categories.
CAT I Secondary electrical circuits connected to an AC electrical outlet
through a transformer or similar device.
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 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 primary 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.

────────────────────────────────────────────────────
────────────────────────────────────────────────────
WARNING Before turning the product on, make sure the source voltage
matches that indicated on the product's power connector.
Connection to an improper supply voltage may damage the product
and present an electrical hazard.
To avoid electric shock and ensure safe operation, connect the
power cable to a grounded (3-contact) outlet.
The 3522-50 contains certain interior components which are at very
high voltages. Never remove the cover of the unit, because to do so
is very dangerous.
CAUTION Various connectors are present on the outside of the 3522-50. Never
connect any cable to any of these connectors without first turning off the
power supply and removing the power cord. Moreover, check the
connections carefully in order to avoid any chance of setting up a short
circuit etc..
If anything unusual happens during operation of the unit, turn off the
power switch immediately and contact any HIOKI service facility for help,
advice and service.
This product should be installed and operated between 0 and 40 and
80% RH or less, and less than 2000 m height.
The unit should always be stored in a range of temperature and humidity
from -10 to 55 , 80% RH or less.
Do not store or use the product where it could be exposed to direct
sunlight, high temperature or humidity, or condensation. Under such
conditions, the product may be damaged and insulation may deteriorate
so that it no longer meets specifications.
To avoid damage to the product, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.
Do not use excessive force on the touch panel, and do not use sharp
objects that could damage the touch screen.
Before using the product, make sure that the insulation on the probes is
undamaged and that no bare conductors are improperly exposed. Using
the product in such conditions could cause an electric shock. Replace the
test leads and probes specified by Hioki.
Ventilation holes for heat radiation are provided on the side panels of the
product. Leave sufficient space around the ventilation holes and install
the product with the holes unobstructed. Installation of the product with
the ventilation holes obstructed may cause a malfunction or fire.
Points for Attention During Use
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
About the guarantee
You should be aware that HIOKI cannot accept any responsibility directly or
indirectly if the unit has been incorporated in some other system, or if it is
resold to a third party.

Overview
1.1 Product Overview
The HIOKI 3522-50 LCR HiTESTER is an impedance meter which uses a
touch panel as the user interface. This interactive touch panel enables
extremely easy operation. The test frequency can be set DC and from 1
mHz to 100 kHz at high resolution.
The values of a maximum of any four of the fourteen test parameters,
including not only impedance |Z| and phase angle θ, but also L, C, and R
etc., can be simultaneously displayed upon the screen.
Moreover, this widely applicable impedance meter can be set, not only to a
floating voltage setting, but also to a constant voltage setting or a constant
current setting.

1.2 Product Features
────────────────────────────────────────────────────
1.2 Product Features
Wide range of test frequencies
The test frequency can be selected from a wide range - DC, 1 mHz to 100
kHz - at high resolution. Frequency dependent assessment of electronic
components and materials, etc., is possible.
Constant voltage and constant current testing
Assessment of dependence upon voltage or current is possible.
Outstanding operability
All control operations are initiated via a touch panel on the display. All the
keys currently available for use are shown on the display, and can be
operated interactively.
Simultaneous display of four parameters
Up to four of the test parameters (such as L,C,R, etc.) can be displayed
simultaneously.
Interface
Using a computer, any required parameters can be captured
Changing settings without stopping measurement
Various background settings can be changed without stopping measurement
(when an internal trigger is set).
