Measurement Categories
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. These are defined as follows.
Using a measurement product in an environment designated with a higher-num-
bered category than that for which the product 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 mea-
surement applications could result in a severe accident, and must be carefully
avoided.
Accuracy We define measurement tolerances in terms of rdg. (reading) and dgt. (digit) values,
with the following meanings:
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 installa-
tions) 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).
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.

Operating Precautions
4
Follow these precautions to ensure safe operation and to obtain the full benefits
of the various functions.
Preliminary Checks• Before using the unit the first time, verify that it operates normally to ensure
that the no damage occurred during storage or shipping. If you find any dam-
age, contact your dealer or Hioki representative.
• Before using the unit, make sure that the insulation on the probes and cables
is undamaged and that no bare conductors are improperly exposed. Using the
unit in such conditions could cause an electric shock, so contact your dealer
or Hioki representative for replacements.
Operating Temperature and Humidity: 0 to 40°C, 80%RH or less, no condensa-
tion
Storage Temperature and Humidity: -10 to 55°C, 80%RH or less, no condensa-
tion
Accuracy-guaranteed temperature and humidity ranges: 23±5°C, 80%RH
Operating Precautions
Unit Installation
Avoid the following locations that could cause an accident or damage
to the unit.
Exposed to direct sun-
light
Exposed to high tem-
perature
In the presence of cor-
rosive or explosive
gases
Exposed to liquids
Exposed to high hu-
midity or condensa-
tion
Exposed to strong
electromagnetic fields
Near electromagnetic
radiators
Exposed to high lev-
els of particulate dust Subject to vibration

Operating Precautions
5
Installing • Do not install the unit with any side except the bottom facing down.
• Vents must not be obstructed.
OK
10 cm or more
5 cm or more
• Do not allow the instrument to get wet, and do not take measurements
with wet hands. This may cause an electric shock.
• Never modify the unit. Only Hioki service engineers should disassem-
ble or repair the unit. Failure to observe these precautions may result
in fire, electric shock, or injury.
Handling this device
• 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.
• To avoid damage to the unit, protect it from physical shock when transporting
and handling. Be especially careful to avoid physical shock from dropping.
This instrument may cause interference if used in residential areas. Such use
must be avoided unless the user takes special measures to reduce electro-
magnetic emissions to prevent interference to the reception of radio and televi-
sion broadcasts.

Operating Precautions

About the guarantee
You should be aware that HIOKI cannot accept any responsibility directly or indi-
rectly if the unit has been incorporated in some other system, or if it is resold to a
third party.
• Before turning the unit on, make sure the supply voltage matches that
indicated on the its power connector. Connection to an improper sup-
ply voltage may damage the unit and present an electrical hazard.
• The power supply voltage for this unit is switchable. To avoid electrical
accidents, check that the voltage selector is set correctly for the supply
voltage you are using.
See Setting Procedure for the Power Voltage : 2.2 "Checking the Power Voltage" (p.
18)
• To avoid electrical accidents and to maintain the safety specifications
of this unit, connect the power cord provided only to a 3-contact (two-
conductor + ground) outlet.
See Connection Procedure : 2.3 "Connecting the Power Cord" (p. 19)
• To avoid shock and short circuits, turn off all power before connecting
probes.
Check the connections carefully in order to avoid any chance of setting
up a short-circuit etc.
Before connection and powering on

1.1 Product Overview

1
The HIOKI Model 3506-10 C Meter are capacitance meters employing 1 kHz
and 1 MHz frequencies to measure large-value multilayer ceramic capacitors
with constant voltage at high speed and high accuracy. Primary applications
include pass-fail judgment and ranking of capacitors on tape machines and sort-
ers.
These capacitance meters use 1 kHz and 1 MHz measurement frequencies.
The 3506-10 are capable of high-speed measurement: 1.5 ms at FAST.
Capacitors are easily ranked according to C (Capacitance*1) measurement val-
ues into as many as 13 classifications.
Makes pass-fail judgment of components based on C measurement value and D
(dissipation factor*2), or on Q (quality factor*3) measurement value.
Provides superior visibility.
The 3506-10 offers external I/O for sequencing, a standard RS-232C interface,
and a standard GP-IB interface.
Up to 1000 measurement values can be stored in memory.
*1. Capability to store electric charge.
*2. An indicator of capacitor losses.
*3. An indicator of capacitor purity.
