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
CAT III
CAT IV
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.
Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to
outlets.
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.
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.
The specifications in this manual include figures for "measurement accuracy"
when referring to digital measuring instruments, and for "measurement
tolerance" when referring to analog instruments.

dgt.
(maximum display or scale value, or length of scale)
Signifies the maximum display (scale) value or the length of the scale
(in cases where the scale consists of unequal increments or where the
maximum value cannot be defined).
In general, this is the range value (the value written on the range
selector or equivalent) currently in use.
(displayed or indicated value)
This signifies the value actually being measured, i.e., the value that is
currently indicated or displayed by the measuring instrument.
(resolution)
Signifies the smallest display unit on a digital measuring instrument,
i.e., the value displayed when the last digit on the digital display is
"1".
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
To avoid any life-threatening electric shock accidents, ensure that the
DANGER
following rules are observed.
The Insulation/Withst anding Hitester is a dangerous product which
discharges high voltages. To prevent getting electrocuted, always
wear high-voltage protective rubber gloves when carrying out any
operation.
Be careful when using the product and ensure that you do not touch
this product, any tested object that is connected or any H.V. TEST
LEAD, etc.
To avoid electric shock, do not remove the product's case. The
internal components of the product carry high voltages and may
become very hot during operation.
The vinyl shield on the 9615 H.V. TEST LEAD alligator clip is not high
voltage insulated. Do not touch when high voltage is applied.
WARNING
CAUTION
To avoid electric shock, do not allow the product to get wet, and do
not use it when your hands are wet.
To avoid electric shock, be sure to connect the protective ground
terminal to a grounded conductor.
To avoid electrical accidents and to maintain the safety specifications
of this instrument, connect the power cord provided only to a 3contact (two-conductor + ground) outlet.
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.
Replace the fuse only with one of the specified characteristics and
voltage and current ratings. Using a non-specified fuse or shorting
the fuse holder may cause a life-threatening hazard.
Fuse type: 250VT8AL (3159, 3159-01), 250VT4AL (3159-02 to 3159-04)
To avoid electrocution, turn off the power to all devices before plugging or
unplugging any of the interface connectors.
To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging the cord from the power outlet.
To avoid damaging H.V. TEST LEAD, do not kink or pull on the leads.
For safety reasons, when taking measurements, only use the H.V. TEST
LEAD provided with the product.
To avoid damage to the product, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.
Failure to observe the following precaution may result in bodily injury.
This instrument weighs approximately 18 to 21.5 kg. When lifting or
moving the unit, it is strongly recommended that two capable persons
hold the instrument at both ends of the bottom to prevent drop or
damage.
The instrument is heavy. When transporting it, follow your company's
workplace safety standards to assure safety (for example, by wearing
non-slip gloves and protective footwear).
To avoid electric shock, do not exceed the lower of the ratings shown on
the instrument and test leads.
Do not use the product near a device that generates a strong electromagnetic field
or electrostatic charge, as these may cause erroneous measurements.
This product may cause interference if used in residential areas. Such use must be
avoided unless the user takes special measures to reduce electromagnetic
emissions to prevent interference to the reception of radio and television
broadcasts.
With the unit insulation resistance and withstand voltage tests based on a
wide variety of standards can be performed. The timer and comparative
screening functions using the upper- and lower-limit values provide accurate
test results. When testing withstand voltage, the unit does not operate until
the output-voltage preset using the voltage adjustment knob is within5%
(output-voltage1 kV:50 V) of the comparative-voltage value, thus
ensuring more accurate readings.
(2) Automatic insulation resistance testing and withstand voltage
testing
The Auto Test mode allows consecutive insulation resistance and withstand
voltage tests to be performed.
(3) Fluorescent indicator
The large, easy-to-read fluorescent display permits quick checking of the
testing state and result.
(4) Analog Voltage Measurement
The voltage is digitally displayed on the fluorescent indicator. This value can
also be checked on the analog voltmeter. (withstand voltage test only)
(5) Saving testing set values (Memory function)
This unit is provided with a function for saving the set values used in a test,
allowing quick switching between different testing set values to meet a
variety of standards and regulations. Up to 10 values may be saved for each
testing mode.
The values immediately prior to a power shutdown are saved in the unit.
These values are valid at the next startup.
(6) REMOTE CONTROL BOX
The 9613 REMOTE CONTROL BOX (SINGLE) or the 9614 REMOTE
CONTROL BOX (DUAL) can be connected to the external switch terminal
to perform 3159 start/stop control.
