Measuring Instruments

The Long-Awaited Bench-type Model Is Here !

Leakage Current Measurement Essential

for Electrical Safety

Because of the risks it poses, many standards stipulate leak

current test methods, the performance of test equipment, limits

for leak current, and other factors related to leak current. The

bench-type 3156 LEAK CURRENT HiTESTER by itself, without

any additional equipment, is capable of performing tests that

comply with s tandards for a wide range of equipment, from

ge ne ra l p urp os e e le c tric a l e q uip me nt to me d ic a l e le c tric a l

equipment. The 3156 also is equipped with functions and an

interface that support embedded test lines.

HIOKI company overview, new products, environmental considerations and

other information are available on our website.

Automatically compatible with Networks

stipulated by IEC/UL/JIS standards

In order to avoid dangers such as electric shock,

electrical equipment is designed so that those

portions that are likely to be touched by people

Main Fe ature s

are insulated from the power source. However,

the insulation resistance is not infinite, so there is

always some leak current present. Furthermore,

the extent of the leak current changes over time

as the insulation deteriorates. To determine their

safety level, the 3156 LEAK CURRENT HiTESTER

can prove to be highly valuable, both as a tester

on the production line as well as a maintenance

and inspection tool.

ꢀꢀStandard support for a variety of Networks

The 3156 is engineered to automatically support the

"Networks" (human simulated resistance) stipulated by

the various international safety standards. Switch

between Networks or use the filters using a PC.

ꢀꢀMeasurement that complies with standards

The 3156 by itself can measure leak current in compliance

with IEC, UL, and JIS standards.

ꢀꢀAutomatic measurement function

ꢀꢀRS-232C, GP-IB, and EXT I/O interfaces

standard

Because the 3156 is equipped with several standard

interfaces, it is easy to set up for automatic inspection on

a production line, etc. In addition, the RS-232C port can

be used to connect the optional 9442 Printer for easy

print-outs.

The 3156 is capable of automatically measuring power

supply polarity switching as well as the normal state/single

failure state, and can display the maximum values. The

measurement time and the wait time can be set by the user.

ꢀꢀStores data for 100 units

The 3156 can store data such as equipment name, control

number, ground class, and measured values for up to 100

pieces of equipment being tested.

ꢀꢀSave up to 30 sets of measuring conditions

The 3156 can save and load up to 30 different sets of

measuring conditions, and can switch between different

sets quickly.

ꢀꢀPower supply separation

The power supply for the 3156 is separate from the line

power supply of the equipment being tested, preventing

damage to equipment due to wrong supply voltage being

input.

Simple operation in an interactive format

The 3156 is equipped with a touch panel that can

be used to make settings simply by touching the

items to be selected on the display, making

operation even more simple.

110% voltage application terminals

The 110% voltage application terminals are used when testing

medical equipment. It outputs on a 1:1 basis the voltage that is

supplied to the line power supply for the equipment being

tested. The polarity of the connectors can be switched.

Breaker for equipment being tested

Since the 3156 is a bench-type unit that is suited

embedded test lines, it is equipped with a terminal

board and breaker on the front panel, allowing

test equipment to be easily connected to the 3156

even when it is rack mounted.

Based on the settings for the Network and

the equipment being tested, the 3156 displays

the appropriate meas urement mode. The

state of the settable keys can be seen at a

glance. All settings can be made by selecting

the appropriate items or values.

ꢀꢀWiring check functions

ꢀꢀSupport for proprietary networks

The 3156 performs polarity

checks and VA checks.

When making measurements on a proprietary network that is

not built into the 3156, the

3156 can be used as a true

effective value ammeter in the

1MHz band.

ꢀꢀBrowsing saved data

The 3156 allows the user to

browse all saved data. Saved

data can also be printed out

or downloaded to a computer.

Single failure setting

The single failure status can be set for

individual items in automatic testing, with

continuous testing performed automatically

only for the items for which the single failure

setting was made. In addition, the wait time

and measurement time can also be set.

Leak current measurement

for general equipment

The ne twork (huma n s imula te d re s is ta nc e ) is

specified separately in each standard, and when

taking measurements a network that is suited to

the standards is needed. The 3156 is pre-engineered

with bas ic Networks that corres pond to each

standard.

enclosure, through an external conductor other than the protective ground.

EXT I/O

Separation of the power supply for the 3156 and

the line for the equipment being tested

The power supply voltage for the 3156 does not need to

be changed, even if the supply voltage for the equipment

being tested is different. The difference can be managed

by controlling the line supply voltage for the equipment

being tested. This helps prevent malfunctions due to the

wrong voltage being input for the 3156 power supply.
