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
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.
Main Features
s
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.
s
Measurement that complies with standards
The 3156 by itself can measure leak current in compliance
with IEC, UL, and JIS standards.
s
Automatic measurement function
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.
s
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.
s
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.
s
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.
s
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.
Measurement mode
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.
