1.1 Product Overview and Features
This instrument employs the 4-terminal method to quickly and accurately measure the DC resistance of
components, such as resistors and ferrite beads.
It includes advanced contact-check, comparator, and data output functions. The intuitive user interface
and high noise immunity are ideal for use with taping machines and separators.
Resistance Measurement
The factory defaults (initial settings)
are optimized for chip-component re-
sistance measurements. It can also
measure devices that are otherwise
difficult to measure with a high cur-
rent, such as ferrite bead and small
multilayer inductors (low-power re-
sistance measurement) (p. 28).
It is also suitable for measuring impe-
rial 008004 sized components with
small rated voltage (Applied Voltage
Limit Function) (p. 64)
Interface Communications
Connect the instrument to a con-
troller via the RS-232C or GP-IB
interface to control this instru-
ment or acquire the measure-
ment data
(p. 109)
Send the measurement value
and calculation results to the
printer.
Use a commercially available print-
er with a serial interface to print the
measurement values and calcula-
tion results. (p. 89)
Save and Output the Mea-
surement Values
Measurement values can be stored
in the internal memory (p. 79).
Statistical calculations can be per-
formed on the stored data, which
can be transferred to a computer in
batch form (however, stored data
cannot be confirmed internally).
Judge the Measurement Values
Measurement values are compared
with a pre-specified reference value
or range, and the result is outputted
externally and indicated by the
COMP indicators (comparator func-
tion) (p. 36)
Connect a PLC or I/O Board
By connecting to the EXT. I/O con-
nector, it is possible to control the
instrument from a PLC. In addition
to the comparator results, various
measurement anomaly signals
can be outputted. (p. 95)
Upper limit
Lower limit
When using two instruments, a differ-
ence in settings disables measure-
ment and causes a warning
notification (Setting Monitor Function)
(p. 59).
Optional Hioki probes and fixtures are
available to con-
nect to the mea-
surement jacks
(BNC jacks
(p. 5)).
Alternatively,
commercially
available cables,
such as the 1.5D-
2 V coax, can be
used (p. 24)
