Comparator function provides PASS/FAIL decisions at a glance
 The comparator function compares measured values to pre-set reference values to generate a
pass or fail judgment. (Can be used with insulation resistance measurement and low-resistance measurement.)
 The stable display is easy to read, increasing work efficiency.
Instant judgment
Identify PASS/FAIL using light and sound
Since the IR4056-20 and IR4057-20 generate judgments
as soon as the test lead makes contact, it is possible to
make a rapid series of measurements in the manner of a
continuity check.
The IR4056- 20 and IR4057- 20 notify the operator of pass and fail
judgments using a beeping sound, LCD light, and comparator indicator
on the test lead with remote control switch (optional accessory), allowing
determinations of compliance to be made without looking at the instrument.
PASS
Option
When the measured value
is greater than or equal to
the reference value*
Short beep
No change
Useful when there are
numerous measurement
locations
*In some cases, the capacitance component may prevent a judgment from
being made until charging completes.
FAIL
Green
Option
When the measured
value is less than the
reference value*

Use as a tester replacement thanks
to DC voltage measurement
functionality, which is useful in
applications involving solar power
and electric vehicles (EVs).

Easy-to-see LCD
An FSTN LCD ensures the instrument’s
display is easy to read from any angle.
Effective maximum display value
A “>” mark is displayed when the
measured value is greater than the
effective maximum display value for the
function in use.
