Field-Proven Strength and Usability
DT4200 series
Robust design capable of withstanding a drop from a
height of 1 m onto concrete
Fast, accurate measurement of the output voltage on the
secondary side of an inverter
Outstanding viewing angle so display is easy to read at
an angle or even in a dim location
Hand-free and easy to use New L9300 test leads with integrated cap*
Extensive selection of probe tips that you can choose based on the measurement location, improving ease of measurement
True RMS measurement for accurate measurement of
even distorted current waveforms
Rotary switch that’s easy to operate even when
wearing gloves
The DT series can accurately measure the voltage on the secondary
side of an inverter, just like a power meter. Its low-pass lter rejects
harmonic components so that the fundamental wave can be
isolated and accurately measured.
Current waveforms are often distorted, causing the average-value
and true RMS measurement methods to yield different results. To
obtain accurate readings, RMS measurement is indispensable.
Preventing instrument failure by keeping out dust
With screw terminals In deep-set locations
that can’t be reached
with other probes
For clamping around the
target busbar
To test our products’ ability to
withstand mechanical shock,
we repeatedly drop them from a
height of at least 1 m until they
break. This drop-testing regime
leads to more robust products
by fostering a series of design
improvements.
If dust gets into the instrument’s
enclosure, it can cause the device to
fail. Since dust can get into the
instrument especially easily through
the gap around the rotary switch, the
DT4200 series incorporates a
dust-proof part known as an O-ring
where the rotary switch is mounted to
improve the device’s dust resistance.
It’s hard to carry out work tasks smoothly when
you’re juggling a measuring instrument, probes,
recording paper, and other supplies. Field concerns
like these are resolved by the DT4200’s magnetic
strap, auto-hold function*, and ability to save results
in its internal memory. These capabilities boost work
efciency and help reduce work times.
*The auto-hold function is available exclusively in high-
end, standard models and DT4261,DT4223,DT4224.
The ability to save results in internal memory is available
exclusively in high-end models.
*Standard accessory for DT4261
*Compatible probe tips vary with the DMM model. Please
see page 16. The optional Connection Cable L4930 is
required in order to use the probes shown at the left.
The DT4200 series features a display
with a wide viewing angle and a
backlight function so that it’s easy to
read, even when you can’t view the
screen from the front or when making
measurements in a dim location.
With the DT4200, you can choose the
probe type that best suits your
measurement location, making it possible
to measure in areas that can’t be reached
with conventional probes and busbars that
you wish to clamp between probes.

The DT4200’s rotary switch is
designed to be easy to turn even
when wearing thick work gloves, for
example while working in
hazardous measurement locations
or harsh conditions.
Test leads L9300 now incorporate
integrated caps. The design lets
you change the measurement
category simply by sliding the test
lead’s protective nger guard.
As an added bonus, you no longer
have to worry about losing caps!
