Card HiTester 3244 During measurement
Beep
DT4221 Immediate display of
measurement results
Automatic switching of
measurement in locations where
AC and DC voltages are mixed
Detect voltage simply by holding
the instrument against a wire
AC/DC voltage automatic detection (DT4221, DT4223 only) Voltage detection function (DT4221, DT4223 only)
Compact and lightweight design
for outstanding ease of use
The small form factor ts in your hand
perfectly and is easily stowable, making it
convenient to transport to and from the eld
and boosting work efciency. The
lightweight design also ensures that pocket
models are easy to work with.
When making measurements in locations
with both AC and DC voltages, automatic
switching eliminates the need to operate the
rotary switch and helps prevent
measurement mistakes.
Easily detect voltage with the built-in sensor.
Results are communicated with a beep.
Safe enough for measuring
voltage at distribution panels and
service wires
Fast measurement for outstanding
ease of use
Intuitive notication of excessively
high input with ashing screen
The pocket digital multimeters notify the
operator of excessively high input by ashing
the screen, making it possible to check
measurement results intuitively.
Despite a compact body, the pocket models
can be used to measure voltage at
distribution panels and service wires in CAT
III (600 V), CAT IV (300 V) situations.
Measured values are displayed quickly to
facilitate quick testing. The difference is
clear when you compare the measurement
speed with that of the Hioki Card HiTESTER
3244-60.
AC contacts
DC contacts
New DT4223 and DT4224 feature circuit breaker false trip prevention
Prevent potential accidents during
incorrect input
The measurement circuit switches only after
detecting the appropriate signal.This way,
even if you mistakenly input voltage, accidents
due to tripped breakers or arcs will not
happen. (see page 2)
Warning function
noties you of incorrect input.
The instrument’s display ashes red to warn
you when voltage has been mistakenly input
while the instrument is set to the resistance
range.
LoZ icon identies switched
measurement circuit
When the instrument detects resistance,
continuity, capacitance, or diode input, the
LoZ icon is shown on the display, allowing
you to identify at a glance which
measurement circuit has been selected.
