It’s extremely dangerous to measure a commercial power supply with an instrument set to the resistance range (used to measure continuity, capacitance, and diodes). Doing so can cause electrical equipment to stop operating due to tripped circuit breakers or result in arcing.

The Hioki DT4223 Digital Multimeter prevents potential hazards that can be caused by erroneous instrument operation with a one-of-a-kind design. With the DT4223 the measurement circuit is switched after the instrument detects resistance, or continuity. Even if you mistakenly input voltage with the instrument set to the resistance range, the high input impedance will limit the current flowing to the instrument to 1.5 mA or less to prevent potential hazards. When the DT4223 detects resistance, or continuity, the LoZ icon is shown on the display, allowing you to identify at a glance which measurement circuit has been selected.

Features for Greater Ease of Use

Operating Temperature

-10° to 65° Operating Temperature Range
The Hioki DT4223 can be used in a wider range of environments, including at subzero temperatures and on scorching hot summer days.

Auto Hold

Auto Hold for Easy Checking of the Display
The Display value is automatically held once measured values stabilze.

Visual Warning

Visual Warning Function
A red backlight warns you of excessive voltage input, facilitating visual confirmation in noisy settings.

Compact and lightweight design for outstanding ease of use

The small form factor fits in your hand perfectly and is easily stowable, making it convenient to transport to and from the field and boosting work efficiency. The lightweight design also ensures that the DT4223 is easy to work with.

Safe enough for measuring voltage at distribution panels and service wires

Despite a compact body, the DT4223 can be used to measure voltage at distribution panels and service wires in CAT III (600 V) CAT IV (300 V) situations.

Intuitive notification of excessively high input with flashing screen

The DT4223 multimeter notifies the operator of excessively high input by flashing the screen, making it possible to check measurement results intuitively.

Automatic Switching of measurements in locations where AC and DC voltages are mixed

When making measurements in locations with both AC and DC voltages, automatic switching eliminates the need to operate the rotary swich and helps prevent measurement mistakes.
