HIOKI DT4224 Digital Multimeter
Pocket DMM that Prevents False Circuit Breaker Trips using Proprietary Technology

OVERVIEW

The Hioki DT4200 Digital Multimeter Series consists of a diverse array of meters ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The Hioki DT4224 is a pocket-sized digital multimeter featuring an innovative circuit-breaker false trip prevention function to enhance testing safety, capacitance and diode testing functions, ideal for all general electrical jobs.

CAT IV 300 V, CAT III 600 V

Introduction of voltage input protection functionality
This functionality keeps errors in instrument configuration from resulting in an electrical accident. Even if the instrument’s rotary switch is mistakenly set to the resistance function when attempting to measure voltage, placing the probes in contact with the circuit under measurement will not cause a tripped circuit breaker or electrical arcing.

Key Features

Achieving a high level of safety in a compact body and lightweight design
Circuit breaker false trip prevention function helps avoid accidents resulting from breakers that mistakenly trip due to incorrect input
More convenient function: Resistance, Capacitance measurement and diode testing (DT4224)
Robust design capable of withstanding a drop from a height of 1 m
Test leads conveniently wrap around the back
±0.5% DC V basic accuracy, wide 40 Hz to 1 kHz AC V frequency characteristics
Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)
Broad -10°C (14°F) to 65°C (149°F) operating temperature range
Display backlight
