HT401 HT Instruments Multimeter

The HT401 is a 3.75 digit handheld multimeter from HT Instruments. A multimeter is an instrument used to test and measure alternating current (AC) or direct current (DC) voltage, resistance, and electric current. Multimeters combine voltmeters, ammeters, and ohmmeters. Electricians use multimeters to run diagnostics on batteries, switches, components, power sources, and motors.

The HT401 is a TRMS digital multimeter designed to perform basically AC/DC voltage measurements up to 1000V, AC/DC current measurement up to 10A more than resistance, continuity test, diode test, frequency, capacitance, and temperature with type K probes as sub-features. Some relevant features are also the AC+DC mode which can be used to consider the DC components overlapped to a generic alternate signal and the AC/DC voltage measurement with low input impedance in way to reduce the capacitive influence of adjacent conductors during a voltage test.

The meter is designed in compliance with IEC/EN 61010-1 safety standard with double insulation protection in CAT IV 600V and CAT III 1000V. HT401 have a LCD display with bargraph and each measurement function can be selected with a rotate selector which permits also to avoid wrong connections. Other features are HOLD function, MAX/MIN/PEAK functions and Auto Power OFF feature is integrated to preserve the internal battery after 20 minutes of idleness.
