DESCRIPTION

The 400-014 is an auto-ranging professional digital multimeter featuring a 3¾-digit LCD display (4,000 counts) with a large 45×25 mm window for clear readability. It provides comprehensive measurement capabilities including DC voltage (400 mV to 1000 V), AC voltage (4 to 750 V), DC current (400 µA to 10 A), AC current (400 µA to 10 A), resistance (400 O to 40 MO), capacitance (4 nF to 100 µF), frequency (10 Hz to 20 MHz), and temperature (-20°C to 100°C). The meter features high sensitivity of 100 µV, 10 MO impedance on all DCV and ACV ranges, auto power-off after 20 minutes of inactivity, and protective functions including PTC, two fuses, and diode protection on current, resistance, and voltage ranges. Additional capabilities include continuity testing with buzzer, transistor testing, diode testing, LED checking, and data hold function. This multimeter is ideal for technicians and engineers requiring reliable measurements in field service, maintenance, troubleshooting, and laboratory applications.
