CAT IV 600V and CAT III 1000V IP67 Dust & waterproof with O-ring sealed casing NCV detection above 110V AC, LCD turns red to indicate presence of voltage Auto range with manual override Measures frequency range of 10Hz to 10MHz on electronic and electrical circuits Measures AC and DC voltage to 1000V Capacitance to 4000μF / Relative mode / Data hold MIN/MAX recording mode 6000 Count LCD display and equipped with a 61 segment analogue bargraph Full ranges protection & Auto power off Overmould rubber housing & Integrated test lead holder Blue backlight for dimly lit areas The MT1881 is a True RMS professional multimeter having a large 6000 count backlit LCD with a 61 segment analogue bar graph, especially designed for everyday use by electricians. Capable of measuring 1000V AC and DC, with added measuring ranges of Resistance, AC/DC Current, Capacitance and Frequency. The meter has been designed that should a user turn the rotary switch in any direction whilst an input of less than 1000V AC/DC is applied to the meter, the meter will not get damaged. NCV function, automatic Non-Contact voltage detection, the LCD backlight will glow red when AC voltage above 110V is sensed. The meter has a double moulded rubber case with IP67 waterproof and dustproof rating, rugged design for heavy duty use.   Specifications Function Range Resolution Accuracy DC Voltage 600mV – 1000V 1V ±(0.5% + 5 Digits) AC Voltage 6V – 1000V 1V ±(0.8% + 4 Digits) AC Voltage (VFD) 50V – 600V 0.1V ±(4.0% + 9 Digits) DC Current 600uA – 10A 0.01A ±(1.0% + 3 Digits) AC Current 600uA – 10A 0.01A ±(1.5% + 3 Digits) Resistance 600Ω – 60MΩ 0.01MΩ ±(0.8% + 2 Digits) Capacitance 60nF – 60mF 0.01mF ±(4.0% + 5 Digits) Frequency (Electronic) 9.999Hz – 10MHz 0.01MHz ±(1.0% + 5 Digits) Frequency (Electrical) 10 ~ 1KHz 0.0Hz ±(1.5% reading) Duty Cycle 0.1% – 99.9% 0.1% ±(1.2% + 2 Digits) AC Response True RMS Digital Display 6000 Count Bargraph 61 Segmented Continuity Test Audible signal if the resistance is approx. 50Ω or less Diode Test Test current 0.9mA typical, open circuit voltage 3.2V DC typical Non-Contact Voltage Detection above 110V AC, LCD display turns red Data Hold Yes Back Light Yes Enclosure IP67 Dust & Waterproof Double Moulded Battery 9V Dimensions 187 x 81 x 50mm Weight 342g Safety Ratings            Includes: 9V Battery Test Leads Instruction Manual Downloads MT1881 Technical Datasheet MT1881 Instruction Manual
