UNI-T UT139C True RMS Digital Multimeter

This instrument is a 6000 counts hand-held automatic range True RMS digital clamp meter. The circuit design of the meter takes the large-scale integrated circuit ∑/△ analog-to-digital converter (ADC) as the core, and it has the full-range overload protection. It can be used to measure AC and DC voltage, low-pass filter V.F.C, low-impedance Low Z voltage, AC and DC current, resistance, diode, continuity test, capacitance, frequency, duty cycle, temperature and other parameters, at the same time, it has the data hold, relative value measurement, surge current measurement function, flashlight function, NCV function, Live line judgment, low voltage display and automatic shutdown function.

• 3-Pole and 2-Pole Earth Resistance
• The latest circuit design permits the instrument to operate with the minimum of influence from earth voltage and earth resistance of auxiliary earth spikes
• Dust and drip proof (designed to IEC 60529 IP54)
• Large, easy-to-read LCD digital display.
• Designed to meet IEC 61010-1 safety standard
• Capable of measuring earth voltage
• Small and lightweight. Shock-resistant new case material
• 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test

Key Features

• Measures AC/DC with included iFlex current probe
• VFD low-pass filter for accurate measurements of non-linear signals
• Remotely log, trend, and monitor to pinpoint intermittent faults
• Inrush measurement to filter out noise and capture the starting current

The 117 digital multimeter is a for electricians working in commercial and non-commercial premises that need non-contact voltage detection for faster and safer operations.

• Non-contact voltage detection
• AutoVolt automatic AC/DC voltage selection
• Prevent false readings caused by ghost voltage
