Data Sheet

Perform Test Confidently and Efficiently Over a Longer Period of Time!

Introduction

For technicians or industrial test engineers, their ultimate goal is to keep the production line running seamlessly to prevent unplanned shutdown. The strong and solid U1240C Series handheld digital multimeters (DMMs) are the tools you need to work efficiently. Certified to IP 67 and capable to withstand up to 3-meter (10 feet) drop to suit harsh working environments, these durable DMMs can even work longer for you with up to 400 hours of battery life. Better yet, you can optimize productivity with the unique remote data logging functionality designed to work together smoothly. Perform test confidently and efficiently — everything you need to get the job done.

Test Confidently and Efficiently

Harmonics ratio

Regular maintenance to keep the production line running seamlessly is the ultimate goal for industrial test engineers. In real life there is the presence of harmonics due to many electronic devices powered by switched mode current pulses that travels back into the power source. If these unwanted harmonics become too large, they have unwanted side effects: overheating that shortens the lifespan of motors, generators and transformers; premature tripping of circuit breakers; and blown fuses. Hence an accurate, dependable U1240C Series DMM helps to ensure early detection of harmonics in the AC supply. One of the fastest ways to detect and gauge the percentage of distortion due to harmonics is by measuring the harmonic ratio of the incoming AC voltage.

The U1240C Series offers a fast one-button check with its harmonic ratio function. The ratio percentage helps you to decide if further analysis of the power source is required with an oscilloscope or a spectrum analyzer.

Low impedance mode

Stray voltages are usually encountered in non-energized electrical wiring adjacent to powered wires due to capacitive or inductive coupling between these wires. The low impedance mode helps to reduce false readings by dissipating these stray voltages thus improves safety and measurement efficiency during voltage measurement.

Vsense for non-contact voltage detection

The U1240C Series handheld DMM have Vsense — a unique method of non-contact voltage detection that safeguards users from exposure to hot or live wires while making measurements in dangerous working environments. Upon detection of voltage, it produces a unique combination of beeping alert and blinking LED light to alert users. This feature is especially useful to make measurements more efficiently in dark or noisy environment.
