Keysight U1242B Series handheld digital multimeters are designed for users to perform tests confidently and efficiently over longer periods of time due to the precision, accuracy and repeatability. The U1242B digital multimeter is also designed to increase technicians or industrial test engineers production with the longer lasting battery life. The battery life will last up to 300 hours allowing you to work for longer periods of time without having to stop and battery change. The ergonomic shaped handheld digital multimeter has a large display and adjustable backlight that allows you to single handedly select measurements functions using the anti-slip rotary dial making it much easier for you to improve production whilst working in lower light environments. This digital multimeter also has an IP67 certified protection with the durability to withstand drops up to 10 feet to suit harsh working environments. This digital multimeter is designed for indoor use, in areas with low condensation and to be used with standard or compatible test probes. For improved safety the U1242B series digital multimeters also allow you to run continuity tests with visual (flashing backlight display) and audio (beeper) alerts and will also detect glitches swiftly with the built in switch/relay counter. This battery powered handheld digital multimeter features true rms readings with a 10,000 count, 4 digit display and analogue bar graph results without the complications. Another special feature of this digital multimeter is that it has harmonic ratio measurement to quickly identify the presence of harmonics in AC signals.

In real life, harmonics are present in AC power due to the fact that many electronic devices are powered by switched mode current pulses which travel back into the power source. If these unwanted harmonics become too large, the undesirable side effects include: overheating that shortens the lifespan of motors, generators and transformers, premature tripping of circuit breakers, and blown fuses. 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. You can perform this very easily on the U1242B handheld digital multimeter, with just a press of a button. The percentage helps you to decide if further analysis of the power source is required with an oscilloscope or a spectrum analyser.

Yes- Certificate of Calibration will be available.
