Keysight U1242C 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 U1242C 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 400 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 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. Another feature to help you with poorly lit environments is that this digital multimeter has a built-in flashlight. The U1242C multimeter fits comfortable in your palm allowing you to single handedly illuminate test area with its easily activated built in LED flashlight. This digital multimeter also has an IP67 certified protection for water and dust protection with the durability to withstand drops up to 10 feet to suit harsh working environments. For improved safety the U1242C 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, Zlow impedance mode to eliminate false readings caused by stray voltages, Vsense for non-contact voltage detection and T1-T2 differential temperature measurements. Features ; Benefits. 10,000 - count dual display Up to 0.09% basic DCV accuracy CAT IV 600 V and CAT III 1000 V over-voltage protection Longer battery life up to 400 hours Auto ; Manual data logging - 2000 readings Certified to IP 67 for water and dust protection Tested to withstand a 3m (10ft.) drop Easy connectivity to PC with optional IR-USB cable or Bluetooth Frequency counter Built in Low pass filter for accurate VFD troubleshooting Harmonic Ratio Zlow impedance mode Vsense - Non-contact voltage detection alerts of hot or live wires. The U1242C series digital multimeter measures. AC/DC voltage ; current Resistance Voltage frequency Diodes Continuity Capacitance Temperature. Vsense for non-contact voltage detection. The Vsense, a unique feature found in the U1242C Series performs non-contact voltage detection. It delivers more safety while making measurements in dangerous working environments by avoiding any contact with hot or live wires, suspected AC voltage presence or simply and act of safety precaution before initiating a task. Upon detection of voltage, it produces a unique combination of beeping alert and blinking LED light to make measurements more efficiently – especially in a dark or noisy environment. Harmonics ratio. 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 U1242C handheld digital multimeter, with just a button press. The percentage helps you to decide if further analysis of the power source is required with an oscilloscope or a spectrum analyser.
