Keysight Technologies U1240B Series Handheld Digital Multimeters Data Sheet02 Keysight U1240B Series Handheld Digital Multimeters - Data Sheet Keysight Technologies, Inc. U1240B Series handheld digital multimeters enable you to Key Features check more with wider measurement ranges. They feature true RMS readings on their 10,000-count displays. The adjustable backlighting allows you to complete your jobs Check more, fix more even in subdued lighting conditions, or to simply prolong battery life. Your maintenance tasks are greatly simplified due to the built-in switch counter, harmonic ratio, dual and 10,000-count display differential temperature capabilities, with just a press of the button. The meters have a 0.09% basic DCV accuracy high safety rating with CAT III 1000 V and CAT IV 600 V protection and are certified to True RMS AC measurement CE and CSA standards. On top of that, the U1240B Series comes with a certificate of Basic functions ACV, DCV, ACI, calibration and test report at no extra cost. DCI, resistance, frequency, diode, continuity tests The latest multimeters in this series, the U1241B and U1242B, now come in vivid orange Advanced functions cases, offering the capabilities and functions you need.
