02 | Keysight | U1240B Series Handheld Digital Multimeters - Data Sheet
Keysight Technologies, Inc. U1240B Series handheld digital multimeters enable you to
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
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
differential temperature capabilities, with just a press of the button. The meters have a
high safety rating with CAT III 1000 V and CAT IV 600 V protection and are certified to
CE and CSA standards. On top of that, the U1240B Series comes with a certificate of
calibration and test report – at no extra cost.
The latest multimeters in this series, the U1241B and U1242B, now come in vivid orange
cases, offering the capabilities and functions you need.
