    The Keysight Technologies U1250A series handheld digital multimeter gives you 4.5 digit resolution with a 50,000 count full scale and basic DC voltage accuracy of up to 0.025%. These features give you the flexibility to perform quick validation measurements or perform tolerance checks and marginal failure troubleshooting. It also offers true RMS, dBm, and AC+DC readings to measure both sinusoidal and nonsinusoidal waveforms accurately.

    Versatile functionality

    The U1250A series handheld digital multimeter delivers many features that you would expect from a benchtop multimeter. These instruments come with all the basic measurement functions and added functionality needed in today's changing maintenance environment such as temperature measurements, frequency measurements, 4-20 mA process loop measurement with % readout, 20 MHz frequency counter (U1252A only), and dBm measurements.

    More than just a measurement tool

    The U1250A series expands users' capability beyond typical measurements. These instruments provide data storage capability which can be done both manually or automatedly with the optional PC interface cable. The accompanying Keysight Technologies Graphical User Interface (GUI)further extends the potential of these instruments by allowing you to customize your data logging needs. Other features include sophisticated math functions that allow users to manipulate the data obtained. The U1252A can be used as a programmable square wave generator that allows you to stimulate electronic circuits for debugging purposes.

    Uncompromising ruggedness and safety

    Use The U1250A series handheld digital multimeter with confidence in almost any environment. These instruments come in a robust package with shock absorbing overmold and operate within their rated specifications from -20 ° C right up to +55 ° C. Furthermore, these instruments are rated at Cat III 1000 V (IEC 61010 Compliant) which allows you to confidently make measurements on building electrical installations, at locations between the main circuit breaker and the mains socket-outlets, including measurements performed onequipment that is permanently connected to the mains circuits.
