Keysight Technologies U1250 Series Handheld Digital Multimeters Data Sheet Test more - more safely The Keysight Technologies, Inc. U1250 Series handheld digital multimeters (DMMs) exceed your expectations by delivering powerful features and performance that meet your toughest requirements and applications. The series latest multimeters, the offering capabilities and functions you need. Key Features -- Superior contrast from organic LED (OLED) display1 -- 50,000-count dual display -- Up to 0.025% basic DCV accuracy -- True-RMS AC and AC+DC2 measurements -- K-type and J-type2 temperature measurements -- Manual and automated (interval) data logging; internally to DMM and externally to PC -- CAT III 1000 V and CAT IV 600 V safety protection -- Built-in 20-MHz frequency counter2 -- Built-in programmable square-wave generator2 [1] U1253B model [2] U1252B/U1253B models Do More with Just One Instrument The basic model, U1251B, expands your capabilities beyond typical DMM measurements to include data logging. The U1252B starts with the same foundation, and then adds a 20-MHz frequency counter and programmable square-wave generator-- so you'd be able to perform more tests conveniently with one tool. What's more: both models come bundled with a complete set of accessories to equip you right from the start at no extra cost. Offering the same functionality as the U1252B, the U1253B is the world's first OLED handheld DMM. You won't have to squint to be sure you're reading it right: On the go or on the bench, you'll get crystal-clear viewing indoors, even in dark, off-angle situations. Find Problems Quickly Troubleshooting can be tricky, especially when you're dealing with elusive problems. With the U1250 Series'data logging capability, you can ensure that every reading gets recorded manually or at intervals you specify. Better yet: you can have virtually unlimited data logging saves when you connect any of the U1250 Series DMM to a PC with the optional IR-to-USB cable. In addition, the U1250 Series lets you achieve greater confidence in your measurements with accurate true-RMS AC measurements, low DCV error rate of up to 0.025% and high-resolution display of 50,000 counts. Uncompromising Ruggedness and Safety The U1250 Series DMMs are housed in robust overmold enclosures, rated at CAT III 1000 V and CAT IV 600 V and operate over a wide temperature range of -20 C to +55 C. Each DMM also include a 30 kA high energy fuse to further protect you against violent fuse failures during highcurrent measurements. Built tough and certified to stringent industrial standards, the U1250 DMM is what you need to face the demands of everyday tasks. Figure 1.

[6] Always use the NULL function to zero out thermal effect with open test lead before measuring the signal. If the NULL function is not used, an additional 20 counts needs to be added to the DC current accuracy. Thermal effect could occur due to the following: - Wrong operation to measure the high voltage of 50 V ~ 1000 V for resistance, diode, and mV measurements. - After battery-charging has completed. - After measuring a current greater than 440 mA, it is suggested that the meter be left to cool down for twice the measuring time used. [7] Current can be measured up to 10 A continuously. An additional 0.5% needs to be added to the specified accuracy if the signal measured is in the range of 10 A~20 A for 30 seconds maximum. After measuring a current of > 10 A, leave the meter to cool down for twice the measuring time used before application of low current measurement.
