Description

Agilent U1252B Handheld Digital Multimeter, 4.5-digit

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.

Do More with Just One Instrument

The basic model, U1251B, expands your capabilities beyond typical DMM measure- ments 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 capabil- ity, 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 mea- surements 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 high- current measurements. Built tough and certiﬁed to stringent industrial standards, the U1250 DMM is what you need to face the demands of everyday tasks.

[1] Input impedance: Refer to Table A on page 9. [3] The accuracy of 500 Ω and 5 kΩ is speciﬁed after NULL function, which is used to subtract the test lead resistance and the thermal effect. [4] For the range of 50 MΩ and 500 MΩ, the R.H. is speciﬁed for <60%. [5] The accuracy is speciﬁed for <50 nS and after NULL function with open test lead. [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. [8] Maximum open voltage: <+ 4.2 V.

[1] All frequency counters are susceptible to errors. Shielding inputs from external noise pickup is critical to minimize measurement errors. For non-square wave signals, add 5 counts.
[2] Output impedance: 3.5 kΩ maximum.
[3] The positive or negative pulse width must be greater than 50 μs for adjustment of the duty cycle or pulse width under different frequencies. Otherwise, the accuracy and range will be different from the speciﬁcations deﬁned.
[4] For signal frequencies greater than 1 kHz, an addition of 0.1% per kHz is added to the accuracy.
[5] For data logging to PC, maximum number of data points is dependent on available hard disk space.
[6] For the U1253B model.
