Datasheet for U1252B 50000 Count Handheld DMM

Agilent U1250 Series Handheld

Digital Multimeters

Data Sheet

Test more – more safely

The Agilent 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 U1251B, U1252B and U1253B come in vivid orange cases, offering capabilities and functions equivalent to the U1250A Series.

Key features

Do more with just one instrument

The basic model, U1251A/U1251B, expands your capabilities beyond typical DMM measurements to include data logging. The

U1252A/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 U1252A/

U1252B, the U1253A/U1253B is the world’s fi rst

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 confi dence 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

Figure 1: Automate recording of measurements with bundled

GUI data-logging software.

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 certifi ed 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.

[2] The accuracy could be 0.05% + 10 for U1251A and 0.05% + 5 for U1252A/3A. Always use the NULL function to zero out the thermal effect before measuring the signal.

[3] The accuracy of 500 W and 5 kW is specifi ed after NULL function, which is used to subtract the test lead resistance and the thermal effect.

[4] For the range of 50 M W and 500 MW, the R.H. is specifi ed for <60%.

[5] The accuracy is specifi ed 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 specifi ed 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: <+ 4.2V.

[2] AC mV/V and AC µA/mA/A specifi cations are true RMS AC coupled, valid from 5% to 100% of range. The crest factor may be up to 3 at full scale, up to 5 at half- scale, except for

1000 mV and 1000 V ranges, where the crest factor is 1.5 at full scale and 3 at half scale.

[3] For U1251A / U1252A / U1253A, the input signal is lower than 20,000,000 V-Hz (the product of voltage and frequency).

[4] Input current >35 µArms.

[5] Current can be measured from 2.5 A up to 10 A continuously. An additional 0.5% needs to be added to the specifi ed 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.

[6] Input current < 3 Arms.

[7] The additional error to be added as frequency >20 kHz and signal input <10% of range: 3 counts of LSD per kHz.


[9] Crest factor ≤ 3.0 at full scale, 5.0 at half scale except the 1000 mV and 1000 V ranges where it is 1.5 at full scale, 3.0 at half scale. For non-sinusoidal waveform, add 0.1% of reading

± 0.3% of range.

[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 k W 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 specifi cations defi ned.

[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.
