Keysight 34470A Digital Multimeter with 7.5 Digit Resolution 50,000 readings/s and Auto Calibration Truevolt DMM

Keysight Agilent 34470A Digital Multimeter 7½ Digit Basic Truevolt

The Keysight 34470A 7½ digit, Performance Truevolt Digital Multimeters offer higher levels of accuracy, speed and resolution.

1. Specifications are for 90-minute warm-up, integration setting of 10 or 100 NPLC, auto-zero on, AC slow filter. ACAL run within the last 2 days.

2. 20% over range on all ranges, except 1000 DCV, 750 ACV, 10 DCA, 3 DCA, 10 ACA, 3 ACA, and diode test have 0%.

3. Relative to calibration standards.

4. The 10 A range is only available on a separate front panel connector. Add 2 mA base per amp for inputs greater than 5 Arms.

5. Add this for each °C outside TCAL ±5°C.

6. Add this for each °C outside the last TACAL ±2°C.

7. Add this for each °C outside TACAL ±2°C.

8. Specifications are for 4-wire ohms function or 2-wire ohms function using math null for offset. Without math null, add 0.2 Ω additional error in 2-wire ohms function. The 100 MΩ and 1 GΩ ranges are 2-wire only. See the manual for low power ohms specification and measurement currents.

9. For each additional volt over ±500 V add 0.02 mV of error.

10. Specifications are for the voltage measured at the input terminals. The 1 mA test current is typical. Variation in the current source will create some variation in the voltage drop across a diode junction.

11. See user manual for details.

12. Actual measurement range and probe errors will be limited by the selected probe. Probe accuracy adder includes all measurement and ITS-90 temperature conversion errors. PT100 Ro settable to 100Ω ± 5Ω to remove the initial probe error.

13. The internal reference junction uses the U1180A or equivalent adapter. This has a typical performance of ±1.0°C. This internal reference junction can be adjusted for better accuracy. An external reference junction can also be used.

14. Specifications are for sine wave input > 0.3% of range and > 1 mVrms. 750 ACV range limited to 8 x 107 V.Hz. For each additional volt over 300 Vrms add 1 mVrms of error.

15. Low-frequency performance: three filter settings are available: 3 Hz, 20 Hz, 200 Hz. Frequencies greater than these filter settings are specified with no additional errors.

16. Specifications are for sine wave input > 1% of range and > 10 µArms.

17. Specifications are for sine wave input unless stated otherwise.

18. Square wave input specified for 10 Hz to 300 kHz for 1 second aperture. For shorter apertures, the minimum frequency requires > 2 cycles.

19. Input > 100 mV. For 10 mV to 100 mV inputs, multiply % of reading error x10. Amplitude 10% to 120% of range except 14% to 100% for the 750 ACV range. Specifications are for 1-second gate time (7 digits).

20. Specifications are for using Math Null zeroing. High dissipation factor capacitors may show different results than a single frequency measurement. Film capacitors usually have lower dissipation factors than other dielectrics.

21. The second burden voltage can be obtained by using the 10 A input range.

22. Sample rate (actual): 50.118 kHz (Aperture = 19.953 µs).

23. Thermistor type: 2.2 kΩ (model number 44004), 5 kΩ (model number 44007) and 10 kΩ (model number 44006)

Get more insight quickly: Truevolt DMM's graphical capabilities such as trend and histogram charts offer more insights quickly. Both models also provide a data logging mode for easier trend analysis and a digitizing mode for capturing transients.

Measure low-power devices: The ability to measure very low current, 1 µA range with pA resolution, allows you to make measurements on very low power devices.

Maintain calibrated measurements: Auto calibration allows you to compensate for temperature drift so you can maintain measurement accuracy throughout your workday.
