High Precision, Low Cost

The M3500A provides stability, accuracy, and speed at a very low cost. It has 0.0035% DC voltage accuracy on the 10V range and 0.01% resistance accuracy on the 10KΩ range. At 6.5 digits, the M3500A delivers 55 triggered readings/s via the USB remote interface but only when the PCL is at 60Hz. At the fast 4.5 digit setting, it reads over 2000 readings /s into its 2000 reading internal buffer.

The M3500A provides a wide number of measurement ranges and functions:

  1. DC voltage: 0.1V, 1V, 10V, 100V, and 1000V
  2. AC voltage: 0.1V, 1V, 10V, 100V, and 750V
  3. DC current: 10mA, 100mA, 1A, and 3A
  4. AC current: 1A and 3A
  5. Two- and four-wire resistance: 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ, and 100MΩ.
  6. Frequency: From 3Hz to 300 kHz
  7. Period measurement
  8. Diode measurement
  9. Programmable A-D converter and filter settings for signal to noise optimization

Additionally, eight mathematical operations can be performed on measurement readings: RATIO, %, Min/Max, NULL, Limits, mX+b, dB, and dBm testing. Microsoft® Office, Word, and Excel add-in tools allow remote storage and recall of the measured values from these applications. A graphing utility enables charting of measurements versus time for trending and noise observations.

TMC compliant USB remote interface enables control from a PC for consistent test/calibration procedure execution and easy re-use of existing SCPI programs, including Agilent Model 34401A command emulation.

Simple to Use

The M3500A can be setup quickly and is very easy to use. It has a high contrast front panel and keypad that are intuitive and user-friendly. An easy to read 5×7 dot matrix, vacuum fluorescent display (VFD) offers three-color enunciators so users can easily distinguish each function symbol by its color.

Strength and Versatility

With its rugged construction and rubber bumpers, the M3500A has the durability to withstand bench, portable, or stacking applications. A sturdy carrying handle facilitates transportability.

Applications

The M3500A USB Digital Multimeter is ideal for applications in electronic device, circuit, module, and product testing; low cost production testing of electrical and electronic components, sub-assemblies, and end products; and student lab assignments. Typical applications include:

  1. Test Engineers: Manual and semi-automatic electrical functional test
