M3500A

The M3500A trumps the 34401A in almost every regard. The M3500A is much more than a 6.5 digit DMM. Utilizing a 10 Channel or 20 Channel Scanner Card (optional) it is a data acquisition unit that provides the highest stability readings. Like all Picotest products, it’s backed by our 30 day refund policy.

What's included with all models
CD(User manual & software applications), power cord, test leads, and USB cable.
Three (3) Year Manufacturer's Warranty
To get the most that your new M3500A has to offer in data acquisition, add the removable 20 channel multi-point scanner card to your order.

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:

DC voltage: 0.1V, 1V, 10V, 100V, and 1000V
AC voltage: 0.1V, 1V, 10V, 100V, and 750V
DC current: 10mA, 100mA, 1A, and 3A
AC current: 1A and 3A
Two- and four-wire resistance: 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ, and 100MΩ.
Frequency: From 3Hz to 300 kHz
Period measurement
Diode measurement
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:

Test Engineers: Manual and semi-automatic electrical functional test
Development Engineers: Electrical/electronic circuit and product validation
Service/Calibration Technicians: Electronic product repair and calibration
Research Scientists: Electrical and physics experiments testing
Engineering Students: Electronic device and circuits experiment testing

Accessories
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:

Startup Software, PC utilities Included
PT-Tool application provides charting and graphing capabilities without programming to simplify setup, checkout, and basic measurement applications requiring graphical data representation. Scale, offset, and level can be adjusted to fine tune images for visual evaluation of signal and noise elements over time. Also includes tabular data and SCPI command prompt windows for maximum flexibility. Data sets can also be saved to disk files.
Microsoft Excel Add-In utility is also included and provides quick data import into standard Microsoft Excel spreadsheet, including selectable graphing, instrument settings, and number of data points collected. Data can then be analyzed through standard or options Microsoft Excel functions, including graphical, statistical, and trend charting. A version supporting Microsoft Word is also included for direct data import into reports.
