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

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.
