Specification

The Array M3500A 6 1/ 2 digit multimeter is a versatile testing tool. In addition to the standard functions you' ve come to expect from a high quality digital multimeter, this unit also offers improved accuracy, expanded memory, new triggering capabilities, extraordinary sampling/ transferring speed and built-in USB and GPIB connectivity. The 6 1/ 2 digit M3500A DMM is designed with 7 1/ 2 digit techniques to provide user a stable, faster and accurate measurement. The M3500A is engineered with to reach high performance: Both of the sampling rate and the data transfer rate can achieve 2000 readings per second.

19 Full-Featured Functions
There are 11 measurements and 8 math functions: DCI, DCV, ACI, ACV, 2W© 4W© . Frequency, Period, Diode, Continuity, Temperature; Limits, Ratio, MX+ B, % , dBm, Db, Min/ Max, Null. In addition, Trigger and Memory functions are also involved. Our thermal measurement functions support two types of measurements: Thermocouples and RTDs. For thermocouples, it supports up to 7 types of sensors: E, J, K, N, R, S and T. The M3500A supports up to 10 channels ( 2-pole) multi-point scan. For using this option, the user needs to have an additional multi-point scanner card ( Model M3500-opt01) . The installation of the multi-point scanner card is very easy- just turn off the power and plug in the multi-point scanner card, and it is done!

Built-In USB Interface
The M3500A is equipped with a standard USB interface. This easy-to-use and hot plug-in USB interface has a high data-transfer rate over 2000 a truly high speed, both internal sampling rate and I/ O data rate, thus increase the measurement speed of your DMM. This model has an excellent performance on noise immunity. The core of this DMM is a powerful multi-slope analog to digital converter ( A/ D converter) helps the DMM to reach a high-speed sampling rate, filters out most noise, and still keeps a good measurement linearity. In addition, to reduce the environmental background noise, we have added four sets of earth ground on the meter' s front panel. And the copper conductors inside the meter also contribute to reducing thermal EMFs.
