M3500A - 6.5 Digital multimeter


M3500A - 6.5 Digital Multimeter PICOTEST

Stability, Speed and Accuracy

The 6 1/2 digit M3500A DMM is designed with 71/2 digit techniques to provide user a stable, faster and accurate measurement. The following figure is the stability performance comparison between the typical 61/2 digit DMM and the M3500A
High Speed:2000 Readings / Sec 

The M3500A is engineered with expertise to reach such a 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, 2WΩ, 4WΩ, Frequency, Period, Diode Test, Continuity, Temperature, Limits, Ratio, MX+B, %, dB, dBm, Min/Max, and Null. In addition, Trigger and Memory functions are also involved. All functions above facilitate your measurement applications better. 

Temperature Measurements

Our thermal measurement functions support two types of measurements: Thermocouples and RTDs. For thermocouples, we support up to seven types of sensors: J, K, T, E, N, S and R, using a NIST Monograph 175 reference table. Moreover, for the RTDs temperature conversions, we adopt three types of standard: ITS-90, IEC751 and Callendar-Van Dusen standard in our thermal measurement functions. All these are made for user's convenience 

Multi-Point Scan


The M3500A supports up to 10 channels (2-pole) multi-point scan. For using this option, 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 the power off and plug in the multi-point scanner card, and it is done.


Dual Displays with 3-Color Annunciators

This model comes with a unique 5x7 dot matrix, VFD dual displays with three-color annunciators. User can easily distinguish each symbols by their colors.

Noise Immunity

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) This special A/D converter (p.s. patent is pending) helps the DMM to reach 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.

Built-in USB Interface

The M3500A Series 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 readings per second. It allows your DMM to reach a truly high speed, both internal sampling rate and I/O data rate, thus increase the measurement speed of your DMM.

Free Remote-Control Software

The Remote-Control Software, PT-TOOL & PT-LINK, is free and easy for user’s application. PT-TOOL is a stand-alone software which can imitate virtual M3500A operations on the PC, and allow users to transmit data in Excel format. In addition, PT-LINK under the Microsoft Word & Excel application provides users a simple function of getting values and diagrams.
