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 .

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.

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.

Our thermal measurement function supports 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.

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!

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.

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.

The M3500A Series is equipped with a standard USB interface. This easy-to-use and hot plugin

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.

We provide MatLab® and LabView® applications that allows user to do a variety of tasks. Also

feature the PT-tool that can acquire date directly from the measurement into MS word® or

Excel®. Even without MS Word® or Excel®, user can choose our PT-Link which is a standalone

application.
