Boost Your Measurement Speed & EfficiencyThe GDM-8261A is a high precision 6 V2 digit Digital Multimeter with dual measurement displays, ii measurement functions and i0 mathfunctions at high accuracy (35ppm DC voltage accuracy) to accommodate the most frequently performed parameter measurements invarious application fields today.The GDM-8261A adopts a scanner card, which carries 16 V-Channels and 2 I-Channels, to facilitate the measurements of multiple-testpoints on either a device or multiple devices all at a press ofa button. \X/ith this multi-point measurement capability, the GDM-8261A canbe used as a semi-auto ATE System to increase the throughput of manufacturing test or as a data logger to perform long term monitoringor characterization ofa DUT. A PC Software, DMM-Viewer, is available with GDM-8261A to support multi-channel panel setting and datalogging ofthe scanner card. Besides, a LabVlE\X/ driver is also supported to help user create his/her own virtual instrument on the PCscreen for easy programming. For ATE system measurements or remote control applications, both USB and RS-232C Interfaces areprovided as standard, and either GPIB or LAN can be selected as optional interface for the GDM-8261A.

The GDM-8261A offers two methods, both 2-wire and 4-wire, forresistance measurements. The 2-wire measurement is most commonlyused for resistance measurement in the range from 10052 to 10k§2.Whereas the 4-wire connection is normally applied for resistancemeasurement at a value lower than 100Q. When applied, 4-wiremeasurement automatically compensates the test lead resistance andconnector contact resistance to get an accurate measurement result.

The GDM-8261A is able to acquire and record 2 ~ 9999measurement readings for the “store” and “recall” functions.This allows an immediate observation ofthe maximum, minimum,average or standard deviation values of all the recorded datawhenever the data acquisition stops.

The “Math” function ofGDM-8261A includes four mathematicaloperations for measurements: MX+B, 1/X, Percentage and Stats.“MX+B" multiplies the measurement reading (X) by a factor (M) andadds/subtracts an offset value (B) to calculate linear offsets or scalesThe “1/X” function divides 1 by the measurement reading (X),calculating the inverse ofthe reading. The “Percentage” functioncalculates the ratio ofthe measured value to a target value using the

The GDM-8261A performs temperature measurement accommodating popular thermocouple types are supported for temperaturea wide range oftemperature sensors ofeither thermocouples or RTD measurement on the GDM-8261A. For RTD sensors, the GDM-8261A(Resistive Temperature Detectors). For thermocouples, the GDM-8261A calculates the voltage fluctuation arisen from the resistance variationuses voltage measurement terminals as the thermocouple input and due to temperature change. Either front panel terminals or scannercalculates the temperature from the voltage fluctuation. Most ofthe card terminals can be used as the input for temperature sensor.

For the convenience of remote control and long time data acquisition,

a free software, DMM-Viewer, is supported with the C-DM-8261A. Thissoftware allows user to remotely control the GDM-8261A without the

need to give commands or to develop programming software. DM M-

Viewer‘s human interface resembles the GDM-8261A front panel, whichsignificantly shortens the user’s learning time. For the data capturethrough a PC, the software allows user to continuously observe themeasurement results before saving them into a file. Further more,

the saved files can be loaded and viewed as a graph for data analysis.

When GDM-8261A works with scanner card for multi-pointmeasurements, the DM M-Viewer allows user to easily select the

measurement function and range for each channel and start

acquiring measurement data promptly. The GDM-8261A LabV|EW

driver is also available for free download. With this driver, the useris able to create a virtue instrument on the PC for the instrument

control. With DMM-Viewer & Lab\/IEW driver, the GDM-8261Abecomes a high value semi-auto ATE system without furthersoftware/hardware investments.
