Is the resolution of your current mulitmeter inadequate to read the smallest signal? Need an easy to use multimeter with data-logging? Take a look at the GoodWill GDM-825xA series 5 1/2 digit dual-display digital multimeter. It features a DC voltage accuracy of 0.012% with an industry-leading response time. With robust hardware and software the GDM-825xA series will save time on debugging and analysis whilst saving you money. 

 

The GDM-8255A/8251A carries an extensive list of standard measurement items with a dual-display allowing two measurement items to be displayed simultaneously. Advanced measurement functions, such as Max/Min, Hold, Relative value and Compare, are suitable for a multiplicity of applications such as production testing, research and field verification. The USB, RS-232C and 9-pin digital I/O interface are included as standard features for romte control and data capturing for ATE.

 

For convenient PC-based remote control and extensive data capture, the GDM-8255A/8251A includes DMM-Viewer software at no additional cost. DMM-Viewer mimics the operation of the multimeters on the PC, allowing you to quickly use the software with little effort.

 

The optional scanner card (GDM-SC1), creates a self-contained multipoint measurement solution with plug-in design. This approach eliminates the complexities of multipoint measurements and data processing. The scanner lets users effectively measure multiple channels connected to a single GDM-8255A.

Nine major measuring functions such as DCV/ACV, DCI/ACI, 2w/4w Resistance, Diode, Frequency, Continuity test and Temperature are provided on the GDM-8255A/8251A. The 0.012% DC voltage accuracy provides great precision for the DC voltage applications. In addition to the major measuring functions there are several advanced measuring functions such as Max, Min, dB, dBm, REL/REL#, Hold, Compare and Math functions ( MX+B, %, 1/X) to enhance the effectiveness of measuring results.

The GDM-8255A/8251A offer selectable measurement speed rates under different modes. The speed rates allow you to maximize measurement efficiency while maintaining sufficient accuracy. In fast mode, the instrument delivers 60 readings/sec (see table below), adequately meeting today's speed demands. The display can be turned off by pressing the OUTPUT ON/OFF button at anytime. When using remote control, the display can be turned off to increase the measurement speed by reducing the operating load.

 

 

Diverse Measuring Combinations with VFD Dual Color Display

 

Offering a variety of dual display combinations, the GDM-8255A/8251A allows a main measurement function and an auxiliary measurement function to be displayed at the same time. The dual measuring function will save measurement time when dealing with applications requiring multiple simultaneous parameters. The high quality dual color VFD (Vacuum Fluorescent Display) is strongly illuminated with a clear contrast for both red and green.

 

 

Multiple Standard Interfaces

 

The GDM-8255A/8251A provides multiple interfaces for PC connection as standard: RS232C and USB. With RS232 and USB as standard, remote control and data transfer is faster and smoother. Without the need for expensive propriety communication interfaces, costs are significantly reduced for PC control and monitoring. In addition, the digital I/O terminal outputs comparison measurement results to control external devices for ATE applications and the VCC output can be used as a power source for TTL or CMOS circuits.

 

 

Convenient PC Software

For convenient remote control and long data captures, the GDM-8255A/ 8251A is accompanied with free software, DMM-Viewer. This software allows users to remotely control the GDM-8255A/8251A without the need to issue commands or develop new program interfaces. DMM-Viewer's software interface resembles the GDM-8255A/8251A front panel, shortening training. For data capturing through a PC, the software allows you to observe measurement results before saving to a file for further study. Additionally saved files can be loaded and viewed as a graph. With DMM-Viewer, operating the GDM-8255A / 8251A multimeter can be much more effective.

 

 

Effective Multiple Measurement Scanner Card

 

 

Each scanner card has 16 general purpose channels and 2 extra channels for current (ACI, DCI) measurements. All channels are fully isolated (Hi and Lo). Up to two scanner cards can be inserted into each multimeter for a maximum of 36 channels. These optional modules not only provide customers with a complete hands-free multiple measurement solution, but also provide a cost effect upgrade path compared to purchasing dedicated instruments.
