Product details

GW Instek GDM-8251A 5 ½ Digit Dual Display Digital Multimeter

• GDM-8251A : 5 ½ Digits(120,000 Counts Max.)
• VFD Two Colors Display
• 0.012% DCV Accuracy & True RMS (AC, AC+DC)
• 9 Major Measuring Functions and 10 & Advanced Measurement Functions
• 2W/4W Resistance Measurement
• High Voltage 1000V and 10A Current Range
• Standard Interface : RS-232C, USB Device, Digital I/O
• Free PC Software (DMM-VIEWER), & LabVIEW Driver

GDM-8255A/8251A portable precision multimeters feature 199,999/120,000 counts, a dual display,
a 0.012% DCV accuracy and 2w/4w measurement. The VFD display technology provides the excellent
observation of contrast and brightness.

GDM-8255A/8251A carry 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 remote control and data capturing for ATE

For convenient PC-based remote control and extensive data capture, GDM-8255A/8251A include
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. 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 effective upgrade path compared with purchasing dedicated instruments.(OPTIONAL FOR GDM-8255A ONLY)
