Dual Masurement/Dual Display
The GW Instek 5-1/2 Digit GDM-8351 Dual Measurement Multimeter features VFD dual-display, maximum 120,000 counts, 0.012% basic DC voltage accuracy and USB/RS-232C connectors to assure measurement precision, lucid data observation, and the convenient connection with the personal computer.
The VFD dual display supports the possible combinations of measurement items. For example, the DC voltage and current or DC voltage with AC element will appear when monitoring components of test wiring. The results of each measurement will simultaneously appear on different displays that saves time and the trouble of selecting displays while reading measurement results.
In addition to the fundamental measurement items such as AC/DC voltage, AC/DC current, AC+DC voltage/current, 2W/4W resistance, frequency, temperature measurement, continuity beeper and diode test, GDM-8351 also equips with the capacitance measurement function. Furthermore, the GDM-8351 also provides many auxiliary functions, including maximum/minimum values, dB, dBm, compare, reading hold, algorithms (MX+B, 1/X, %) etc. to meet the measurement requirements for manufacturing process tests, educational experiments and testing facilities.
The GDM-8351 has one of the fastest measurement speeds. Three selectable measurement speeds are available &Mdash; slow/medium/fast. For instance, the DC voltage measurement can reach 320 readings per second on the fast mode, which can maximize measurement effectiveness.
For the external control, the pin of digital I/O interface not only provides the signal output frequently used by the compare function, but also allows you to define signal output for each pin. Under the self-definition mode, you can apply the I/O as a simple digital hardware. The external control requirement can be achieved by signals from each pin so as to help users reduce trouble of making hardware.
The GDM-8351 provides standard RS-232C and USB (USB-CDC or USB-TMC) interfaces to edit control programs and read measurement results. While USB-TMC is selected, you can control the instrument with the USB interface exactly the same as controlling instrument with the GPIB interface; negating the need for the expensive GPIB interface and cable.
GDM-8351 provides free Excel add-ins that allow Microsoft Excel to establish a Marco to directly control the setting of GDM-8351 to record the measurement results. The recorded data will be synchronously transformed into graphic displays via Excel's drawing function.
Included with GDM-8351: Safety instruction sheet, Power cord, one (1) GTL-207 Test Lead and user's manual, driver and software on CD.
