GDM-8352 Digital Multimeter

Goodwell introduces the new 5 1/2 Dual Display Digital Meter - GDM-8352, replacing the GDM-8251A and GDM-8351, which also utilizes a VFD dual display, a maximum display of 199999 digits, 0.02% DC voltage basic accuracy, and a USB / RS232C communication interface to provide users with accurate measurement functions, clear numerical observation, and the convenience of linking to a personal computer. interface, providing users with accurate measurement functions, clear numerical observation, and the convenience of easy linkage to a personal computer.

In addition to basic measurements such as AC/DC voltage, AC/DC current, 2-wire/4-wire resistance, temperature measurement, short-circuit beeping and diode test functions, the new meter is equipped with the ability to measure capacitance. A variety of auxiliary functions such as Max/Min, dB, dBm, Compare, Read Hold, Arithmetic (MX+B, 1/X, %), etc. are also provided to assist in meeting the needs of measurement applications such as in-process testing, teaching labs, and inspection situations.

In terms of external control, the pinout of the Digital I/O not only provides the signal outputs commonly used in the comparison function, but also allows users to define the signal outputs of each pin by themselves. In the customization mode, users can treat this I/O as a simple digital hardware and use the signals of each pin to achieve the external control needs, saving users the trouble of creating hardware circuits.

In terms of remote control and data acquisition, considering the user's habitability and the universality of the system interface, the meter provides standard RS-232C and USB interfaces, which can be used to write control programs and read the measurement results; especially on the USB interface, it also allows the user to choose whether the interface is in USBBCDC or USBTMC mode; when the USBTMC mode is selected, the user can control the USB interface instrument just like the GPIB interface instrument, without using the relatively expensive GPIB connection cable. When the USBTMC mode is selected, the user can control the USB interface in the same way as a GPIB interface instrument, without the need to use the relatively expensive GPIB connection cable.

Dual measurement/dual display
Like Goodwell's 6 1/2 and 5 1/2 digit meters, the GDM-8352 utilizes dual VFD displays to support combinations of measurement items, such as monitoring DC voltage and current presented by a component in a test line or measuring DC voltage with an AC component...etc. The results obtained from a single measurement can be presented separately and simultaneously on the individual displays. The results of a single measurement can be presented separately and simultaneously on individual displays. This not only saves the user's time in measurement, but also eliminates the need to switch displays in observation.

Selectable measuring speeds
The GDM-8352 also boasts one of the faster measurement speeds in its class and offers a choice of 3 file speeds - Slow/Medium/Fast; for example, in Fast mode, DC voltage measurements can reach up to 320 readings per second;
