Its exceptional features include 50,000 counts, VFD dual-display, 0.02% basic DC voltage accuracy and a USB protocol connector to provide users with measurement precision, lucid data observation, and the convenience to connect with the personal computer. The GDM-8300 Series not only supports the fundamental measurement items provided by general multimeters, but also equips with capacitance and temperature measurement functions. Furthermore, the GDM-8300 Series also provides many auxiliary functions to meet the measurement requirements for manufacturing process tests, educational experiments and testing facilities. With respect to storing and retrieving data, the GDM-8300 Series has two methods to offer: rst, the USB ash drive storage function--- operating alone without connecting with a computer second, USB interface (virtual COM port) and optional GPIB interface (must be installed in factory) for automatic measurement system users to conveniently save and retrieve data. The major distinction between GDM-8342 and products in the same category is that GDM-8342 provides USB ash drive storage function, P F A ,- which allows users to conveniently save data into a USB ash drive through a simple and proper setting. This unique function, different TT from other digital multimeters which must rst save data into its T ~~ it - : /l L k T HA is:-, 0 IT: l+ J *i-%. 0 own internal memory then transfer out the le, or connect multimeters with a computer to retrieve data, not only saves operational time but also cuts down the cost and time ofdeveloping programs. The USB ash drive storage function incorporates two modes -- basic and advanced, which can be selected from the front panel. X/hen the ---~ne.. , basic mode is on, data will be saved into an automatically established new folder (time of established le will be determined by system The USB storage function allows each ash drive to establish 100 default) and the starting time ofdata logging will use a xed time folders (GW000 ~ GW099). Each folder has a capacity of saving marker (00hr: 00min: 00sec). For advanced mode, users can designate 5,000,000 data les (which are divided into 100 suble names, a le path to save data or establish a new folder and the starting time therefore, each sub-le name can save 50,000 data les. Take folder ofdata logging is determined by users inputs (for instance: 23hr: G X/000 as an example, internal le names are C- X/00O 00 - 45min: 32sec). The number of data les can be saved in one second G X/00 99). The storage format is CSV, which can open les and is determined by the speed of selected function. conduct le analysis by existing tools.
